Hereditary deficiency of plasma prekallikrein (PPK) is a rare autosomal recessive disease. The affected patients are often asymptomatic and diagnosed incidentally during preoperative investigations or during hospitalization by isolated prolongation of activated partial thromboplastin time (aPTT). In this article, we report, a 46-year-old woman who was candidate for two invasive procedures (thyroid FNA and hysterectomy) and underwent preoperative evaluation. Due to prolonged aPTT with normal PT she was referred to the IBTO reference coagulation laboratory for specific coagulation assays. Ultimately, the examinations revealed severe PPK deficiency (<1%) with partial deficiency of factor XII level (25%).

Background: This study was conducted to evaluate the frequency of JAK2, CALR and MPL mutations in with BCR-ABL myeloproliferative neoplasms and their association with demographic data and hematologic parameters in a referral center, in the Middle East. Methods: Seventy-one patients with BCR-ABL negative myeloproliferative neoplasms were evaluated for JAK2 V617F, CALR type 1, type 2, and MPL by allele-specific PCR and conventional PCR from 2018 to 2019. Results: Twenty three patients were categorized as polycythemia vera and demonstrated JAK2 V617F in 91.3 % of these cases. Thirty-eight patients were classified as essential thrombocythemia and showed JAK2 V617F in 52.6%, CALR type 1 in 18.4%, CALR type 2 in 7.9% and no mutation in 21.1%. Seven patients were recognized as primary myelofibrosis and exhibited JAK2 V617F mutation in 57.1%, CALR type 1 in 14.3 %, CALR type 2 in 14.3% and no mutation in 14.3%. Three patients were diagnosed as MPN, unclassifiable and revealed JAK2 V617F mutation in 33.3% and no mutation in 66.6%.The age (59.15±13.10) and neutrophil percent (70.78±10.14) were higher in patients with JAK2 mutation compared to other mutations (p=0.000, and p=0.03). Platelet count was significantly higher in patients with CALR type 1 mutation (1240400± 402053) (p=0.000). Conclusion: JAK2 V617F was was associated with patients’ higher age and higher neutrophil count in CBC. CALR mutation had an association with higher platelet count. No MPL mutation was found in this study and it seems that its frequency is lower than what is expected in this region.

Dendritic cells (DCs) are key arms of immune system, which act in antigen presenting processes, and are considered as a bridge between innate and adaptive immune responses. DCs are found in both lymphoid and non-lymphoid organs. They are called interdigitating dendritic cells (IDCs) in secondary lymphoid organs. IDCs lack lineage surface markers and are positive for S-100 and vimentin. IDC sarcoma (IDCS) is a very rare neoplasm, which mainly affects lymph nodes, though there are reports of extra-nodal involvement. IDCS is thought to have poor prognosis. Although there is no consensus on the treatment modalities, such options as radicalsurgery, chemotherapy, and radiotherapy are performed depending on severity and site of the lesion. In this study, we present a case of IDCS in a 53-year-old male with a history of several skin lesions and prior diagnoses of basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and metatypical carcinoma (MTC).

Coronaviruses are considered to be one of the most significant human and animal pathogens. In late 2019, a new species of coronavirus was recognized as the cause of some pneumonia cases in Wuhan, China. The disease spread rapidly and made an epidemic in China and subsequently in almost all countries in the world. In February 2020, the World Health Organization (WHO) named it as COVID-19 standing for Coronavirus 2019 (1). Due to being a pandemic issue, it is needed to discuss various aspects of this viral disease. Recently, Yan Zhang et al. reported a case of coagulopathy and antiphospholipid antibodies in the patient with severe COVID-19 infection (2). Thus, one of the serious complications of COVID-19 that should be taken into consideration is coagulopathy with possible anti-phospholipid antibodies syndrome in these patients. In this regard, some studies also claimed that COVID-19 could cause venous and arterial thromboembolism because of excessive inflammation, hypoxia, immobility, and diffuse intravascular coagulation (3). Antiphospholipid syndrome is a systemic autoimmune disease with vascular and hematologic complications as venous and arterial thrombosis or pregnancy morbidity (4). It is well known that infectious agents are one of the major stimulators of the antiphospholipid antibodies in vivo (5), thus, COVID-19 can be a possible cause of this phenomenon within its infection period and consequently, positive results of antiphospholipid antibodies detection are not unexpected.

Background & Objective: Acute lymphoblastic leukemia (ALL) is a malignant disease that arises from various mutations in B or T-lymphoid progenitors. MicroRNAs (miRNAs) regulate gene expression by binding to the 3' untranslated region of protein-coding genes. Dysregulation of miRNA expression may result in the development of cancerous phenotypes. Therefore, for the first time in this field, the present study aims to investigate the effect of overexpression of miR-506 in Jurkat (acute T cell leukemia) cell line. Methods: In this study, Jurkat cell lines were cultured in RPMI-1640 medium. Next, miR-506 was transfected with concentrations of 50 and 100 nM with Lipofectamine 2000. The accuracy of the transfection was confirmed by the transfection of siRNA conjugated with FITC. 48 h after transfection, the cells were prepared for other tests (flow cytometry, MTT assay, and RNA extraction). The expression level of miR-506 in the cells was analyzed using the quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). Finally, SPSS 21 software was used for the data analysis. Results: According to our results, the viability of cells in concentrations of 50 and 100 nM was significantly higher than the control group. By overexpression of miR-506, the expressions of pro-apoptotic genes (p53, p21) and anti-apoptotic gene B-cell lymphoma-2 (BCL-2) are decreased and increased, respectively. Conclusion: This study showed that miR-506 may function as an oncogenic miRNA in the T- ALL cell line. In conclusion, overexpression of miR-506 leads to an increase in viable cancer cells.

Background & Objective: FLT3-ITD has been recently used as a molecular prognostic marker for risk classification in acute myeloid leukemia (AML) therapy. In this study we aimed to investigate the association of FLT3-ITD gene mutation with bone marrow blast cell count, CD34 expression as malignant cell burden, cyclin D1 and Bcl-xL expressions as indexes of cell proliferation and anti-apoptosis and human equilibrative nucleoside transporter 1 (hENT1) expression as cytarabine transporter during AML treatment. Methods: We investigated FLT3-ITD mutations, bone marrow blast cell count, CD34, cyclin D1, Bcl-xL and hENT1 expression in bone marrow aspirates from 22 de novo AML patients in a cross sectional study. Results: FLT3-ITD mutations were observed in 5 out of 22 de novo AML patients (22.7%). Patient with FLT3-ITD mutations had higher blast cell counts (79.5% vs 56.1%, p =0.004). In patients with FLT3-ITD mutations, CD34 and cyclin D1 expressions were higher (MFI 328.80 vs 25.78, p =0.003 and MFI 74.51 vs 57.15 p =0.005) than the patients without mutations. hENT1 expression in AML with FLT3-ITD mutation was lower (MFI 29.64 versus 56.32, p =0.0000) than in mutation-free AML. There was no significant difference in Bcl-xL expression between patients with and without mutations (p =0.61). Conclusion: A significant association was found between FLT3-ITD gene mutations in AML patients with bone marrow blast cell count, CD34, cyclin D1 and hENT1 expressions, however no association was obtained with Bcl-xL expression. These findings support the role of such mutation in pathogenesis of AMLand its contribution in rearrangement of standard therapy with cytarabine in management of AML.

Background & Objective: Matrix metalloproteinases-9 (MMP-9) is one of the most important enzymes to breakdown extracellular matrix which plays a major role in tumor invasion and metastasis. This study aimed to determine tumor MMP-9 expression in non-small-cell lung carcinoma (NSCLC) and whether it is associated with histopathologic factors and has prognostic value to affect overall survival (OS). Methods: The specimens of 92 patients with NSCLC diagnosis were included. Tumor sections were stained by immunohistochemistry method. Using scores for the percentage of cells positively stained and the intensity of staining, MMP-9 expression total score was classified as low-score (scores of 0 to 2), moderate-score (scores of 3 to 5), or high-score (scores of 6 or 7). OS was defined as the time interval since the diagnosis of NSCLC to the status at the last follow-up (dead or alive). The follow up period was up to 70 months. Results: About 74% of undifferentiated specimens (grade III tumors) showed high scores for MMP-9 expression which was significantly higher than moderately differentiated tumors (25% had high scores for MMP-9 expression) and well differentiated ones which did not have high scores (p <0.001). A total of 74 patients (80.4%) died during the follow-up period. Of this, 36% had high scores for MMP-9 expression. In contrast, none of the patients who were alive at the last follow-up had high scores for MMP-9 expression (p <0.001). Median OS was significantly lower in high score group (6 months) compared to moderate score (9 months) and high score group (15 months) (p <0.001). Conclusion: MMP-9 expression may serve as a significant prognostic factor for mortality and overall survival in NSCLC. Undifferentiated tumors significantly express higher MMP-9 immunohistochemically.

Background & Objective: Acute promyelocytic leukemia (APL) with t(15;17)(q22;q12) is a relatively common subtype of acute myeloid leukemia (AML). Here, our objective was to ascertain the survival of patients with this leukemia in north-east of Iran. Methods: Survival rates of 42 APL patients with t(15;17)(q22;q12) were assessed. Clinical information was obtained from archived medical records. Statistical analysis was performed by SPSS 18 software using log-ranked test and Kaplan Maier survival analysis. Results: Females and males comprised 49% and 51%, respectively. The mean age at diagnosis was 34.3 ± 14.1 years old. During the study period, 17 demises occurred in males, while this number was 7 in females. The mean survival of patients (month) was 23.22 ± 3.57 (95% CI: 16.21 ± 30.2). The five-year survival rate obtained 30%. Regarding demographic and clinical features, the highest rates of 5-year survival were recorded in patients with 20-35 years old (47.6%), males (51%), white blood cell count <10±/l (48%), and platelet count >140 ± /l (100%). Conclusion: Younger age, lower WBC count and higher platelet count were significantly associated with longer survival in AML patients with t(15;17)(q22; q12).

Background & Objective: Cytogenetic abnormalities in Multiple myeloma (MM) has emerged as the most important factor that determine the prognosis and survival. Fluorescence in situ hybridization (FISH) can detect a greater number of cytogenetic abnormalities as compared to conventional karyotyping and hence has become the standard test in determining genetic abnormalities in MM. The present study was planned as there is an unmet need to find out various cytogenetic abnormalities and to implement them in prognostic stratification by Revised International Staging System (R-ISS) among Indian population. Methods: A single institution retrospective study was conducted among a total of 117 patients newly diagnosed as Multiple Myeloma. They were analyzed for various cytogenetic abnormalities by using interphase FISH (iFISH) and were staged according to Revised International Staging System (R- ISS). Results: Out of the 117 patients studied, deletion 17p13 (p53) was present in 16 patients (13.67%). Thirty patients (25.64%) showed deletion 13q14.3. Three patients (2.56%) were detected to have t(4:14).Two patients (1.7%) had t(11:14) and t(14:16), respectively. Total of 19 patients (16.23%) in our study exhibited high risk cytogenetics and two among them had more than one high risk cytogenetic abnormalities. There was a 66.4% moderate correlation between ISS-III and high-risk cytogenetics which was statistically insignificant. Of the total 117 patients, 37 (31.62%) were staged R-ISS III. Conclusion: High risk cytogenetics was found in 16.23 % of our study population and del 17p13 was the most common high-risk cytogenetic abnormality. Of the studied subjects, 31.62% had R-ISS III, which is significantly higher compared to western population.

Background & Objective:Although the antigen expression patterns of acute lymphoblastic leukemia (ALL) are well known, this study attempted to evaluate commonly used immune markers for immunophenotyping of acute leukemia to set the minimum of necessary diagnostic panels by flow cytometry.Methods:This study evaluated 89 patients referred from all over the country to the Iranian Blood Transfusion Organization (IBTO) in Tehran from 2013 to 2015. We compared the immunophenotype patterns of childhood and adult ALLs including 69(77.5%) B-cell lymphoblastic lymphoma (B-LBL), 2(2.2%) Burkitt’s lymphoma (BL), and 18(20.2%) T-cell lymphoblastic lymphoma (T-LBL) cases using flowcytometry with broad antibody panel.Results:CD19 and CD79a were the most frequent markers for B-LBL while CD7 was the most sensitive marker in T-LBL; the frequency of CD7, CD3, and CD5 antigens were 100%, 38.9%, and 88.9%, respectively. TdT+/CD34+ was significantly higher in adult B-LBLs than children, which indicates blast cells are more immature in adults. In addition, CD10 and cCD79a were significantly higher in children with B-LBL like as CD5 and CD8 in children with T-LBL. Aberrant phenotypes including CD13, CD33, CD7, and CD117 were found in 7(10.1%) cases of B-LBL. These phenotypes were CD117, HLA-DR, and CD33 in 7(38/9%) cases of T-LBL. Expression of CD117 aberrant myeloid antigen was significantly more associated with T-LBL than with B-lineage ALL.Conclusion:Significant differences were observed in antigen-expression patterns between adult and childhood ALLs. Further studies are needed to correlate specific markers with recurrent cytogenetic abnormalities and prognosis with therapeutic response.

Mast Cell Leukemia (MCL), a rare subtype of systemic mastocytosis is defined by bone marrow involvement as atypical and aleukemic mast cells, if more than 20% and less than 10% of peripheral WBCs are mast cells, respectively. We met a case of aleukemic MCL presenting with anemia and ascites for 2 years, referred for BM evaluation, suspicious of leukemia. Our findings included BM involvement by diffused aggregates of oval- and spindle-shaped atypical mast cells, lacking mature mast cells and other hematopoietic cells. The mast cells were absent in peripheral blood smear. Further assessments showed positive reaction of mast cells metachromatic granules with Tryptase, Giemsa and Toluidine blue stains, the expression of CD117/KIT and CD45 by immunohistochemistery, and elevated level of serum Tryptase. Radiologic investigations revealed generalized lymphadenopathy, and massive hepatosplenomegaly, followed by the cervical lymphadenectomy, and liver wedge biopsy. Suspicious peritoneal lesions were identified and underwent excisional biopsy. Microscopic evaluations showed lymph nodes and liver involvement by cancer cells and the same features in peritoneal seeding. Multiple organs damage progressed in few months and the patient died despite surgery and chemotherapy. In conclusion, we report an extremely rarecase of aleukemic MCL with multiple organs damage such as liver, peritoneum, spleen, gastrointestinal tract and BM, presenting by ascites. According to this case and previous parallel studies, we suggest some clinicopathologic features in favor of poor prognosis, including the presence of multiple organs damage, hepatomegaly, ascites, peritoneal seeding, the absence of mature mast cells and other hematopoietic cells in the BM, and elevated serum Tryptase level.

Dear Editor, Dengue is an important arbovirus infection. This infection can result in an acute febrile illness. The important hematological abnormalities included hemoconcentration and thrombocytopenia (1). Due to the decreased platelet count, the patient might develop petechiae and hemorrhagic complication. In endemic area, the presumptive diagnosis of dengue is usually derived by the clinical findings (1). Sometimes, the atypical clinical presentation of dengue can be seen. The dengue without thrombocytopenia is possible and might be difficult for diagnosis (2). Here, the authors present an interesting case of dengue with platelet count and no hemocon-centration. The automated hematogram can help explain the aberrant complete blood count finding. The patient was a 13 years old female patient. The chief complaint was high fever for 4 days and petechiae for 1 day. The tourniquet test was positive. The complete blood count was done and the hemoglobin level was 12.4 g/dL and platelet count was 276,000/mm3. In the present case, there was no thrombocytopenia and no hemo-concentration. However, the autoamted hematogram (Figure 1) showed flag that platelet interpretation was possible. From history taking, the patient was a known case of beta-thalassemia/hemoglobin E disorder. The additional dengue NS1 Ag test was positive. The patient was diagnosed to have dengue and received the standard fluid replacement therapy. She got full recovery within 1 week. In the present case, the unexpected normal platelet count despite overt petechiae might be explainable by the automated hematogram. The patient had the underlying hemoglobin disorder problem that results in anisopoikilocytosis and microcytic anemia. With the underlying abnormal hematological parameter, anemia, no hemoconcentration can be explained. Regarding the platelet count, the microcytosis, anisocytosis and poikilocytosis can interfere with the platelet count in autoamted hematology analytical process. Nevertheless, the automated hematogram and flag can help explain and assist the physician in charge for further use of definitive diagnosis test for dengue.

Background and Objective: Janus kinase 2 (JAK2) and Myeloproliferative Leukemia (MPL) mutations are confirmatory indicators for Myeloproliferative Neoplasm (MPN). The current study was performed to determine the frequency of MPL mutation in MPN patients without JAK2 mutation, in order to assign MPL mutation frequency in North-East of Iran.Methods: Total of 105 negative JAK2 cases including 5 Myeloproliferative Disorders (MPD), 15 Polycytemia Vera (PV) and 15 Essential Thrombocytosis (ET) who referred to Qaem Medical Center were assigned to this study. ARMS-PCR was carried out for measuring MPL mutations. Results: A significant difference was observed between MPL mutant and non-mutant groups from overview of MPL mutation (P=0.00001). From the total studied population, 14.28% were ET cases and 4.71% of them had splenomegaly. About 66.66% had thrombocytosis and 33.33% of all the individuals had leukocytosis according to WHO criteria, and 4.76% of non-MPL mutant individuals had splenomegaly (P=1). This mutation was reported in 4-6% of ET and PMF individuals. In this research, 4.76 % of studied individuals had MPL (W515L/K) mutation, which were diagnosed with ET.Conclusion: Generally, the presence of JAK2 and MPL mutations are the most important criteria for MPN diagnosis. The obtained frequency of MPL mutation was similar to previous studies. Despite the high frequency of JAK2 and Philadelphia abnormality, MPL mutation was rare in myeloprolifrative disorders. Further studies are suggested to investigate its prognostic effects for these diseases.

Background and Objectives: The mesenchymal stem cells derived from peripheral blood (PB) have been recognized as a promising source for allogeneic cell therapy. The aim of this study was to investigate the isolation, growth and differentiation ability of peripheral blood-isolated mesenchymal stem cells. Methods: The mononuclear cells were purified from fresh peripheral blood using density gradient centrifugation then cultured in a suitable medium, expanded and characterized. In the following, these cells were cultured in specific adipogenic and osteogenic differentiation media.Results and Conclusion: In spite of the absence of any stimulating factor, the cells adhered to the flasks and developed a rather homogeneous, spindle-shaped morphology after consecutive passages. The cells were confirmed to have mesenchymal phenotype by expression of specific markers (CD90, CD105, and CD73) and absence of CD45 marker, which is specific for hematopoietic stem cells. They could differentiate into lineage-specific committed cells (osteoblasts and adipocytes). According to the findings, the conventional, labour-intensive and time-consuming approaches are not necessary to obtain an optimal number of cells from peripheral blood. This relatively accessible and minimally invasive source of stem cells may open a new era for practical exploitation in regenerative medicine.

Acute myeloid leukemia (AML) as a distortion of blood cells involves the differentiation of hematopoietic stem cells. Several studies established the irregular overexpression of specific genes is a common finding in patients with AML. The ectopic viral integration site-1 (EVI1) gene is a proto-oncogene subject to alternative splicing, and encodes a zinc-finger protein that acts as a transcriptional regulator in early development. Forced overexpression of EVI1 in hematopoietic progenitors later induced a myeloid differentiation block. The current review aimed at determining the prognostic value of EVI1 expression in patients with AML in the age range of one month to fifteen years. The scientific databases including PubMed, Google Scholar, EMBASE, Scopus, and ISI published up to January 2016 were searched using the conformity keywords and a total of four articles were studied. Three articles declared higher overexpression of EVI1 in patients with mixed-lineage leukemia (MLL) rearrangements. The percentage of overall survival (OS), reported in two articles, decreased in AML patients with high EVI1 expression. A study reported that the relationship between EVI1 expression and OS was negligible in cases with and without EVI1 expression. Another study showed significant differences in event free survival (EFS) and OS in the group of patients with positive MLL-AF9 between EVI1+ and EVI1- patients. The current study revealed that high EVI1 expression was not a poor prognostic factor in pediatric patients with AML. And this gene expression was mainly prognostic concomitantly by other factors such as MLL rearrangement, MEL1 expression, and white blood cell (WBC) count.

Multiple Myeloma is a neoplasm of B cell lineage characterized by excessive proliferation of abnormal plasma cells. It is characterized by a clinical pentad of 1) anemia, 2) a monoclonal protein in the serum or the urine or both, 3) bone leisons and or bone pain, 4) hypercalcemia >11.5g/dl and 5) renal insufficiency. Non secretory multiple myeloma is a rare variant of the classic form of multiple myeloma and accounts for 1% to 5 % of all cases of multiple myeloma. The clinical presentation and radiographic findings of non-secretory multiple myeloma and multiple myeloma are the same. The diagnosis of multiple myeloma requires the demonstration of monoclonal gammopathy in the serum or urine. In non-secretory multiple myeloma, however no such gammopathy can be demonstrated, making the diagnosis more difficult. We describe a 60 year old woman who initially presented with back pain which when further investigated by complete blood count revealed hemoglobin of 13g/dl, Total Leukocyte Count of 10,890 and platelet count of 1.5 lac/cmm. Viral markers revealed HCV positive. Hypercalcemia with a serum calcium level of 12.5g/dl was also demonstrated. MRI revealed multiple lytic bony lesions. No monoclonal gammopathy was found in the serum or urine and bone marrow biopsy showed marked plasmacytosis of > 45%. We present a case of Non Secretory multiple myeloma because of its illusive nature and rare entity.

Verrucous carcinoma (VC) is a rare variant of well differentiated squamous cell carcinoma (SCC) which is usually found in oral cavity mucosa. Cutaneous verrucous carcinoma is a rare entity and in this paper we report a 43 years old man with VC superimposed on chronically inflamed skin of ileostomy site. Previously, he was operated to treat rectal adenocarcinoma and has had ileostomy for six months. The skin lesion was resected totally during surgical operation for ileostomy closure. Histopathologic examination confirmed the diagnosis of cutaneous verrucous carcinoma. Post-operative follow up shows no evidence of recurrence after six months. We suggest patient’s training for follow up visits in order to early detection of osteomy site complications including neoplastic changes.

Background and objective:Breast cancer is the most common malignancy among women. The Neoadjuvant chemotherapy is the treatment of choice for non-operable tumors. The Ki67 is a proliferation marker that can be used to predict the therapeutic response to chemotherapy and the patients' prognosis. Methods: This retrospective study was carried out on 55 consecutive patients with breast cancer referred to a Training Tertiary Healthcare Center in Kerman, Iran since 2009 to 2014. After diagnostic approval, the tissue samples of patients were examined for estrogen and progesterone receptors, ki67 and HER2-neu markers by using immunohistochemical staining. Then the patients were treated with 6 cycles of Neoadjuvant chemotherapy regimens by Doxorubicin and Taxans or 4 chemotherapy cycles, containing Anthracycline and Cyclophosphamide and 4 cycles of Paclitaxel. After mastectomy, their samples were reexamined for ki67 again and classified into three groups (low: ki67<15%), medium (Ki67 = 16-30%) and high (Ki67> 30%). Results: Before chemotherapy, 54.5% of the patients had high expression of Ki67. But after chemotherapy, 52.7 of the patients had complete therapeutic response showing that the Ki67 level was reduced significantly (P=0.003). Conclusion: Before and after Neoadjuvant chemotherapy, Ki67 measurements may be used as a predictive marker of therapeutic response.

Background & objective: Introduction: First detection of any solid tumour as metastatic deposits in bone marrow directs clinicians to start searching for the primary tumour. Detection of bone marrow metastasis determines the stage of the malignancy, prognosis, mode of treatment, chemotherapeutic response and follow-up in case of relapse. The aim of the current study was to analyse the clinico-haematological presentation and morphological pattern of infiltration of solid tumours detected first as metastatic deposits on bone marrow examination. Methods:Three-year retrospective analysis of MGG-stained bone marrow aspiration smears and touch imprints of the bone marrow biopsy and Hematoxylin and Eosin (H&E) stained histopathological sections of biopsies was performed at the Department of Pathology at a tertiary care institute (January 2014 to December 2016). The morphological pattern of metastatic deposits and haematological profiles of the patients were analysed. Exclusion criterion was the presence of hematolymphoid malignancies. Results: In 22 cases, bone marrow was the first site of detection of metastasis. The age of the patients ranged from 3 years and 10 months to 82 years, with equal gender predilection. Overall, 16 cases had cytopenias, 9 cases each had leucocytosis and leukoerythroblastic presentation. The metastasis was from Ewing’s sarcoma, prostate carcinoma, gastric adenocarcinoma invasive duct carcinoma breast, gallbladder carcinoma, lacrimal duct carcinoma and invasive papillary urothelial carcinoma. Conclusions: Bone marrow examination is a cheap and reliable investigation to detect metastasis in an unsuspecting case. Bilateral trephine biopsies are recommended to increase the efficacy of detecting bone marrow metastasis.

Background and objective: Langerhans cell histiocytosis (LCH) is a rare histiocytic proliferative disorder of unknown etiology and mainly affects young children. The histological feature is granuloma-like proliferation of langerhans-type dendritic cells. Although the possible role of viruses such as Epstein-Barr virus (EBV, Human Herpes virus -4), Human Herpes virus-6 (HHV-6), Herpes Simplex virus (HSV) types 1 and 2 and Cytomegalovirus (CMV, Human Herpes virus-5) is suggested in the pathogenesis of LCH by some investigators, its exact pathophysiology has not been cleared yet. In this study, we investigated the presence of HSV types 1 and 2 in Iranian children with LCH Methods: In this retrospective study, we investigated the prevalence of presence of HSV types 1 and 2 (in 30 patients with LCH), using paraffin-embedded tissue samples and 30 age and tissue-matched controls (operated for reasons other than infectious diseases) from the Department of Pediatric Pathology, Tehran, Iran, by nested Polymerase Chain reaction method. No ethical issues arose in the study, because only the pathology reports were reviewed and patients were anonymous. Results: We failed to find HSV types 1 and 2 DNA in any of the 30 patients with LCH or the control group. Conclusion: According to our findings, HSV types 1 and 2 do not appear to have any etiologic role in the pathogenesis of LCH in Iranian children. These results are in accordance with previous investigations with negative findings.

Background & objective: Pancytopenia is the reduction in the number of all 3 major cellular elements of blood and leads to anemia, leukopenia, and thrombocytopenia. A wide variety of etiologies result in pancytopenia including leukemia, aplastic anemia, and megaloblastic anemia. The current study identified the different etiologies of pancytopenia based on bone marrow examination in Iranian patients with pancytopenia. Methods: A total of 683 cases of pancytopenia with various etiologies were selected for this retrospective study. Bone marrow biopsy was performed with the standard technique using Jamshidi needle. The inclusion criteria for patients with pancytopenia were hemoglobin (Hb) 9/L, and platelet count 9/L. Results: In the present study acute leukemia was the first most common etiology detected in 235 (35.4%) patients in which acute myeloid leukemia (AML) comprised the majority of cases 142 (21.4%), followed by myelodysplastic syndrome (MDS) 100 (15%). In patients less than 20 years old, acute leukemia was also the commonest cause identified in 56 (57.7%) cases in which acute lymphoblastic leukemia (ALL) with 38.7% was the most common etiology; however in adults (>45 year old), AML accounted for the majority of cases 76 (53.5%). Conclusion: Since acute leukemia was the commonest etiology in both young and adults in which AML accounted for the majority of cases with pancytopenia in Iranian population, there was an urgent need to identify the underlying molecular or genetic mechanism of this malignancy for better further medical management and patients` survival.

Background and objective: The assessment of human epidermal growth factor receptor 2 (HER2) status has become of great importance in the diagnosis of breast cancer. The aim of this study was to investigate the diagnostic value of quantitative Polymerase Chain Reaction (qPCR) and Chromogenic In Situ Hybridization (CISH) to assess HER2 status of biopsy specimens. Methods: To elucidate the status of HER2 gene amplification, biopsies of breast carcinoma from 120 patients with 2+ IHC status were analyzed by qPCR and CISH. Results: The results of the two experiments were compared, and it was depicted that the concordance rate between CISH and qPCR assays was 88.1%.The quantification of HER2 gene with CISH and qPCR showed that there was a significant correlation (p value= 0.0001 and r= 0.808). Conclusion: The results of this research support the idea that qPCR is a precise and reproducible technique, which can be employed as a supplementary method to evaluate HER2 status.

Background: Aggressive fibromatosis is a rare benign tumor with no potential for metastasis; however, its aggressive nature causes treatment failure and episodes of recurrence. There is no report from Iran about the treatment of this tumor, and all published articles are single-case reports, therefore in this study, we report our experience from two of the largest referral centers of the South of Iran. Methods: During five years (2007-2011), among more than 20000 surgical pathology specimens, 25 cases of fibromatosis were identified. Clinicopathologic findings were recorded for all of the cases, and follow up history according to the patients’ charts and direct contact by phone call were extracted. Results: There were 25 cases of fibromatosis, with female predominance, especially in the reproductive ages. All of the tumors had been located in the abdominal area, lower extremity, and head and neck area. Twenty-three cases had been operated for surgical excision. Fifteen cases had at least one episode of recurrence, mostly located in the abdominal area. No death or metastasis occurred. Conclusion: Clinicopathologic findings of desmoid tumor in Iran are very similar to other countries, however, there is still much controversy about the method of treatment for fibromatosis, and there are many challenges for patients, regarding multiple episodes of recurrence and the infiltrative aggressive nature of fibromatosis.

Background:Breast cancer remains the most common and second lethal cancer in females. HER-2/neu is one of the most important amplified oncogene in breast cancer. The amplification of HER-2 is correlated with decreased survival, metastasis, and early recurrence. The amplification of HER-2/neu gene and synthesis of the protein are reported in 10%-34% of breast cancer cases associated with tumor size, advanced tumor stage, high-grade tumor, young age at diagnosis, absence of steroid hormone receptor, and lymph node involvement. Methods: Fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC) methods are options to evaluate HER-2 expression. The current study aimed at identifying the correlation between FISH and real-time polymerase chain reaction (PCR) in measuring HER-2 expression. Results: The study investigated the performance of the real-time PCR as measured against FISH method in IHC +2 borderline cases. In a total of 120 IHC 2+ samples, 58.3% were negative and 41.6% positive for HER-2 gene, confirmed by FISH as a gold standard method. The real-time PCR ratio was HER-2 gene by FISH as a gold standard assay. Conclusion: Despite the fact that real-time PCR is a promising method to evaluate HER-2 over expression and a supplementary array to FISH, according to the results of the present study it cannot be utilized instead of gold standard techniques; therefore, additional studies should be carried out to appraise the value of this method to evaluate HER-2 over expression.

The oral cavity is uncommon site for metastatic disease usually discovered secondary to malignancy. We encountered with a rare case in which metastasis to mandibular bone was the first clinical sign in the diagnosis of breast cancer without any radiographic findings. A 49-yr-old premenopausal woman, was referred to the Department of Medical Oncology of Imam Hossein Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran in 2014, presented with pain and tenderness in the left mandibular and temporal bone and paresthesia of the lower left lip and chin. CT scan of mandible showed no significant finding. Four months later, she was referred with complaints left breast pain for 4 wk and worsening swelling, pain and paresthesia. Breast examination revealed a 2 cm firm nodule on the left breast. Based on her medical history and histopathological study, metastatic carcinoma of the breast was suspected. She has received chemoradiotherapy that led to complete relief of her symptoms and remission of the disease. In the presence of an ambiguous sign in oral cavity such as jaw pain or paresthesia, diagnostic examination of malignancy is recommended.
