Giant cell carcinoma of the endometrium is a rare and an aggressive tumor that should be distinguished from other endometrial tumors with a prominent giant cell component, including trophoblastic tumors, certain primary sarcomas, and malignant mixed müllerian tumors. At present, cumulative data on this rare histological variant is limited and the prognostic significance of the presence and the extent of a giant cell component in endometrial carcinoma remain uncertain. We report giant cell carcinoma of endometrium in an Indian female, which according to our best knowledge, is the first case being reported from Indian Subcontinent.

Background and Objective: Inflammatory pseudotumor is a lesion composed of proliferating spindle cells with mixed inflammatory infiltrates. Some authors have proposed the name inflammatory myofibroblastic tumor as a proper descriptive term rather than the vague inflammatory pseudotumor. The aim of this study was to verify the myofibroblastic origin of spindle cells in idiopathic orbital inflammatory pseudotumor by immunohistochemical staining. Materials and Methods: We reviewed a series of 32 inflammatory pseudotumors arising in orbit for expression of smooth muscle actin, vimentin, desmin and anaplastic lymphoma kinase using immunohistochemical staining. Results: There were 21 females and 11 males aged 3 to 64 years with a mean age of 31. Immunohistochemically, spindle cells of 51.75%, 79.3%, and 17.2% of lesions expressed smooth muscle actin (15/29), vimentin (23/29) and desmin (5/29). All lesions (32/32) were negative for anaplastic lymphoma kinase Conclusion: In this study, reactivity for smooth muscle actin in spindle cells can be demonstrated as myofibroblastic differentiation. The absence of anaplastic lymphoma expression in all cases of orbital inflammatory pseudotumor in this study strongly suggests that these lesions, albeit histologically similar, are biologically distinct from their soft tissue counterparts or those inflammatory myofibroblastic tumor that negative for anaplastic lymphoma immunoreactivity may be characterized by one or more chromosomal aberration involving regions other than 2p23 is as yet unknown.

Hydatid disease is endemic in some parts of the world. This disease can occur in any organ. We present a 22-year-old farmer who was suffering from hydatidosis for 4 years. He was admitted to the hospital because of fever, cough, and chest pain in 2004. A chest radiograph revealed multiple nodules in both of lungs. A transthoracic echocardiogram showed cystic lesion in the apex of right ventricle. IgG Ab ELISA for hydatid cyst was positive and albendazole was administrated. One year later, he was admitted to the hospital because of hemoptysis, a transthoracic lung biopsy was performed. Pathologic examination revealed laminated membrane of hydatid cyst in associated with fibrinoleukocytic exudates. Three years after the second admission, he was admitted to the hospital because of dyspnea. Iranian people especially who live in village need more information about the routes of prevention because therapy is difficult in some cases.

Follicular thyroid carcinoma (FTC) is the second most common type of thyroid cancer after papillary carcinoma. It usually grows slowly and is clinically indolent; but rarely, its aggressive forms with distant metastases can occur. We report here an uncommon case of bilateral orbital metastasis of FTC. A 70-year-old woman presented with bilateral exophtalmus and past medical history of thyroid nodule surgery 15 years ago. Radiologic evaluation showed massive bilateral orbital mass with extension to calvarium. Tumor decompressed and removed with the suction and curettage and the patient was treated with chemoradiotherapy after operation. Pathologic examination showed metastatic follicular thyroid carcinoma. Although orbital metastasis of follicular thyroid carcinoma is uncommon, FTC should be considered as a potential primary neoplasm in a patient with orbital mass

Ollier’s syndrome, a variant of multiple enchondromatosis, is a rare disease with an estimated prevalence of 1/100,000, characterized by multiple enchondromas, asymmetrically involving small bones of the hands and feet, especially the proximal phalanges. Intracranial enchondromas, such as those arising from the skull base are extremely rare. Herein, we report a 25-year-old female, known case of Ollier’s disease, presenting with right eyelid ptosis and visual disturbance. Brain MRI revealed a skull base tumour suspicious to enchondroma followed by trans-sphenoidal resection. Histologic examination of the excisional biopsy sample confirmed the diagnosis of enchondroma.

Background & Objective: Glioblastoma-multiforme is the high grade form of astrocytic tumors with a short survival time, which are the most common type of brain tumors. Therefore, finding new therapeutic options is essential. Cyclin D1 is expressed in some human malignancies and can be a potential target for therapeutic intervention. The aim of the present study was to determine this relationship. Methods: This is a cross-sectional study conducted in the pathology department of Al-Zahra Hospital in Isfahan, Iran. In this study, 100 samples diagnosed with astrocytic tumors between 2011 and 2015 that met the study’s requirements were studied and immunohistochemical staining for cyclin D1 was performed for each specimen. At the end, the relationship between the expression of cyclin D1 and various variables including tumor grades, tumor subtypes and patient demographic features were examined using appropriate statistical tests. Results: Of the 100 samples, cyclin D1 was positive in 60 samples and negative in 40 samples. Moreover, in 26 samples, the amount of the marker was low, while in 34 samples it was high. Following the results of the study, there was a significant difference (P =0.038) in the expression of the cyclin D1 marker among the four different grades of astrocytic tumors. Conclusion: The results showed that the expression of cyclin D1 was associated with different tumor grades, especially the high level of expression in grade 4, and the amount of cyclin D1 increased as the level of grade glioma increased.

Background & objective: Pruritus is the most frequent chronic dermal complication of sulfur mustard (SM), which negatively influences the quality of life. Exact pathophysiology of SM-induced itching is unknown. The current study aimed at evaluating the possible association between SM-induced itching and the serum levels of matrix metalloproteinase (MMP)-9 and their endogenous inhibitors, and serum levels of soluble forms of selectins (sL-, sP-, and sE-selectins) as adhesion molecules involved in the development of different inflammatory reactions. Methods: Serum levels of MMP-9, MMP-9/ tissue inhibitors of metalloproteinases (TIMPs), and selectins were measured by the enzyme-linked immunosorbent assay (ELISA), and compared between the groups (n=368) with and without itching, and matched control groups (n=126). Results: Serum levels of MMP-9 were significantly higher in the SM exposed group with itching, compared with that of the group without itching (medians: 894 and 624 pg/mL respectively; P-value =0.034). There was no relationship between the serum levels of MMP-9/TIMP-1, MMP-9/TIMP-2, MMP-9/TIMP-4, and itching in the patients exposed to SM. Median serum levels of sE- and sL-selectins in the exposed group with itching were higher than those of the exposed group without itching. These differences were statistically insignificant (P-values =0.084 and 0.095, respectively). Conclusion: According to the results of the current study, the increased serum levels of MMP-9 and selectins 20 years after exposure may play role in the pathogenesis and persistence of SM-induced itching in the exposed individuals.

Hydatid disease, caused by larval stage of Echinococcus granulosus, is a common parasitic infection of human and animal. Although liver and lung are the most commonly affected area, hydatid cyst may develop any part of the body. Primary subcutaneous hydatid cyst is extremely rare. We report a case of 54 years old man who presented with palpable mass in scapular region from 3 years ago. Present and past medical history was not significant finding. Pathologic evaluation identified the cystic structure as unilocular hydatid cyst. Primary hydatid disease constitutes a potentially serious differential diagnosis of any subcutaneous mass in endemic area of hydatid disease.

Proliferating pilomatricoma is a distinctive rare variant of pilomatricoma first described in 1997.Very few cases of proliferating pilomatricoma have been reported in the literature until date. This report is a case of 65 years old male presenting with hard nodular lump on the right side of neck slowly increasing in size for the last 8 months. Wide excision of the lump was performed with clear surgical margins. Histopathology revealed a tumor mass composed of lobular proliferation of basaloid cells in association with adjacent focal areas containing cornified material with shadow cells. Variable nuclear atypia and scattered mitotic activity was noted in basaloid cells, so a final diagnosis of proliferating pilomatricoma was rendered. This report herein reviews histopathological features of this rare entity.

Primary ovarian carcinoid tumors of the ovary are rare and represent less than 0.1% of ovarian malignancy. One of its subtypes is the strumal carcinoid in which the thyroid tissue is seen in intimate association with carcinoid tumor. We here report a 47-year-old woman with strumal carcinoid of the right ovary presented with cessation of menstrual periods in the past 3 months and was referred due to a possible menopause-related symptom. A firm pelvic mass was found in physical examination and a large mass (20 × 15 × 8 cm) in the right ovary was reported in ultrasound evaluation. The spiral CT scan reported masses in both ovaries. The patient underwent total abdominal hysterectomy plus bilateral salpingo-oophorectomy. The pathological evaluation revealed strumal carcinoid tumor with thyroid tissue in right ovary and benign cystic teratoma in left ovary. Our case was alive at 8 years after the operation with no disease recurrence.

Background & Objective: Vibrio cholerae is a natural inhabitant of the environment and causes severe diarrhea ailments (cholera) that affects thousands of people each year worldwide. The most important virulence factors of this pathogen are cholera toxin (cholera toxin CT) and Type IV pili (toxin co-regulated pili TCP), which are encoded within the genome of the filamentous bacteriophage CTXφ. In the present study, according to researchers’ report on genotypic variations of cholera toxin, we evaluated the sequence of ctxB subunit obtained from 100 strains of patients infected with cholera in Iran. Methods: The evaluation of genotype variations of cholera toxin was made by high-resolution melting curve analysis illustrating a single nucleotide change. Then, ctxB gene sequencing was performed. Through this analysis and the sequencing process, two standard samples were studied. Results: Using serologic tests, all the strains analyzed in this study were identified to be in O1 serotype. However, there have been differences in sequences of ctxB as some were similar to V. cholerae O1 biovar El Tor str. N16961 while others were similar to the genotype of V. cholerae ATCC 14035. We did not observe any particular pattern within the process of mutation. Conclusion: The analysis of the new samples of ctxB showed that they were potentially different. It seems that these complicated species were affected by a new genetic exchange of El Tor and classic genotypes.

Background & Objective: Some of the patients with myelodysplastic syndrome (MDS) are categorized as good prognosis based on the Revised International Prognostic Scoring System (IPSS-R). However, these patients may have poor clinical outcomes. It seems that the current diagnostic tools and IPSS-R cannot consider genetic factors for determining the prognosis of MDS patients.Methods: This cross-sectional study included all adult MDS patients of both genders who were admitted from March 2015 to March 2020 to the Hematology wards of two educational tertiary hospitals in Iran (Namazi and Faghihi, affiliated with Shiraz University of Medical Sciences). Study data included relevant retrospective data from medical records and the results of immunohistochemical p53 staining on bone marrow biopsies.Results: Of the 84 patients, 65 (77.4%) showed p53 expression in bone marrow. They had shorter median survival than those without p53 expression. Considering both variables of P53 IHC results and IPSS-R score, the patients who died with low-risk IPSS-R score presented high p53 expression.Conclusion: This study shows that the investigation of p53 expression by IHC at the time of diagnosis is a valuable indicator of survival rate in MDS patients. These data suggest that the immunohistochemical analysis of p53 can be a prognostic tool for MDS and should be used as an adjunct test to make decisions on the best therapeutic choice.

Background & Objective: Diabetic foot ulcer (DFU), is one of the most frequent causes for hospitalizations in patients with diabetes. A major problem in the treatment of DFU is the increased-incidence of methicillin-resistant Staphylococcus aureus (MRSA). The aim of this study was to determine the SCCmec types of MRSA isolates and their epidemiology among patients with diabetes. Methods: This study was carried out on 145 diabetic patients with DFUs. The antibiotic susceptibility tests (ASTs) were performed using the disk diffusion method and E-test technique. SCCmec typing was done by multiplex PCR. Moreover, the presence of virulence toxin genes, including pvl and lukED was detected by PCR assay. Result: In 145 samples from which S. aureus was predominantly isolated, 19.48% were MRSA. Analysis of MRSA isolates revealed that the most prevalent SCCmec type was type IV (46.7%) followed by type III (30.0%) and type V (20.0%). One strain (3.3%) was untypeable. The prevalence of pvl and lukED was 56.7% and 100%, respectively. Conclusion: The high prevalence of MRSA in DFUs represents the high levels of antibiotic usage among patients with diabetes. In this study, resistance to other important clinical antibiotics was detected among MRSA isolates. The high proportion of SCCmec type IV and V strains, even in former hospitalized patients, indicates the entrance of these clones to the clinical setting.

Background and Objective: Primary fallopian tube carcinomas (PFTC) are rare tumors with non-specific clinical presentations. The current case was unique since the tumor was first detected on endometrial curettage and clinicoradiologically was misdiagnosed as endometrial carcinoma.Case Report: A 48-year-old, post-menopausal female presented with one episode of vaginal bleeding. Endometrial curettage showed poorly differentiated carcinoma, while cervico-vaginal Papanicolaou (Pap) smear was negative for malignant cells. Right sided fallopian tube carcinoma in-situ was diagnosed on histopathological examination of surgical hysterectomy with B/L salpingo-oophorectomy specimen. Conclusion: As observed in the current case, unusual tumor histology with broad papillary fronds lined by pleomorphic cells showing nuclear stratification and focal involvement of endometrial curettage specimen may be considered a useful pointer for tubal malignancy.

Background: Delayed graft function is a main complication after deceased donor kidney transplantation that adversely affects graft outcome. Difficulties in prediction and early detection of delayed graft function have hindered the ability to perform proper therapeutic interventions. We investigated whether measuring urinary interleukin 18 and neutrophil gelatinase-associated lipocalin as markers of ischemia reperfusion injury could predict delayed graft function in deceased donor kidney transplant patients. Methods: We studied 69 patients undergoing kidney transplantation from deceased donor during early October 2013 to December 2014 at the Urology Research Center, Sina Hospital, Tehran University of Medical Sciences, Tehran, Iran. Serial urine samples at 2, 24, and 48 h after transplantation were analyzed for interleukin 18 and neutrophil gelatinase-associated lipocalin levels. Results: Thirteen patients (18.9%) developed delayed graft function. Urine interleukin 18 to urine creatinine ratio was significantly higher in patients with delayed graft function compared to those with non-delayed graft function, at 2 (P=0.003), 24 (P<0.001) and 48 h (P=0.018) points. The levels of neutrophil gelatinase-associated lipocalin to urine creatinine ratio were significantly higher in the group with delayed graft function at the 24 (P=0.004) and 48 h (P=0.015) points. The receiver–operating characteristic curve analysis suggested that both urinary biomarkers at 24 h after transplantation had better accuracies for prediction of delayed graft function. In multivariate analysis, only urinary interleukin 18 to urine creatinine ratio improved the ability of clinical model for predicting delayed graft function. Conclusion: Urinary interleukin 18 to urine creatinine ratio at 24 h post-transplantation, along with traditional markers such as relative fall in serum creatinine, urine output and other risk factors for delayed graft function, increased the ability to predict delayed graft function.

Background & objective: Beta-lactam antibiotics resistance specifically Imipenem and Meropenem, the last choices of treatment, causes fatal events in patients with P.aeruginosa infection. The aim of this study was to detect the VIM and IMP of metallo-beta-lactamase genes in 103 isolates of P. aeruginosa in two Iranian hospitals. Methods: In this study, we evaluated the susceptibility of P. aeruginosa to a range of β-lactam antibiotics using disk diffusion method as a standard biochemical test. Combined disk test of Imipenem (IMP) and Imipenem plus Ethylenediaminetetraacetic acid (EDTA) was performed as a phenotypic method to find metallo-beta-lactamase producing isolates.Using conventional PCR method; we evaluated VIM and IMP of metallo-beta-lactamase (MBL) genes in 103 isolates of P.aeruginosa. Results: Twenty six (25.2%) out of 103 isolates were resistant to Imipenem and 26 (25.2%) to Meropenem. Among 26 Imipenem and Meropenem-resistant strains (25.2%), 19 cases (73.0%) were MBL producing. Using PCR method, we detected the blaVIM and blaIMP genes in 6 (5.8%) and 2(1.9%) of 19 MBL producing isolates, respectively. Conclusions: Evaluation of these carbepenemases genes improve epidemiologic researches and also, can be used as a diagnostic tool for discriminating between antibiotics resistant and sensitive strains of P.aeruginosa as well as follow-up the patients after treatment.

Background and Objective: In recent years, due to increasing number of patients with non-healing skin ulcers, skin substitutes have been used. Skin substitutes contain living cells causing faster and more effective wound healing. Therefore, research on the use of autologous and allogeneic cells such as fibroblasts in skin substitutes has attracted attentions. However, there are discrepancies in the immune responses to allogeneic fibroblasts. Therefore, we aimed to review the immune responses to allogeneic fibroblasts.Methods: Donor fibroblasts were isolated from the skin of three rats. Nine recipient rats which were subcutaneously injected with three different regimens, were divided into three groups: Group 1; phosphate buffered saline (PBS) without cells (control), group 2: allogeneic fibroblasts of one animal source suspended in phosphate buffered saline, and group 3; phosphate buffered saline containing mixed allogeneic fibroblasts of three animal sources. The skin samples were biopsied at 1, 3 and 7 days after injection and studied histopathologically. Results and Conclusion: No signs of redness and edema were observed in the injection sites. In pathology examination, changes such as vasculitis, eosinophils and lymphocytes accumulation around fibroblasts, fibroblast apoptosis and transplant rejection at the injection site were not observed in either group.Subcutaneous injection of allogeneic fibroblasts in rats can be introduced as a promising approach for wound healing as they do not stimulate the immune system.
