Serratia marcescens (S.M) is a species of gram–negative bacteria in the family enterobacteriaceae. A human pathogen, S. marcescens is involved in nosocomial infections, particularly in urinary tract and wound infections. This report describes a 63 years-old man that referred to hospital with dyspnea FC IV and he underwent cardiac valves replacement surgery with a diagnosis of severe mitral stenosis (M.S), severe tricuspid regurgitation (T.R), and moderate aortic insufficiency (A.I). Five days after operation, he presented with 40 °C fever, respiratory distress, elevation of liver enzymes, and decreased consciousness. Sepsis work up showed positive blood culture for Serratia marcescens. Despite therapy, he died due to Serratia marcescens endocarditis and mediastinitis. Positive blood culture for Serratia marcescens is very rare but it should be considered in post operation patients after cardiac valve replacement presenting with fever. Besides, prevention of endocarditis due to Serratia marcescens should be observed.

Localized Leishmania Lymphadenitis (L.L.L) is a self limited clinical presentation of cutaneous leishmaniasis. Microscopic findings in L.L.L are very similar to Toxoplasma lymphasenitis. In all cases, an intensive microscopic search should be done for Leishman bodies. In this study, we describe our microscopic findings and results of our immnohistochemical (IHC) study with a panel of monoclonal antibodies against T-Cells, B-Cells, histiocytes, Langerhans cells, and dendritic reticulum cells. Morphologic and immunohistochemical study in this case showed expanded paracortical tissue with many small clusters of epithelioid histiocytes and large reactive B follicles. Immature sinus histiocytosis in subcapsular and trabecular sinuses was also seen.

The gastric inflammatory fibroid polyp (IFP) is a rare benign tumor of unknown etiology that is localized mainly in the antrum and presents endoscopically as submucosal mass. The lesion manifests as abdominal pain, weight loss, bleeding, dyspeptic symptoms, and iron deficiency anemia. We report a case of gastric IFP presented with microcytic anaemia, dyspepsia, malena and weight loss. Endoscopy revealed presence of a sessile gastric antral polyp. A clinical diagnosis of gastric malignant polyp was suspected. Microscopic examination revealed the presence of mononuclear fusiform fibroblast like cells, arranged in fascicles and whorl formation around vessels, in an inflammatory background rich in eosinophils. The fusiform cells appeared uniform and had abundant cytoplasm with pale spindle shaped nuclei. We highlight the case because of its rarity amongst the different types of gastrointestinal polyps and its unusual presentation like anaemia and weight loss with clinical suspicion of malignant gastric polyp.

Thymoma is a term that should be restricted to neoplasms of thymic epithelial cells, irrespective of the presence or the number of lymphocytes. The usual location of thymoma is the antrosuperior mediastinum; however, this tumor can also occur in other mediastinal compartments, in the neck, within the thyroid gland, in the pericardial cavity, the pulmonary hilum, within the lung parenchyma, or the pleura itself (sometimes coating it in a mesothelioma-like fashion). The association of thymoma with hypogammaglobulinemia, Mucocutaneous candidiasis, systemic lupus erythematosus and myasthenia gravis is well known. Here we present a patient admitted in our hospital with buttock rashes regarded to be zoster of the buttock. In his past medical history he had recurrent cutaneous infections, lupus erythematosus, hypergammaglobulinemia, recurrent oral candidiasis and B- cell dysfunction. During the patient evaluation, a mass was found in the mediastinum and percutaneous needle biopsy confirmed the diagnosis of thymoma(type B3). This is the second case reported having thymoma in association with hypergammaglobulinema.

Background and Objectives: Laboratory reference values are an important tool for clinical management of patients. Reference values being used in most laboratories in Iran have been provided from the established reference values from developed countries. However, several variables can affect on these laboratory parameters. Therefore, this study was carried out to establish the reference values of hematological parameters in the blood donors of central province of Iran as a general population.
Methods: Blood samples of 1100 male blood donors were collected consecutively from Blood Transfusion Organization. Complete blood cell (CBC) count in 2012 and differential was performed using an automated hematology analyzer.
Results: The median and 95% reference values (2.5th-97.5th) for Hb and platelet counts were 15.5 g/dl (14.1-17.7) and 209 ×109 cells/L (151-322) respectively. The median for total WBC count, neutrophil, lymphocyte, monocyte and eosinophil were 6.7 ×109 cells/L (4.3-11.2), %58 (%50-%70), 40% (30-49%), 0% (0-2) and %1 (0-3%), respectively.
Conclusion: The hematological profile of the population in central province of Iran was different from the reports of other countries and also the standards reference ranges described in textbook. So, further nationwide study should be carried out to establish the hematological reference values of the Iranian population as a whole.

Splenogonadal fusion is a rare entity with approximately 150 reported cases until the year 2005. The entity is a rare congenital anomaly in which there is fusion of splenic and gonadal anlagen or mesonephric derivatives. Splenogonadal fusion has two continuous and discontinuous types. About ten cases have been reported to be associated with bilateral cryptorchidism in literature. Very few cases have been diagnosed preoperatively. Many cases present as a testicular swelling and undergo an unnecessary orchiectomy with the suspicion of a testicular neoplasm. Herein, we report a new case of discontinuous splenogonadal fusion in a 29 years old man with bilateral cryptorchidism who underwent surgery. Surprisingly two masses were noted adjacent to undescendent testis in left groin in operative room which were resected and proved to be a new case of splenogonadal fusion in histological exam.

One of the unusual variant of ovarian tumor is sex cord stromal tumor with annular tubules (SCTAT). The recurrence in case of malignant ovarian SCTAT ranges from 3mo to 20yr. This report describes the case of recurrence of SCTAT in a 35yr old woman after 4yr of hysterectomy with bilateral salphingo-Oopherectomy. Microscopic examination revealed features of SCTAT. Because of its unusual behavior evidenced by delayed recurrence in spite of bland cellular features, proper long term follow–up is essential.

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.

Background & Objective: Toxoplasma gondii infection has public health importance and can lead to serious diseases in immunosuppressed patients, such as HIV cases. Appropriate control of T. gondii infection in HIV patients requires information about the prevalence of T. gondii antibodies and DNA in different population. In this study, we aimed to determine the prevalence of Toxoplasma gondii antibodies and DNA in HIV patients in Tehran, Iran.Methods: A total of 149 HIV patients from the Iranian Research Center for HIV/AIDS, Tehran, Iran were enrolled in the study. Anti-Toxoplasma IgG and IgM were detected by ELISA and T. gondii DNA was evaluated by PCR and quantitative real-time PCR. IgG positive samples were also assessed for their avidity. Results: Anti-Toxoplasma IgG and IgM were positive in 46.3% and 2.7% of cases respectively. 92.7% of our patients showed past infection and 4.3% revealed recently acquired toxoplasmosis based on their IgG avidity test. T. gondii DNA was not detected by PCR but real-time PCR results showed DNA in 4.7% of total patients and 13.1% of the IgG seropositive cases.Conclusion: Our findings indicated that latent toxoplasmosis was relatively prevalent in our study population, but new T. gondii infection had low prevalence. Almost half of our patients were IgG negative and at risk of acquiring toxoplasma infection. Low copy numbers of DNA were detected in 4.7% of the cases without any clinical manifestation. Therefore, detection and monitoring of anti-Toxoplasma antibodies and DNA in HIV patients is substantial to estimate the risk of reactivation and new infection.

Background & Objective: Bladder cancer is the fourth most common cancer in men and the most common cancer in women, comprising 8% of all males and 3% of female tumors. The present study aimed to estimate the five-year survival rates of bladder cancer in Iran.Methods: Information on3,337 registered cases of bladder cancer was obtained from the Office of National Cancer Registry in the Ministry of Health and Medical Education (MOH & ME). A telephone survey was conducted to gather additional information, such as survival status, demographic, and clinical profile. Kaplan–Meier estimates of five-year survival rates were calculated according to the age of diagnosis, gender, pathological type, and provincial pole.Results and Conclusion: Overall five-year survival rate was 77%. According to the pathologic type, five-year survival rates were 81%, 66%, 81%, 42%, 77%, and 82% in low-grade urothelial carcinoma, high-grade urothelial carcinoma, adenocarcinoma, undifferentiated carcinomas, Squamous Cell Carcinomas (SCCs), and other tumors, respectively. Additionally, those tumors were 93%, 88%, 81%, 64%, and 44% among patients whose average ages at diagnosis were < 50, 50–59, 60–59, 70–79, and > 80 years old, respectively. Our study revealed that age and histological type were the major prognostic factors for survival in patients with bladder cancer. Therefore, given the histologic features of the tumor and patients with advanced age, a continuous screening would be highly warranted.

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: Nodular hidradenoma or clear cell hidradenoma is a rare adnexal tumor arising from the eccrine glands. Case Report: A 60-year old female presented to the surgical out-patient clinic with complaints of breast lump of one year duration. Fine needle aspirate (FNA) of the lump yielded fluidly aspirate mixed with hemorrhage. On Giemsa-stained smears, a possibility of benign cystic lesion was considered. A provisional diagnosis of nodular hidradenoma was made. Additional sections were taken to rule out another component which revealed no other cell type. Periodic Acid Schiff’s (PAS) stain showed diastase sensitive positivity in the cytoplasm of tumor cells. The tumor cells were negative for estrogen and progesterone receptor but were positive for smooth muscle antigen, confirming the final diagnosis of nodular hidradenoma. Conclusion: To conclude, awareness amongst both the clinicians and pathologists for the possibility of diagnosing NH is mandatory and it should always be kept as differential diagnoses in the tumors of nipple and subareolar region to avoid unwarranted mastectomy and lymph node dissection.

Background & Objective: Bladder carcinoma ranks second in prevalence among males in Egypt. As a family of tyrosine kinases, fibroblast growth factor receptor (FGFR) dysregulation has been linked to some malignancies in humans. The aim of this study is to analyze the clinicopathological data of patients while investigating FGFR2 and FGFR3 immunohistochemical expression in invasive urothelial bladder carcinoma.Methods: This retrospective cross-sectional study included 60 invasive urothelial carcinoma (UC) cases in the Pathology department, Faculty of Medicine, Menoufia University, from 2009 to 2020. All biopsies were stained for FGFR2 and FGFR3 antibodies. Complete clinical data were available for 44 patients treated and followed in clinical oncology and nuclear medicine departments.Results: Advanced stage and high grade are significantly correlated with FGFR2 positivity (P=0.048 and 0.044, respectively). Cases presented with Perineural invasion showed a higher percentage of FGFR2 (P=0.023). There is a significant indirect linear correlation between FGFR3 expression and lymph node positivity (r= -0.265, P=0.041).Conclusion: High FGFR2 expression was associated with poor prognostic parameters, while high FGFR3 expression was associated with good prognostic parameters, and this might highlight the importance of FGFR-targeted therapy as FGFR2 antagonist and FGFR3 agonist for the treatment of urothelial carcinoma patients.

Background & Objective: This study was designed to determine the prevalence of serotypes, virulence-associated genes, and antimicrobial resistance of Streptococcus agalactiae in pregnant volunteers attending a major maternity hospital in Iran.Methods: The virulence determinants and antimicrobial resistance profiles of 270 Group B streptococcus (GBS) samples were assessed in the adult participants. The prevalence of GBS serotypes, virulence-associated genes, and antimicrobial resistance of the isolates was determined.Results: The GBS prevalence in the vaginal, rectal, and urinal carrier rates were 8.9%, 4.44%, and 4.44%, respectively, with no concomitant colonization. The serotypes Ia, Ib, and II were at a 1:2:1 ratio. The rectal isolates, harboring CylE, lmb, and bca genes, were of serotype Ia, susceptible to vancomycin. The serotype Ib from urine samples carrying three distinct virulence genes was susceptible to Ampicillin. In comparison, the same serotype with two virulence genes of CylE and lmb exhibited sensitivity to both Ampicillin and Ceftriaxone. The vaginal isolates belonged to serotype II with the CylE gene or serotype Ib with CylE and lmb genes. These isolates harboring the CylE gene were resistant to Cefotaxime. The overall antibiotic susceptibility range was 12.5-56.25%.Conclusion: The findings broaden our understanding of the pathogenicity of the prevailing GBS colonization and predict different clinical outcomes.

Muscle tissue, skeletal muscle as well as cardiac muscle, is commonly affected in mitochondrial disorders. One explanation for this observation is that muscle tissue has a high-energy demand and therefore is more sensitive to a deficiency of mitochondrial energy production than some other tissues. In mitochondrial disorders, skeletal muscle tissue may be affected primarily by defective respiratory chain function or secondarily to peripheral neuropathy with neurogenic muscle atrophy. The clinical manifestations of mitochondrial myopathies are variable and include muscle weakness, exercise induced cramps ad myalgia. Also, ptosis and progressive external ophtalmoplegia are typical but not obligate finding. Hereby we wanted to report a case of mitochondrial myopathy, diagnosed by histochemical and electron microscopic studies for the first time in Iran. Our case was a 12-years old girl who referred due to muscle weakness to our center which started at an age of 8 years. Later, she also developed ptosis. EMG studies were inclusive and muscle biopsy revealed typical red ragged fibers with special staining. By electron microscopy, typical mitochondrial changes were detected.

Ovarian borderline serous tumors are uncommon. Combination of borderline serous adenofibromatous tumor and prominent micro papillary architecture is not previously reported. We report a case of borderline papillary serous adenofibromatous tumor (also called serous adenocarcinofibroma) with extensive micropapillary pattern in a 27 year-old married woman. She was infertile and presented with diffuse abdominal pain and dysparonia. Bilateral 5.3 and 4.5 cm solid ovarian masses were detected by sonography. Both masses were ovoid with tan-pink bosselated smooth external surfaces, and solid tan lobular cut surfaces. Microscopically, both tumors showed many papillary structures in a fibrotic stroma and contained multiple psammoma bodies. The papillae had broad hyalinized fibrotic stroma with many micropapillary projections arising from the main papilla, lined by mildly pleomorphic cuboidal cells. Mitotic activity was low with no marked nuclear atypia or stromal invasion. No extraovarian implants or metastases were identified.

Primitive neuroectodermal tumor (PENETs) is an uncommon malignancy of bone and soft tissue witch rarely occurs in the kidney. In more than 90% of the cases, the tumor cells relieves a balanced translocation (11; 22) (q24; q12). Immunohistochemical staining may be required for diagnosis of PENET. The cells of tumor express CD99, vimentin, NSE, FL1 but do not express Ck, LCA, myogenin, and WT1. We present a 36-year –old female with left –side tender abdominal swelling, and history of trauma to abdominal. CT imaging confirmed a huge solid mass of kidney, also extending into renal pelvis. Histological section of the lesion showed a malignant proliferation of small round cells in rosette-like pattern with foci of necrosis area. Tumor cells expressed high level of CD 99 antigen. The diagnosis of the lesion was primitive neuroectodermal tumors (PNET). Following-up after 6 months showed no recurrence.
