    Mesonephric adenocarcinoma of the uterine cervix is an extremely rare tumor of the female genital tract which derives from the remnants of embryonic mesonephric ducts and its prognosis, diagnosis and treatment is rather challenging. We report a case of a 46-year-old woman with history of abnormal uterine bleeding and an enlarged uterine cervix on physical examination without obvious mass lesion. She was clinically underdiagnosed with cervical myoma and mesonephric hyperplasia. After simple hysterectomy, stage IB2 mesonephric adenocarcinoma was diagnosed. Despite adjuvant chemoradiation, she presented with peritoneal and locoregional recurrence in less than a year. So, in the presence of abnormal bleeding and cervical mass, mesonephric hyperplasia in cervical biopsy specimen should be suspected for adenocarcinoma. Radical hysterectomy and complete staging with or without salpingo-oophorectomy is the mainstay of treatment. Despite all ambiguities, due to the small number of reported cases, the overall prognosis seems to be less favorable than conventional cervical adenocarcinoma.

    Chondroma is a benign cartilaginous tumor. It is found very rarely in the head and neck.

    This report describes a 25-year-old woman who presented with generalized headache from 4 months ago. The patient underwent excisional surgery. The histological examinations revealed benign cartilage forming tumor, compatible with chondroma. The radiologic and histologic correlation confirmed the diagnosis. Based on the diagnosis, the patient received no more treatment.

    We concluded that intracranial chondroma should be included in the differential diagnosis of a calcified masson skull imaging. Proper diagnosis is necessary for further patient management.

    Polyomavirus-associated nephropathy (PVAN), mainly caused by the BK virus, is one of the most important infectious complications of kidney transplantation. The leading histopathologic characteristics of PVAN is viral cytopathic effects, such as nucleomegaly with smudged or clumped chromatin and intranuclear ground-glass inclusion, mostly in tubular epithelial cells. Moreover, tubular necrosis, tubulitis, interstitial inflammation, atrophy, and fibrosis have been noted. Positive immunohistochemistry (IHC) staining for SV-40 highlights the infected epithelial cells of renal tubules.

    A total of 85 core needle biopsies of transplanted kidneys were evaluated histologically and were stained for SV-40 using the IHC method. In addition, a follow-up of graft failure was performed.

    Our findings revealed that the frequency of polyomavirus infection in kidney transplant patients in the Northeast of Iran is 4.7%. There was no significant correlation between PVAN and graft rejection. Although a higher rate of graft loss was observed in PVAN patients, in comparison with non-PVAN patients (25% vs. 14.8%), the difference was not statistically significant. Moreover, patients with immunohistochemically confirmed PVAN and those with histopathologic features of viral-like cytopathic effects had significantly lower graft survival in the follow-up period (42.5 vs. 196.8 months and 109.4 vs. 205.7 months, respectively).

    The frequency of polyomavirus infection in kidney transplant patients in the Northeast of Iran is 4.7%. There was no significant correlation between PVAN and graft rejection. Furthermore, we observed that polyomavirus infection accelerates the course of graft loss.

    olorectal Cancer (CRC) is the third most common cancer after prostate (breast in women) and lung cancer; it is also the third cause of cancer deaths reported in both men and women in 2020. Currently, the most commonly used diagnostic tools for CRC are colonoscopy, serological methods, and other imaging techniques. Despite the benefits and abilities of these methods, each of them has disadvantages that reduce its functionality and acceptance. The aim of this study was identifying specific and non-invasive genetic biomarkers to diagnose colorectal cancer.

    In this study, changes in the expression of

    and

    genes were evaluated by Real Time PCR in blood and tissue samples of CRC patients. A total of 100 samples (50 Blood and 50 Tissue samples) were evaluated with a definite diagnosis of CRC in Firoozgar Hspital, Tehran, Iran, in 2018. The QPCR method was used to compare the expression of candidate genes between the patients group and control group in both samples. Sensitivity and specificity of the test were examined using ROC curve analysis.

    The results showed a significant down-regulation in the expression of both selected genes in tissue and peripheral blood in the various stages of the CRC. The sensitivity and specifity of both genes was about 80%.

    The findings showed that the two candidate genes can be suggested as specific biomarkers for diagnosis of CRC using the peripheral blood as a non-invasive method. For a definite conclusion, more research is needed.

    Galectin-8 has relationships with cell growth and metastasis of some cancers. Due to controversy in the clinical significance of this protein in the cancer process, we investigated its roles in the development of head and neck squamous cell carcinoma.

    This study was performed on 93 samples of patients with Squamous Cell Carcinoma or dysplasia of the head and neck, who underwent biopsy or surgery from 2015 till 2017 in Boo-Ali SINA hospital of Sari, Iran. The relevant paraffin embedded tissue blocks were obtained from archive of pathology and evaluated for galectin-8 by immunohistochemistry. The association between expression of galactin-8 and age, sex, location and stage of disease were assessed. selleck inhibitor To compare expression rate between the groups, Mc-Nemar, Chi-square and Fisher’s exact tests were used. The P-value<0.05 was considered significant.

    Strong cytoplasmic and nuclear galactin-8 staining was observed in 97.6% cases of normal tissues while 77% of dysplastic lesions and 69% of the cancers revealed negative immunoreactivity.
