Granular cell tumors are benign subcutaneous or submucosal lesions of neurogenic origin. In this case study one patient was diagnosed and treated successfully with complete surgical resection of a laryngeal granular cell tumor that was originated from the left arytenoid region that very rare location. There is no evidence of recurrence 2 years after surgery. Granular cell tumors should be consi...

leydig stromal cell tumor is a rare ovarian tumor that belongs to the group of sex-cord stromal tumors. they produce testosterone leading to hyperandrogenism. we present a 41yr old woman with symptoms of virilization and a mass of right adenex via ultra sonography, and a rise of total and free serum testosterone. an ovarian source of androgen was suspected and a surgery performed. a diagnosis o...

Understanding tumor heterogeneity is an urgent and unmet need in cancer research. In this study, we used a morphology-based optical cell separation process to classify a heterogeneous cancer cell population into characteristic subpopulations. To classify the cell subpopulations, we assessed their morphology in hydrogel, a three-dimensional culture environment that induces morphological changes ...

Congenital granular cell epulis is a rare benign soft tissue lesion arising from the alveolar ridge in neonates. A rare case of multiple congenital granular cell epulis is reported, alongside a description of its vascular immunohistochemical profile. A female newborn presented with two exophytic pedunculated red nodules located on the alveolar ridge between the future eruption sites of the inci...

most popular sources for electromagnetic waves. However, there are many concerns regarding their biological effects on the body, especially the central nervous system. Therefore, the aim of this study was to evaluate the effects of cell phone radiation on histology of the cerebellar granular cells in the neonatal rat. Materials and methods: We selected some Wistar rats. Then, we randomly d...

Granular cell tumors (GCT) are rare benign tumors. Less than 1% of GCTs involve the extrahepatic biliary tree. Most researches favour a Schwann cell origin. Patient, caucasion, female, 31-year-old presented with 4 month history of painless jaundice and pruritus. US and CT revealed dilatation of intrahepatic biliary tree and surgery was performed. Firm tumor mass was found above the conjunction ...

The granular cell tumor is an uncommon tumor that usually appears as a solitary small nodular growth and runs a benign course. It occurs widely throughout the body, but is rarely described in the abdominal wall. The authors report a case of malignant granular cell tumor which was arising in anterior abdominal wall of a 67-year-old woman. Malignant variant is rare and the abdominal wall site is ...
