salivary gland tumors accounts for less than 1% of all tumors. minor salivary gland tumors (msgts) are uncommon and make up about 10% of all salivary gland neoplasms. the clinical and histopathological distribution of these tumors vary geographically. a case of a 38 yr old man with a minor salivary gland mass at chin region isreported here. the tumor invaded into the anterior surf...
background: non-melanoma skin cancer is the most common malignant tumor in humans. the role of ultraviolet radiation is well-known in the pathogenesis of basal cell carcinoma (bcc) and squamous cell carcinoma (scc). cd10 is a zinc-dependent metallopeptidase known as common acute lymphoblastic leukemia antigen (calla). although cd10 expression has been investigated in some cutaneous tumors, to o...
INTRODUCTION Hepatic sclerosing hemangioma is a very rare benign tumor, characterized by fibrosis and hyalinization occurring in association with degeneration of a hepatic cavernous hemangioma. We report here a rare case of multiple hepatic sclerosing hemangioma mimicking metastatic liver tumor that was successfully treated using laparoscopic surgery. PRESENTATION OF CASE A 67-year-old woman ...
OBJECTIVE A rare subtype of meningioma, sclerosing meningioma is not included in the current World Health Organization classification of meningiomas and is classified into the category of other morphological variation subtypes. Sclerosing meningioma is often misdiagnosed to other non-benign meningioma or malignant neoplasm, so it is important to diagnose sclerosing type correctly. We analyzed t...

BACKGROUND Cholangiocarcinoma is a frequent complication of primary sclerosing cholangitis and is a leading cause of mortality in patients with this disease. The tumor suppressor gene p16 is commonly inactivated in many neoplasms; however, the role of p16 in the pathogenesis of cholangiocarcinoma is unclear. Therefore, we examined the role of p16 inactivation in the pathogenesis of cholangiocar...
Pulmonary sclerosing hemangioma (PSH) is a benign tumor with two cell populations (epithelial and stromal cells), for which genomic profiles remain unknown. We conducted exome sequencing of 44 PSHs and identified recurrent somatic mutations of AKT1 (43.2%) and β-catenin (4.5%). We used a second subset of 24 PSHs to confirm the high frequency of AKT1 mutations (overall 31/68, 45.6%; p.E17K, 33.8...
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...
