Basal Cell Adenocarcinoma Ex Pleomorphic Adenoma
Basal cell adenocarcinoma (BCAC), a salivary gland tumor, has been theorized to originate either from monomorphic adenomas undergoing a malignant transformation or to arise de novo. Here we present the first case report of a BCAC tumor that arose within a pleomorphic adenoma.
متن کاملimmunohistochemical analysis of b-cell lymphoma -2 in pleomorphic adenoma and mucoepidermoid carcinoma
background: salivary gland tumors form a major area in the field of oral pathology. b-cell lymphoma -2 (bcl-2) is an anti-apoptotic gene with up-regulation in various neoplasms. the aim of the present case-control study was to comparatively investigate the expression of bcl-2 protein in pleomorphic adenoma (pa) and mucoepidermoid carcinoma (mec) and assess its potential diagnostic role in diffe...
متن کاملImmunohistochemical Expression of p53 in Pleomorphic Adenoma and Carcinoma Ex Pleomorphic Adenoma
OBJECTIVE This study aimed to characterize alteration in the immunohistochemical expression of pRb in normal tissue of the salivary gland surrounding pleomorphic adenoma, the tumor cells of pleomorphic adenomas, and carcinoma arising in pleomorphic adenoma. STUDY DESIGN A selected series of 29 cases of pleomorphic adenomas, and 27 cases of carcinoma ex-pleomorphic adenoma (undifferentiated an...
متن کاملSquamous cell carcinoma ex pleomorphic adenoma a case report
A rare case of squamous cell carcinoma ex pleomorphic adenoma in maxillary sinus is presented. The patient is a 50-year-old woman presenting with a slow-progressive swelling in left side of her face that she has noticed 2 years earlier. The lesion was not painful and caused asymmetry and mild exophthalmos. Microscopic examination revealed that the tumor was composed of two components partly of ...
متن کاملComparison of the Blood and Lymphatic Microvessel Density of Pleomorphic Adenoma and Basal Cell Adenoma
BACKGROUND Pleomorphic adenoma (PA) is the most common tumor of the salivary gland, while basal cell adenoma (BCA) is an uncommon neoplasm. Blood and lymphatic vessels are crucial for tumor metabolism. The aim of this study was to compare the blood and lymphatic vascular density and vascular and endothelial growth factor (VEGF) expression in PA and BCA tumors. In addition, cell proliferation wa...
