Solitary Fibrous Tumor of the Tongue: a Case Report.

Introduction: Solitary fibrous tumor (SFT) is a fibroblastic neoplasm of uncertain biological origin that is rare in the tongue.

Case Report: A 42-year-old woman presented with a painless, submucosal nodule in the tongue. Based on the clinical hypothesis of benign mesenchymal neoplasia, the lesion was excised, and the specimen was submitted for histopathological analysis.

Epithelial membrane antigen and DOG1 expression in minor salivary gland tumours.

Epithelial membrane antigen (EMA) and DOG1 are used as marker of epithelial cells, particularly the luminal cells, of salivary gland tumours. The aim of this study was to compare the EMA and DOG1 expression in tumours of minor salivary glands. Cases of pleomorphic adenoma (PA), basal cell adenoma (BCA), canalicular adenoma (CA), adenoid cystic carcinoma (ACC), polymorphous adenocarcinoma (PAC), mucoepidermoid carcinoma (MEC) and epithelial-myoepithelial carcinoma (EMC) were submitted to immunohistochemistry for EMA and DOG1.

Approach and Treatment of Giant Luminal Unicystic Ameloblastoma.

Unicystic ameloblastoma is an odontogenic tumor that affects mainly young patients and usually involves the posterior region of the mandible. In this article, we report on the case a 12-year-old girl presenting with an 8-month history of facial swelling in her lower right quadrant. Radiographic examination revealed a unilocular radiolucent lesion extending from the body of the mandible through to the angle and ascending ramus.
