Myoepithelial Carcinoma Arising In Pleomorphic Adenoma of Palatal Minor Salivary Gland: Report of a Rare Case

Shoor Hitesh, Pai Keerthilatha M, Vineetha R

Salivary gland neoplasms composed exclusively or predominantly of myoepithelial cells are relatively uncommon and constitute 1 % of all salivary gland tumours. Most of them behave in a benign fashion and are designated as myoepithelioma. The malignant counterpart is known as myoepithellial carcinoma or malignant myoepithelioma, which is quite rare. This report presents about a rare case of a 45 year old female who had a painless swelling in the left posterior palatal region since childhood with a sudden increase in size since 2 months. Pre-operative biopsy failed to reveal any malignant changes. The mass was surgically excised and thorough evaluation revealed a myoepithelial carcinoma arising in pleomorphic adenoma of palatal minor salivary gland.
