Lipomatous Pleomorphic Adenoma in the Palatine Gland

Abstract

Lipomatous pleomorphic adenoma is an unusual subtype of adenoma with a lipomatous stromal component. Although there are a few reports about lipomatous pleomorphic adenoma in the parotid gland, we report an extremely rare case of lipomatous pleomorphic adenoma in the palatine gland of a 33-year-old female. Histologically, approximately 80% of the tumor tissue was fatty tissue containing univacuolar adipocytes. The pleomorphic epithelial elements consisted of duct-like cells forming small lumina and also consisted of spindle-shaped myoepithelial cells.
