Abstract
Malignant myoepitheliomas(myoepithelial carcinomas) are uncommon, and we kn ow of only 29 reported cases. We present a new case together with its clinical, histological, and immunoh istochemical features. The tumour was located in the inferior vestibular su lcus of a 64-year-old woman. She was treated by wide local resection. Malig nant myoepitheliomas are distinguished from benign myoepithelial neoplasms by their infiltrating and destructive growth. The tumour cells may be spind le-shaped or more rounded (plasmacytoid cells) and contain cellular pleomor phism and mitotic activity. The clinical and biological behaviour of this tumour is not get known and t here is little information about treatment and prognosis.
