Mucoepidermoid Carcinoma of the Maxillary Sinus ― Case Report―
Mucoepidermoid carcinoma is an adenocarcinoma derived from the mucous ducts. Three kinds of cells, mucous cells, intermediate cells and epidermoid cells, constitute mucoepidermoid carcinoma, and this tumor is of three grades; low-grade, intermediate-grade and high-grade. The prognosis of high-grade tumors is very poor. Most cancers in the paranasal sinuses are squamous cell carcinomas. Mucoepidermoid carcinoma of the maxillary sinus is very rare. We encountered a case of mucoepidermoid carcinoma of the maxillary sinus in a 73-year-old female. The details of the case and a review of the literature are presented.
