Clinicopathological analysis of the mucoepidermoid carcinoma of minor salivary gland

Abstract

Six cases of mucoepidermoid carcinoma of minor salivary gland were reported, and all the cases were primary. Three case of carcinomas originated in the hard palate, two originated in the buccal mucosa, and one originated in the lower gingiva. As a result of histological classification by W.H.O. (1991), three were well-differentiated type and three were poorly-differentiated type. Metastasis of cervical lymph node was observed in one of the cases of poorly-differentiated type. In five cases, surgery alone was carried out. In one case, the combination of surgery, chemotherapy, and radiotherapy was carried out. To date, no recurrence and metastasis has been noted, and all the cases have had good prognosis.
