Mucoepidermoid tumor is found in a high incidence in adults, however, in a relatively low incidence in children. We reported a case of mucoepiderrnoid tumor originated from the minor salivary gland in a 13-year-old girl.<BR>The patient visited us with complaining of the swelling in the palate. Under general anesthesia the tumor was resected and the clinical course is good.<BR>Histological findings revealed that this case was Grade II according to the Komori's classification.<BR>We also referred to 34 cases of mucoepidermoid tumor in the First Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tokyo Medical and Dental University during past the 14 years from 1976 to 1989. The incidence of the mucoepidermoid tumor in children was only 5.9% (2/34) and clinical courses of them are good. The five year survival rate of all the 34 cases was 82.5%.<BR>Eventhough the prognosis of the mucoepidermoid tumor is statistically good, the present case seems necessary to follow-up for a long time, considering the moderate differentiation of the tumor.
