Summary:We describe a 14-year-old boy with a mucoepidermoid carcinoma arising in the hard palate. He visited our clinic because of a swelling in the left side of the hard palate on May 16, 1995. A hard palate tumor was diagnosed because of a 25×30mm diffuse, painless swelling in the left side of the hard palate. A biopsy was performed, and the histopathological diagnosis was a mucoepidermoid carcinoma (well differentiated type). With the patient under general anesthesia, a partial maxillectomy was performed. There has been no evidence of recurrence or metastasis after the operation. In this patient, we performed immunohistochemical studies using MIB-1 antibody, which detects Ki-67 antigen. The MIB-1 positive index was 2% to 3%. The results indicated that the lesion was a low-grade malignancy.
