A 49-year-old male with a mucoepidermoid tumor of the parotid gland was treated surgically after combined therapy using radiation and a daily low dose of cisplatin with excellent results. The histological diagnosis based on an open biopsy was a solid type mucoepidermoid tumor with epidermoid cells dominant. The tumor was classified as a high grade malignancy.<BR>The tumor was remarkably decreased in size with radiation therapy. The total dose of cisplatin was 240 mg and the total dose of radiation was 60 Gy. Xerostomia and dermatitis were observed as side effects, but the patient recovered following symptomatic therapy. Neither recurrence nor metastasis has been found in the 2 year follow-up period since radical surgery.<BR>These results suggest that radiation therapy might be useful for the treatment of mucoepidermoid tumors.
