Abstract
A 62-year-old male had primary multiple cancers of the palatine tonsil and parotid gland. He visited our clinic because of a sore throat. On examination, a tumor associated with an ulcer was observed in the right palatine tonsil. There was no swelling of the regional lymphnodes. Histologically, the tumor was diagnosed as squamous cell carcinoma. He was treated by irradiation with a total of 6000 rads to the right tonsillar area. The response was excellent and the tumor disappeared.
However, four months after the treatment, a swelling of the left parotid gland region was observed, and a malignant parotid tumor was suspected. Histological examination revealed malignant mixed tumor. After surgery the tumor recurred locally and metastase to the lung were suspected. The patient died about three months later.
