Abstract
An interesting case of malignant parotid tumor with a very long (about 30 years) duration is presented. At the same time this patient had gastric adenocarcinoma, detected only by chance.
In 1986, a 76-year-old man visited our clinic, complaining of spontaneous pain in the right posterior part of the buccal region. Physical examination revealed a gigantic tumor in both the right buccal and the right parotid region and symptoms of facial nerve palsy. After he had undergone subtotal gastrectomy for gastric cancer which had been found out with sudden hematemesis as a clue during the waiting period prior to the admission to our clinic, excision of the parotid tumor was performed. However he died of cachexy about three months after the operation. Histopathologic diagnosis of the surgical specimen was established as poorly differentiated mucoepidermoid tumor (with high malignancy) of the parotid gland, but differential diagnosis with carcinoma in pleomorphic adenoma was difficult.
