title: True malignant mixed tumor (carcinosarcoma) of palatal minor salivary gland origin.
abstract: True malignant mixed tumor (carcinosarcoma) of salivary gland origin is exceedingly rare and is distinguishable from the more frequently occurring carcinoma ex pleomorphic adenoma. This paper reports a case of true malignant mixed tumor originating from a palatal minor salivary gland of a 55-year-old male. Histologically, nests of poorly differentiated adenocarcinoma were scattered in a sarcomatous background which partially showed an unequivocal chondrosarcoma. Clinical course of the present patient suggested that a pre-existing benign minor salivary gland lesion developed to a carcinosarcoma.
