Abstract

|
|
Carcinoma ex pleomorphic adenoma is a rare malignant salivary gland tumor. The carcinomatous component of the carcinoma ex pleomorphic adenoma is mostly one type such as adenocarcinoma NOS, salivary duct carcinoma and undifferentiated carcinoma. We present a case of carcinoma ex pleomorphic adenoma including two carcinomatous components. The tumor occurred in the palate of a 70-year-old man. Histopathologically, the tumor was composed of both benign pleomorphic adenoma and the carcinoma area that showed adenocarcinoma NOS and squamous cell carcinoma. Finally this case was diagnosed as carcinoma ex pleomorphic adenoma including two carcinomatous components.
