Minimally Invasive Carcinoma ex Pleomorphic Adenoma Arising from Parotid Gland

Pleomorphic adenoma is a common benign tumor. But malignant transformation in pleomorphic adenoma is rare. Carcinoma ex pleomorphic adenoma is sub classified into noninvasive, minimally invasive and invasive carcinoma ex pleomorphic adenoma. Only 33 cases of minimally invasive carcinoma ex pleomorphic adenoma have been reported in the English literature. We report a case of 35 old female with a left parotid mass. The histopathological diagnosis was minimally invasive carcinoma ex pleomorphic adenoma. The minimally invasive carcinoma ex pleomorphic adenoma has not been reported from Korea. Herein, we present the case with review of the related literatures. (J Clinical Otolaryngol 2017;28:100-103)
