Abstract
Pleomorphic adenoma is the most prevalent benign tumor of the parotid gland, and shows potential malignancy. Carcinoma ex pleomorphic adenoma (CXPA) can occur in 3%-15% of pleomorphic adenoma cases. Owing to its clinical similarity to benign tumors, critical information related to CXPA can be easily overlooked, leading to frequent misdiagnosis of the condition. In this article, we report a rare case of CXPA found in the 55-year-old male patient with characteristic clinical, radiographic, and histological features, and subsequent treatment.
