A Rare Case of Carcinoma Ex-pleomorphic Adenoma. [PDF]

J Microsc Ultrastruct, 2023
Abstract Pleomorphic adenoma is the most common benign salivary tumor involving the parotid gland. However, malignant transformation to carcinoma expleomorphic adenoma (CXPA) is an exceedingly rare occurrence. Malignant patterns reported with pleomorphic adenoma include CXPA, metastasizing pleomorphic adenoma, and carcinosarcoma. Firm mass in
