Mucoepidermoid Carcinoma Superimposed on a Warthin's Tumor: A Case Report and Review of the Literature
Introduction: Warthin's tumor (WT) is the second most common neoplasm of the parotid gland and consists of two components, including lymphoid stroma and glandular epithelium. The malignant transformation of this tumor occurs most often in the lymphoid component; however, the carcinomatous trans...
