Highlights ■ Immunohistochemistry distinguishes Warthin-like  mucoepidermoid carcinoma from metaplastic Warthin tumor. ■ CK7, mitochondrial patterns, and double-layer epithelium  suggest metaplastic Warthin tumor. ■ Basal CK14, CK5/6, and p63 distinguish metaplastic  Warthin tumor from Warthin-like mucoepidermoid  carcinoma. ABSTRACT Objective: This study aimed to analyze the clinicopathological and immunohistochemical profiles of unconventional Warthin tumors and mucoepidermoid carcinomas. Methods: Eleven low-grade salivary gland tumors with Warthin-like features were analyzed. Group A (n=6) showed a double-layered oncocytic epithelium in less than 50% of the […]

ABSTRACT Mammary analogue secretory carcinoma is a rare neoplasm usually confused with other neoplasms in the salivary glands region. It has great similarity with the breast carcinoma. We report a case of a patient who presented with gingival submucosal bleeding and lesion, with the initial histopathological examination revealing salivary gland neoplasm of low crane. Computed tomography revealed the lesion near the tooth 27, with extension to the floor of the left maxillary sinus and to the palate mucosa. Resection of […]
