Q. All of the following gland tumors are correctly matched with the appropriate characteristic EXCEPT a- Pleomorphic adenoma - most common salivary gland tumor b- oncocytoma - eosinophilic-staining cells c- adenolymphoma - Warthin’s tumor d- mucoepidermoid tumor - “mixed tumor” e- Adenoid cysts carcinoma - presents with pain Answer: D. “Mixed tumor” properly refers to pleomorphic adenoma, which often demonstrates myxoid and cartilage-like elements in addition to stellate or fusifrom epithelial cells. Oncocytoma is characterized by cells with granular eosinophilic cytoplasm. Adenolymphoma (papillary cystadenoma lymphomatosum) is often called Warthin’s tumor. Adenoid cystic carcinoma often presents with pain due to infiltration of perineural spaces.
