Infiltrative Oncocytoma arising from minor salivary glands of palate: A Case Report

Abstract

Oncocytoma of salivary gland origin is an uncommon tumor found mainly in the parotid gland. On rare occasions, oncocytoma arise in the intra-oral minor salivary glands; having a greater tendency for locally aggressive behavior and infiltrating the adjacent tissues due to incomplete encapsulation. The current case is of particular interest due to the infiltrating nature of the lesion in a 70-year-old male patient, who denied any symptoms, even with the lesion being extensive. The histopathological features in the current case were suggestive of benign oncocytoma. The tumor was surgically excised under general anesthesia and the postoperative course was uneventful and the patient is on regular follow-up.
