Oncocytic mucoepidermoid carcinoma of parotid gland origin.

This article reports 3 cases of oncocytic mucoepidermoid carcinoma of the parotid gland and compares them with 9 cases from the literature with emphasis on clinical behavior, treatment, and recurrence rate. The tumor occurs most often in the middle-aged to elderly, with a decided predilection for the parotid gland. All three oncocytic mucoepidermoid carcinomas from the Armed Forces Institute of Pathology series were low grade with extensive oncocytic change.

A rare case of a sebaceous nevus in the external auditory canal.

We report the case of a patient who came to us for evaluation of a progressive unilateral hearing loss and who was found to have a sebaceous nevus in an unusual location: the external auditory canal. A sebaceous nevus is a congenital organoid mass that occurs primarily on the face, scalp, and periauricular regions. Despite the predilection of sebaceous nevi for the head and neck, reports of this lesion rarely appear in the otolaryngology literature.
