ABSTRACT

A blue nevus, characterized by the proliferation of dermal dendritic melanocytes, usually appears as a solitary, small, asymptomatic blue-to-blue-black macule or papule on the dorsal aspect of the extremities, scalp, or buttocks. Blue nevi have also been reported in several extracutaneous sites, including the vagina; prostate; and intraoral, sinonasal, and colorectal mucosae. A 38-year-old female presenting with intermittent dizziness had a blue-black mass in the left middle ear, behind an intact tympanic membrane; the mass was evident on otoendoscopic examination. The mass was surgically removed and identified histologically as a benign blue nevus. To date, two cases of blue nevi in the middle ear have been reported. Here, we describe another such rare case.
