Abstract

Myxoma is a benign connective tissue tumor that is most commonly found in the heart. Because myxoma of the external ear is extremely rare, its diagnosis may be easily delayed or it may be misdiagnosed as another disease. Moreover, because it can be a part of Carney complex (autosomal dominant syndrome), its correct diagnosis is very important. We experienced a 10-year-old girl who had a mass on the posterior surface of the tragus at the entrance of the left ear canal. Fine-needle aspiration revealed mucoid content of the cystic mass, but its cytology did not confirm the diagnosis. The whole mass was surgically removed, and the diagnosis was confirmed as myxoma with a stellate spindle cell proliferation in the hypocellular matrix. Thorough examination failed to determine any presentation of Carney complex, and her final diagnosis was isolated myxoma of the external auditory canal. This is the first reported study regarding myxoma of the external auditory canal in the Korean literature.
