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.
黏液瘤是一种良性结缔组织肿瘤，最常见于心脏。由于外耳道黏液瘤极为罕见，其诊断可能很容易被延误，或者可能被误诊为其他疾病。此外，因为它可能是卡尼综合征（常染色体显性综合征）的一部分，所以其正确诊断非常重要。我们接诊了一名10岁女孩，她左耳耳道入口处的耳屏后表面有一个肿块。细针穿刺显示囊性肿块内有黏液样物质，但其细胞学检查未能确诊。整个肿块被手术切除，诊断为黏液瘤，在细胞稀少的基质中有星状梭形细胞增殖。全面检查未能发现任何卡尼综合征的表现，她的最终诊断为外耳道孤立性黏液瘤。这是韩国文献中首次报道的关于外耳道黏液瘤的研究。
