Abstract

Myxoma is a benign mesenchymal neoplasm found in the heart, bone, and other soft tissues. However, myxoma of the external auditory canal is extremely rare. Since myxoma of the external auditory canal can be manifested as a part of the Carney complex, an autosomal dominant multiple familial neoplastic disorder, correct diagnosis and thorough investigation is important. We report a case of a 59-year-old man who presented to hospital with a complaint of growing mass within the right external auditory canal during one month. The surgical excision was done, and the histopathological examination revealed myxoma. In this article, we report the magnetic resonance imaging and computed tomography findings of the myxoma of the external auditory canal and correlate with the histopathological finding.

점액종은 양성 중간엽종양으로서 심장, 뼈를 비롯한 연부조직에서 생길 수 있지만 외이도에서 발생하는 경우는 극히 드물다. 한편, 외이도의 점액종은 상염색체 우성으로 유전되는 다수의 가족성 종양 증후군인 Carney 복합체(complex)의 한 부분으로 발현될 수 있기 때문에 진단 및 철저한 조사가 중요하다. 본 증례에서 59세 남성 환자가 한 달 전부터 발생해서 점점 커지는 양상의 오른쪽 외이도 종괴를 주소로 내원하였고, 수술적 절제 후 조직병리검사 결과 점액종으로 확진되었다. 본 증례는 외이도 점액종의 자기공명영상 및 전산화단층촬영 소견을 보고하고, 조직병리 소견과 관련해서 이해해 보고자 한다.
