외이도에 발생한 관상선종 1예

Abstract

Tumors occurring in the external auditory canal (EAC) are rare. In particular, tubular adenoma (TA) is an extremely rare sweat gland neoplasm occurring in the EAC and is generally considered as benign. Up to now, less than one hundred cases of TA have been reported in the English literature. In fact, a comprehensive review of literature shows that TA in the EAC has seldom been reported. Herein, we report a case of a 35-year-old man with TA that occured in the EAC, together with characteristic histopathological findings.
