Abstract

A nodular hidradenoma, clear cell hidradenoma or eccrine acrospiroma is an exceedingly rare entity in the breast tissue. It is a benign adnexal cell tumor derived from eccrine sweat gland.

To our knowledge approximately thirty cases are reported in English literature. The aim of this article is to raise the awareness of this tumor so that patients can receive appropriate diagnosis and therapy. Herein we report a case of 51-year-old female who underwent complete wide excision of left lateral breast mass. Two years ago the left lateral breast biopsy was diagnosed as an atypical papillary lesion. Essentially, this diagnosis was inconclusive and the breast mass resection followed and the final diagnosis was nodular hidradenoma.
