title: Nodular hidradenoma of male breast: Cytohistological correlation.
abstract: Nodular hidradenoma is an established entity as a skin adnexal tumor arising from eccrine sweat glands. A skin adnexal tumor located in the breast is unusual and is one of the differential diagnoses for subareolar breast nodules. With the exception of gynecomastia, other lesions of the male breast are not very common. The review of literature showed only 25 reported cases till date. The rarity of this neoplasm and failure to identify its morphologic features may lead to misdiagnosis. Being itself rare, cytological features of this lesion are hardly encountered in case reports. We report a case of an 18-year-old male who presented with a left breast lump and underwent fine needle aspiration and was diagnosed as having a benign skin adnexal tumor. Later it was confirmed by histopathology to be a nodular hidradenoma.
