Syringomatous adenoma of the nipple: a case report

Abstract

Syringomatous adenoma of the nipple is a rare disease. To our knowledge, only 23 cases have been reported in the literature. We present the case of a 36-year-old lactating woman with syringomatous adenoma of the nipple, in whom local excision of the tumor was performed. Histologically, the tumor consisted of tubules, ductules and epithelial cell strands, and most of the proliferating ducts showed a characteristic teardrop or comma-shaped appearance. Careful monitoring to detect local recurrence is considered necessary, because syringomatous adenoma of the nipple, while being benign, is a locally invasive tumor.
