Syringomatous adenoma of the nipple with microcalcifications on mammography: A case report.

ABSTRACT

Syringomatous adenoma of the nipple (SAN) is a rare benign lesion which often presents as a subareolar mass with associated nipple shape changes including pruritus, crusting, and discharge It is thought that syringomatous tumors arise from eccrine glands of the nipple and areola. Due to its locally infiltrative growth pattern the main differential is with low-grade adenosquamous carcinoma which requires more aggressive surgical treatment. Syringomatous adenoma of the nipple can recur, and therefore complete local excision is recommended. We present a case of a syringomatous adenoma of the nipple diagnosed after nearly 5 years of observation with microcalcifications noted on mammography.
