Abstract

Infiltrating syringomatous adenoma of the nipple (SAN) is a very rare benign tumour of the breast. It’s often present with a lump in areolar/ nipple complex (ANC), and can occur in women of all ages. The clinical and radiology finding are suggestive of breast cancer. It is known to cause local infiltration, but according to the literature reviews, there has been no reported case of metastasis. Surgical excision of the lump is the curative management. We present a case report of 43 years old female, who presented with history of left breast pain and mass. She had triple assessment, and showed to have infiltrating syringomatous adenoma of the nipple. She underwent lump excision. Infiltrating syringomatous adenoma of the nipple should be ruled out from the deferential diagnosis of areolar and nipple lumps to avoid misdiagnosis and unnecessary management.
