CASE N°07 – Syringoadenoma of the Breast
Well defined fibrous nodule about 0,8 cm. in diameter. The nodule was located on superficial breast tissue, around the nipple. It was clinically suspicious for neoplasm.
Cytological material: Breast FNA
Low cellularity. Papillary aggregates of epithelial duct cells sometimes with cytoplasmic vacuolization and nuclear irregularity, occasionally with phenomena of cellular cannibalism. Foamy cells and red blood cells are also present.
Atypical finding, probably benign
Hystological material: Nodule excision
This particular and rare benign tumor of the breast may present clinical (& cytological) aspect that mimics breast ductal carcinoma. The site of the lesion (superficial & around the nipple), lack of cellular dischoesion & obviously atypical nuclear features may help to identify this uncommon tumor type.
