Fine needle aspiration cytology and core biopsy histology in infiltrating syringomatous adenoma of the breast. A case report.
BACKGROUND
Infiltrating syringomatous adenoma is a rare tumor of the breast that can radiologically mimic invasive duct carcinoma. Detailed fine needle aspiration cytology and needle core biopsy findings on this lesion have not been previously described.


METHODS
The clinical, radiologic and pathologic findings of an infiltrating syringomatous adenoma of the breast in a 71-year-old female who presented with a subareolar lump are described. The cytology of the tumor was characterized by a combination of a background of plump, fibroblastoid cells and cohesive sheets of bland epithelial cells. Histologically the tumor showed infiltrating, duct-like structures with squamous metaplasia and a desmoplastic stroma.


CONCLUSIONS
Fine needle aspiration cytology and needle core biopsy can distinguish infiltrating syringomatous adenoma from malignant disease of the breast.
