Case report: infiltrating syringomatous adenoma of the breast--appearances on mammography and ultrasonography.

Infiltrating syringomatous adenoma is a recently-recognized locally-invasive breast neoplasm which clinically may mimic carcinoma. We describe bilateral syringomatous adenomata in a screened patient, indistinguishable from carcinoma on mammography and ultrasound examination. The clinical and pathological features which suggest the diagnosis are discussed.
