Fine Needle Aspiration Cytology of Breast Fibroadenoma

Abstract

FA of the breast remains a diagnostic challenge for the cytopathologist. A considerable amount of benign breast lesions can mimic FA on cytology, and such diagnostic categories as "fibroadenomatous lesion" or "consistent with FA" are associated with low diagnostic accuracy. While the cytologic requisites for entering a program of conservative management of FA are established, it seems that strict diagnostic criteria should be applied even at the expense of diminishing sensitivity.
