RADIOLOGICAL FEATURES OF PAPILLARY CARCINOMA OF THE BREAST

Seventeen patients with papillary carcinoma of the breast were analyse d with respect to the radiological findings by three experienced breas t radiologists. The most frequent mammographic appearance of papillary tumours was of an ill-defined (70%) and lobulated (60%) mass and at u ltrasound as a well-defined (76%), inhomogeneous (62%) and hypoechoic (92%) lesion, Histopathological subtypes of encysted papillary carcino ma, encysted papillary carcinoma with an invasive focus and invasive p apillary carcinomas could not be predicted from the radiological featu res, although invasive tumours tended to be larger at presentation tha n the other subtypes.
