Radiography of gynecomastia and other disorders of the male breast.
Mammographic features of 22 pathologically proved cases reflecting disorders of the male breast are described. Two patterns of gynecomastia were observed: a dendritic pattern seen in association with breast enlargement for 6 months or more, and a more florid triangular pattern, seen in association with breast enlargement of recent onset. Male breast carcinoma may be distinguished from gynecomastia by its eccentric location, spiculation, and, in some cases, calcification or involvement of the skin and nipple. Benign conditions simulating carcinoma included a case of drug-induced gynecomastia and a case of inflamed inclusion cyst.
