Mammography Findings of Male Breast Diseases

Over the past 2 decades, the percentage of men presenting with breast complaints has increased from 0.8% to 2.4%, and men now account for 1% of all breast cancer cases. The most common male breast mass is gynecomastia, followed by lipoma and epidermal inclusion cysts. Because there is a paucity of parenchyma as compared with the female breast, the malignancy rapidly progresses to the next stage, with the appearance of secondary signs like nipple retraction, fixation to deeper tissues, skin ulceration or adenopathy. Diagnostic evaluation is needed only when the palpable mass is unilateral, hard, fixed, peripheral to the nipple, or associated with nipple discharge, skin changes, or lymphadenopathy. Male breast cancer usually occurs in a subareolar location or is positioned eccentric to the nipple; occasionally, it occurs in a peripheral position. Secondary signs like skin thickening, nipple retraction, and axillary lymphadenopathy may be seen. Microcalcifications can occur. Mammography can accurately distinguish between malignant and benign male breast disease. Radiologists are generally less familiar with breast disease in males compared with females. In this article, we discuss the clinical, and mammographic features of a variety of benign and malignant diseases that can occur in the male breast.
