Clinics in diagnostic imaging (147). Male breast carcinoma

A 51-year-old man with no significant medical history was referred to our institution for further management of a palpable, painless right breast lump that had been gradually increasing in size for a period of six months. Physical examination revealed a firm right breast lump and bloody right nipple discharge, but no skin involvement or axillary lymphadenopathy was observed. Subsequent mammography and breast ultrasonography demonstrated a discrete, heterogeneous and vascular right breast mass with spiculated and angulated margins. The breast mass was found to be an invasive ductal carcinoma on ultrasonography-guided core needle biopsy. This case illustrates that a combination of detailed clinical history, careful physical examination and radiological assessment using mammography and breast ultrasonography may be used to identify cases suspicious for male breast carcinoma that warrant biopsy.
