A previously healthy 40-year-old man presented with a 3-month history of a right breast mass slowly enlarging with associated pain. The patient denied history of local trauma, and his family history was negative regarding breast or ovarian cancers. The patient had no history of liver disease, hormonal therapy, or radiation to the chest wall.

The physical examination disclosed an obese man with no signs of hypogonadism or liver failure. There was a 3 × 4-cm hard, irregular, mobile nodule in the retroareolar area of the right breast, tethered to the overlying skin but not fixed to the underlying muscle. There were no other masses on the chest wall. The ipsilateral lymph nodes were palpable. The left breast and axilla were normal. Right mediolateral oblique mammography (Figure, A) and computed tomography scan of the chest (Figure, B) are shown.
