A 29-year-old man presented for evaluation of a left subareolar mass. It had been present for 8 years but had recently begun to rapidly enlarge. He denied nipple discharge or chest-wall changes. Family history was notable only for a grandmother with breast cancer. There was no personal history suggesting neurofibromatosis. He had no history of testicular masses, chest trauma, headaches, vision changes, or neoplasms. He had occasionally used dietary supplements while wrestling competitively in high school but otherwise took no medications, occasionally used alcohol, and did not smoke or use recreational drugs. A large, firm, and palpable left subareolar mass without skin changes was identified on exam (Fig. 1). There was right-sided gynecomastia, but no café au lait spots or freckling of the axillae.
