We report two cases of male breast cancer with reference to the literature.Patient 1 was a 79-year-old man who noticed a right subareolar tumor. The tumor was diagnosed asinvasive ductal carcinoma by core needle biopsy,which was positive for estrogen and progesterone receptor.He was treated orally with anastrozole 1 mg/day every day because he refused surgery.The tumor disappeared9 months later,so he discontinued the anastrozole.However,the tumor had progressed 9 months later,andhe received endocrine therapy again.Patient 2 was a 65-year-old man who complained of right nipple erosion for the preceding 2 years.He wasdiagnosed with Paget’s diseased by a dermatologist. He underwent resection of the erosion and has beenfollowed without endocrine therapy.Male breast cancer is an uncommon disease and accounts for less than 1% of all breast cancers. Theprognosis of male breast cancer was considered comparatively poor before,but it can be cured in early casesas in females. Patients who have tumors that are estrogen-and progesterone-positive may benefit fromendocrine therapy
