Abstract
We report a case of an adenoma of the nipple in a 33-year-old Japanese woman who presented with a 2-year history of itching, eczema, and discharge from the left nipple. Examination revealed a firm, well defined and erosive tumor measuring 10×11 mm that was sore, crusted, and indurated. There was a slight serosanguineous discharge from the tumor. Cytological material from the tumor obtained from the discharge and by fine needle aspiration (FNA) and scraping showed a papillary cell cluster thought to be a benign papilloma.
We performed a tumor resection with preservation of the nipple. The histological diagnosis was adenoma of the nipple. The patient was left with a cosmetically well-preserved nipple. No recurrent tumor has been observed for two years after surgery.
