Abstract
We have had two patients with breast cancer in the nipples.
The first patient was a 63-year-old woman. She complained of bloody discharge and a mass in her right nipple for the past 6 months. Her right nipple was swollen to 2 cm, and biopsy results suggested that she had non-invasive ductal carcinoma. A right partial breast resection and sentinel lymph node biopsy were performed. The sentinel lymph node biopsy was negative, but the stump of the C area mammary gland was positive and thus required additional resections. The resected specimen was mainly non-invasive ductal carcinoma, but there was some invasive ductal carcinoma present.
The second patient was a 90-year-old woman. She had been aware of her left nipple mass for three years, but she did not do anything until she visited us with bleeding from her nipple. Her left nipple was swollen to 3 cm, and there was also a 5-cm mass in the AC region of her right breast. Biopsy results revealed that both were invasive ductal carcinoma, and we performed a left mastectomy, axillary dissection, and right mastectomy. The left nipple mass was solid tubular carcinoma. There was proliferation and invasion of atypical ductal epithelial cells in the mammary gland under the nipple. The right breast mass was papillotubular carcinoma.
