[A Case of Breast Cancer in the Elderly Localized in the Nipple]

An 89-year-old woman presented to our clinic with a complaint of a wound in the left nipple. The pathological diagnosis via skin biopsy revealed adenocarcinoma. A physical examination, mammography, ultrasonography, and CT scan revealed a mass in the left nipple. However, a definite diagnosis could not be established by skin biopsy. Left breast-conserving surgery and sentinel lymph node biopsy were performed for diagnosis and treatment. Histological examination revealed a scirrhous type invasive ductal carcinoma in the left nipple and areola with skin invasion and lymph node metastasis. Radiation and hormone therapy were used as adjuvant therapy. She is alive with no local recurrence for 5 months post surgery. Since ductal carcinoma of the nipple is uncommon, we present this case report along with a review of the relevant literature.
