A Case of Breast Cancer Located in the Nipple Detected by Screening Mammography

Abstract

We report a rare case of breast carcinoma observed in the nipple. A 43-year-old female presented with calcifications in the right nipple detected by screening mammography. An elastically hard mass was found in the right nipple, with no erosion or redness, and the mammogram showed a cluster of pleomorphic calcifications. The right nipple presented with fine high-echo spots on an ultrasonogram and a pale contrast area on a magnetic resonance imaging (MRI) scan. Ductal carcinoma in situ (DCIS) was diagnosed based on a biopsy, and a partial resection and sentinel lymph node biopsy of the right breast was performed. A histopathological examination revealed DCIS at the nipple. Post-operative radiation therapy to the intact breast was performed, and a future nipple-areolar plastic surgery is planned.
