An unusual presentation of Paget's disease of the nipple in a young woman: a case report.

A 27-year-old female patient presented with a slight scaly, crusting, erythematous patch close to the right nipple 10 years ago. When her symptoms failed to respond to topical therapy 3 months later, nipple biopsy was performed and revealed Paget's disease of the breast. The patient underwent unilateral mastectomies with sentinel lymph node biopsy. She has stayed healthy and has had no evidence of breast cancer recurrence since surgery.
