Pure low-grade DCIS in a male patient: a case report.

Breast cancer in males represents a small proportion of all cancers diagnosed. Pure ductal carcinoma in situ (DCIS), a low-grade form of breast cancer, is even more rare in male patients. We present a case of a 47-year-old male patient with a tender breast lump that was noted for 6 months. He was subsequently found to have a low grade, pure micropapillary and cribriform type DCIS with no evidence of invasive disease. Current literature does not provide distinct guidelines regarding management of male breast cancer, and it is currently managed in a similar fashion to female breast cancer.
