Ductal carcinoma in situ (DCIS) of the male breast treated by lumpectomy and breast irradiation.

A male patient with ductal carcinoma in situ (DCIS) of the breast, treated with lumpectomy and postoperative breast irradiation, is presented. Because of associated obesity, the patient felt that mastectomy would leave him with a noticeable cosmetically unacceptable deformity. Radiotherapy was administered using the exact techniques used to treat the female breast. At 44 months following completion of radiotherapy, the patient is free of disease and has an excellent cosmetic result. Thus, if there are compelling reasons to avoid mastectomy in a male patient, lumpectomy and breast irradiation should be considered as a reasonable alternative for treatment of DCIS.
