RESUMO
The carcinoma of the male breast is a rare lesion, being aproximatelly 100 times less frequent than in women. Of 1930 cases of mammary cancer seen at the Hospital of Oncology of the National Medical Center, I.M.S.S. during a period of 10 years we found 10 histologically proved cases of carcinoma of the male breast. Their microscopic appearence was that of an invasive ductal carcinoma. The surgical treatment consisted in radical mastectomy on six patients, supermastectomy is one case and simple mastectomy in other. Two patients received radio and chemotherapy. In three patients bilateral orchiectomy was done and in other two cases a bilateral adrenalectomy was performed. The results of the review of these cases are compared with other previously reported.
