Material From 1960 to 1990, 581 cases of male breast cancer (MBC) were reviewed in 19 Cancer Institutes in France. 23 (4%) were pure DCIS. The median age was 56.5 years (ext. 26–77). Five patients had less than 40 years (22%). Gynecomastia was found in 10 out of 23 patients (43%). Three had family history of B. C. According to TNM classification, we found 6 impalpable lesions (T0) discovered by serosanguineous nipple discharge, 7 T1, 6 T2, and 4 Tx. Treatment The surgery consisted of 3 lumpectomies, 16 modified, 2 subcutaneous and 2 radical mastectomies. 16 patients had axillary dissections and 6 irradiation on the chest wall. Histology All cases were pure DCIS: in 14 the subtype was clearly identified: papillary (4), papillary intracystic (3), mixed papillary and cribriform (3), comedocarcinoma (2), cribriform (1), apocrine (1). Three patients had local recurrences: two occurred in the patients initially treated by lumpectomy alone: the first was again a DCIS, but the second was an infiltrating carcinoma; this patient died by metastases. The last relapse occurred on the chest wall in a patient treated by mastectomy. One patient developed a contralateral DCIS. Two patients developed a lung and kidney cancer respectively. In the literature the rate of DCIS in man varies from 0 to 16%. The serosanguineous nipple discharge seems a frequent symptom, especially in young men. The main histologic subtype is papillary (pure or intracystic). Mastectomy is the treatment of choice.
