Bilateral DCIS following gynecomastia surgery. Role of nipple sparing mastectomy. A case report and review of literature

Bilateral ductal carcinoma in situ of breast is a very rare disease in men. Ductal carcinoma in situ (DCIS) is an abnormal proliferation that involves the ductal epithelium and it has the potential of evolving into an invasive tumour. Gynaecomastia (female like breast in men) is a benign condition though it is associated with a reported 3% incidence of unilateral invasive breast cancer.(2) Synchronous bilateral breast cancer in association with gynaecomastia is exceptionally rare. The recommended treatment for DCIS in male is mastectomy. So far only 2 cases of bilateral DCIS in male patients has been reported in the literature treated with skin and nipple sparing mastectomies. We report another case of synchronous bilateral DCIS in a male treated with skin and nipple sparing mastectomies. A 44 year-old man with history of long-standing gynecomastia. He had no identifiable risk factor for the development of cancer. His pre operative assessment of breast including mammograms was normal. He underwent bilateral subcutaneous mastectomies, with subsequent incidental diagnosis of synchronous bilateral ductal carcinoma in situ. The case was discussed in multidisciplinary team meeting and the need for further surgery was felt including excision of nipple areola complex. However considering patient wishes, cosmetic outcome and recent literature it was decided to preserve nipple areola complex (NAC) with regular follow up evaluation. Our patient at completion of 18 months of treatment is doing well with no signs of local recurrence.
