Breast carcinoma in residual breast tissue after prophylactic bilateral subcutaneous mastectomy

We report a case of breast carcinoma 6 years after a prophylactic subcutaneous mastectomy. The incidence of breast carcinoma after prophylactic mastectomy is probably less than 2%. If removal of breast tissue is performed to prevent breast cancer, we advocate a complete simple bilateral mastectomy, including nipple-areola complex, axillary tail and pectoral fascia.
