Abstract
BACKGROUND: Occult nipple malignancy is detected in 0% to 58% of attempted nipple-sparing mastectomies (NSM), prompting excision of the nipple. We report our experience with nipple resection following attempted NSM and our outcomes with subsequent nipple reconstruction. METHODS: An institutional review board-approved retrospective review was performed of attempted NSM cases with immediate implant-based reconstruction from July 2006 to April 2015. Patients who underwent nipple excision were identified. Indications for excision, pathology reports, and reconstructive outcomes were reviewed. RESULTS: Five hundred sixty-eight NSMs were performed in 330 patients. Thirty-four (6%) cases underwent nipple excision, 53% for positive frozen sections, 29% for positive permanent sections, 3% for clinical suspicion, and 15% either at patient request or for symmetry. All of the cases with positive frozen sections had disease on permanent section and 56% had residual disease in the resection specimen. Of the cases with positive permanent sections, frozen sections were negative in 50%, suspicious or atypical in 30%, and not sent in 20% of cases. Thirty percent had residual disease in the resection specimen. Frozen section sensitivity was 64% (or 75% if suspicious and atypical findings are included). There were no false-positive results on frozen section. Sixty-eight percent of cases have undergone nipple reconstruction by CV flap (57%), skate flap (39%), or nipple-sharing technique (4%). The aesthetic result after reconstruction was excellent in 83% of cases. CONCLUSIONS: Our findings support the benefit of intraoperative subareolar frozen section for detection of occult disease. When nipple excision is required, patients can still achieve an excellent aesthetic result with reconstruction.
