Aesthetic unit boundary approach to large fibroadenoma resection

Background Fibroadenomas are the most common benign breast tumors in adolescents. Surgical excision is indicated when the tumor becomes large or symptomatic. Multiple approaches have been described. However, unsightly scars, excess skin, and breast asymmetry are common challenges after tumor resection. The aims of our study were to describe a concentric circumareolar approach combining the round-block technique and geometric principles in the management of large benign breast tumors. Methods This was a retrospective review of pediatric patients who have undergone excision of large fibroadenoma with concentric circumareolar approach from June 2007 to May 2017. Preoperatively, the excess skin that needed to be resected was marked based on geometric principles. Under general anesthesia, circumareolar deepithelialization of the excess skin and tumor resection were performed. Purse-string suture technique was used to achieve the proper nipple-areola complex size. Results Satisfactory breast symmetry and minimal scarring were achieved in all 6 patients. One patient developed a small seroma, which resolved spontaneously without intervention. Conclusions Concentric circumareolar approach can be used to resect large benign breast tumors while concealing the scar along the aesthetic unit boundary of the breast. The cosmetic outcome and recovery were promising. The approach is simple to execute, highly reproducible, and less dependent on intuition.
