Abstract

Congenital melanocytic nevus (CMN) is a benign condition that either is present at birth or develops in the first weeks of life. Surgical removal is typically performed to improve cosmetic appearance and reduce the risk of malignant transformation. In this report, we present the case of a 26-year-old woman with a medium-sized CMN on her left breast. The nevus measured 14×8 cm, and the patient desired a single-stage excision. However, this approach would result in a large skin defect that would be challenging to reconstruct using a local flap or skin graft. Moreover, it could potentially compromise the maintenance of natural sagging and the contour of the breast. Consequently, we opted to place a thin thoracodorsal artery perforator free flap following the removal of the CMN. The patient was satisfied with the overall surgical results. By utilizing this free flap for reconstruction, we successfully preserved the natural shape and contour of the breast without complications such as postoperative hypertrophic scarring or contracture at the recipient site.
