We present two cases of Limberg flap reconstruction after mastectomy. Case 1: A 70-year-old woman had a breast cancer in the upper half of the right breast measuring 6 cm in diameter, with skin invasion. Preoperatively, she received four courses of chemotherapy with epirubicin and cyclophosphamide. She then underwent an Auchincloss operation followed by Limberg flap reconstruction. A rhombus 10 cm on each side was designed to cover the area of skin invasion and the nipple. After the Auchincloss procedure via the rhomboid incision, the Limberg flap was raised and rotated from the inferomedial aspect of the defect. Primary closure was feasible and the flap engrafted easily. Case 2: A 65-year-old woman with a breast cancer, 2 cm in diameter, at the mid outer part of the left breast underwent partial mastectomy with sentinel lymph node biopsy, followed by Limberg flap reconstruction. A rhombus 3 cm on each side was designed to cover the tumor. After resection of the tumor via the rhomboid incision, the Limberg flap was raised and rotated from the inferolateral aspect of the defect. Postoperatively, there was minimal breast deformity, and the scar was minimally visible.
