The reconstruction of defects of the perianal area and vagina places a high demand on a reconstructive surgeon. Different reconstructive methods include a skin graft, a local skin flap, a musculocutaneous flap, and a pedicled perforator flap. Here, we report the case of a 59-year-old female patient with a pelvic defect, who underwent reconstruction with a quadruplet combination of pedicled flaps from the medial thigh, due to an extensive resection of a recurrence of a squamous cell carcinoma of the anus, vulva, and partially the colon. The surgical oncologist performed a rectum amputation, a partial colectomy, a complete hysterectomy, and a resection of the dorso-lateral vaginal vault in order to achieve tumor-free margins. The resulting defect measured 14 × 11 cm2 with 8 cm of deep space. The defect was covered and reconstructed by employing a bilateral pedicled gracilis muscle flap rotated about 120° and advanced to fill up the residual spare space in the deep and a bilateral vertical posteromedial thigh (vPMT) using a propeller flap measuring 27 × 10 cm2 rotated 180° in order to reconstruct the vagina and the perianal area. All flaps survived without major post-operative complications. The donor site morbidity was minimal. The range of motion was not limited over both hip and knee joints. Patient had no problem with urination. Sexual intercourse was not highly considered due to patient’s old age. The follow-up at 6 months showed acceptable cosmetic results with a satisfying contour of the coverage and reconstructed area. The combination of pedicled gracilis muscle flap and vPMT propeller flap may represent a valuable option in such a defect where deep space obliteration and reconstruction of the vagina with perianal contouring are needed.
