Extramammary Paget's disease (EMPD) is a rare intra-epidermal adenocarcinoma, and reconstruction of the penoscrotal region remains a clinical challenge. The superficial circumflex iliac artery perforator (SCIP) flap has been successfully used as a free flap, while its application as a propeller flap in the reconstruction of penoscrotal EMPD defect is rarely reported. The objective was to evaluate the safety and efficacy of the SCIP propeller flap in the reconstruction of penoscrotal defects in EMPD. Between September 2010 and August 2022, consecutive patients diagnosed with penoscrotal EMPD were enrolled. All patients underwent penoscrotal EMPD excision and reconstruction with SCIP propeller flap combined with other flaps or skin grafts on individual defects. Demographic information, surgical parameters, postoperative complications, patient satisfaction, and recurrence rates were analyzed. Twenty-four patients (mean age, 73 ± 8.8 years; mean BMI, 23.98 ± 3.62 kg/m2) with 33 SCIP propeller flaps (mean size 120.1 cm2; range, 24-208 cm2) were included, and the mean defect size was 67.4 cm2 (range, 12-255 cm2). The mean operative duration was 385.4 ± 146.8 min. Fifteen patients received autologous full-thickness skin grafts, and four received other flaps simultaneously. All flaps survived without total or partial loss, and all donor sites achieved primary closure, though local hematoma (one case) and limited skin graft necrosis (two cases) were observed. All patients experienced complete wound healing and maintained penoscrotal morphology and function without recurrent lesions over a mean follow-up of 59 months. The SCIP propeller flap seems a safe and effective reconstructive method for penoscrotal EMPD. IV.
