Abstract: 【Abstract】 Objective To evaluate clinical efficacy of bipedicled scrotal flaps combined with keystone-design perforator island flaps in repairing postoperative large-area defects in male patients with extramammary Paget′s disease of the perineum. Methods Clinical data were collected from 6 male patients with extramammary Paget′s disease of the perineum in Dermatology Hospital of Jiangxi Province from February 2018 to March 2019, and analyzed retrospectively. These patients were aged from 70 to 84 years （median, 77.5 years）, skin lesions involved the mons pubis, penis and scrotum, and the area of postoperative skin defects varied from 18 to 133 cm2 （median, 96 cm2） in size. In all patients, mons pubis defects after tumor resection were repaired with abdominal keystone-design perforator island flaps, and scrotal and penile defects were repaired with bipedicled scrotal flaps using the remaining scrotal tissues. These patients were followed up at 1 and 3 months after surgery and every 3 months thereafter. Results All the 6 patients were followed up for 3 - 36 months, with an average of 10 months. All flaps survived with a good color and texture match, and favorable function and appearance were achieved in both the donor and recipient sites. Conclusions The bipedicled scrotal flaps combined with keystone-design perforator island flaps can repair postoperative large-area defects in male patients with extramammary Paget′s disease of the perineum. Moreover, the operation is simple, and good blood supply can be achieved.
