Fournier's gangrene can lead to extensive defects of the perineoscrotal area with exposure of the testes. Such defect poses challenging tasks for both functional and cosmetic reconstruction. Due to its proximity, medial thigh skin appeared to be the most versatile donor site for perineoscrotal reconstruction. In this report, we present a case of reconstruction of a large perineoscrotal defect because of Fournier's gangrene using a posteromedial thigh (PMT) perforator propeller flap. A 58 year-old male who suffered from Fournier's gangrene resulted in a scrotal defect of 10 × 12 cm(2) with a large dead space. A pedicled PMT propeller flap measuring 9 × 23 cm(2) with two perforators that originated from the profunda femoris artery (PFA) was harvested for scrotal defect reconstruction and dead space obliteration. The flap survived completely, with no recipient or donor site morbidity. The length of followup was 3 months and was uneventful. The pedicled PMT propeller flap may be considered as a valid option for perineoscrotal reconstruction.
