ABSTRACT
Pyoderma gangrenosum is a necrotizing skin disease of unknown etiology. The lesions
are painful and occur mostly on the lower extremities, either single or multiple,
but can appear in any region of the body. The authors report a case of pyoderma gangrenosum
involving bilateral skin lesions over the anterior surface of the legs in a 13-year-old
male patient. The lesions presented with ulcerative colitis, which is one of the most
commonly associated diseases of pyoderma gangrenosum. After examination, systemic
immunosuppressive treatment was administered and the progression of the disease was
controlled. The lesions were treated with the simultaneous application of two free
anterolateral thigh fasciocutaneous flaps after radical debridement. The procedure
was successfully performed and no recurrence was observed. Although microvascular
free tissue transfer cannot be performed in a standard fashion in pyoderma gangrenosum
cases because of the risk of pathergy response, it should be considered as a surgical
option in selected cases, otherwise difficult to manage, with the simultaneous application
of appropriate systemic medical treatment.
