On physical examination, the left limb showed a dusky purplish gangrenous-altered skin with ecchymosis, ruptured violaceous bullae and skin sloughing (Figure 1A). A subsequent computed tomography scan depicted gas in the subcutaneous tissue (Figure 1B, arrows). On the first postoperative day after radical debridement of the left limb (Figure 1C), similar skin alterations developed on the right crus (Figure 1D).
