Initially, the lesion appeared as a full-thickness burn that surrounded the electrode puncture site, with a maximum diameter of 1.5 cm and a charred white necrotic core (Fig. 1A). Then, after surgical debridement of the wound (Fig. 1B), the skin burn was treated with a collagen wound dressing for another two weeks. Overall, although this skin burn took more than one month to heal, its final appearance looked almost like the normal skin (Fig. 1C).
