Highlights Marjolin’s ulcer is usually misdiagnosed. Some theories try to explain the mechanisms of malignant degeneration. Melanoma is rare and aggressive and, once suspected, a biopsy must be done. Deep second and third degree burns must be debrided and covered by a skin graft. Early diagnosis, treatment and vigilance are the keys to success and survival.

Introduction: Electrical burns are potentially devastating injuries and most often occur at the workplace. Scalp defects following electrical burns are a rare occurrence and usually present as a reconstructive challenge. Case Presentation: Male, 31 years old, suffered a high voltage electrical burn at work that resulted in a scalp defect with exposed bone and a third degree burn in the left leg and foot complicated by a compartment syndrome, which needed an emergent fasciotomy and later an amputation below the knee. The scalp defect was covered by a local transposition flap and a skin graft. At 3 months post-operatively flap survived completely with no necrosis or other complications. A satisfactory cosmesis and preservation of scalp contour were achieved. Conclusion: Reconstructive ladder must be respected in reconstruction of these rare and complex defects. Local transposition flaps, if available, are often an ideal choice for scalp reconstruction in that the adjacent tissue is of similar quality to the original defect tissue with a long-term durability, contour preservation, minimal donor site morbidity and an acceptable cosmesis.
