%X Chemical burns are often deep with difficult initial clinical evaluation, especially those due to alkalic agents, which have a strong penetrating power. They therefore require specialized care in a Burn Unit. Self-inflicted burns are infrequent but their management represents a real challenge. We report the case of a 47-year-old referred to our Burn Center for the evaluation of a self-inflicted corrosion with an alkalic agent (soda), injected at the crease of the left elbow. The patient, right handed, was a nurse and had notably a psychiatric history of depressive syndrome. We observed a deep, well-defined necrosis area, associated with intense peri-lesional inflammation and extensive cellulitis. Faced with this unusual clinical appearance for a chemical burn, the patient's questioning was repeated and the patient finally admitted to having injected himself with a basic caustic product intravenously. Surgical treatment was carried out in two stages: debridement with exposure of vascular and neural structures then coverage with a free anterolateral thigh flap. The postoperative consequences were uneventful with a satisfactory functional result. Factitious disorders are underestimated and often misleading. Among factitious disorders, self-inflicted wounds remain a real challenge requiring multidisciplinary management. Many etiologies exist, among which injection of drugs or substances, in any anatomical localization, leading to variable loss of substance. The use of a free flap for acute extravasation is rare but sometimes essential. The anterolateral thigh flap allows good resurfacing on areas with important functional requirements.
