[Severe toxic dermatitis after injection lipolysis].

The subcutaneous injection of phosphatidylcholine-containing substances is a frequently used method to reduce small localized fat deposits. Even though injection lipolysis is generally safe and free of complications, there have been rare reports on poor results, hematoma, infection or localized skin and tissue necrosis. A 28-year-old woman presented with an extensive toxic dermatitis characterized by well defined, erythematous, partly livid plaques as well as severe edema and strong pain about eighteen days after injection lipolysis on the thighs and knees.
