[Necrotizing fasciitis--a frequently mistaken disease (author's transl)].

A case of Fasciitis necroticans on the leg is reported in a female patient, age 28. The disease began with symptoms of an erysipelas, but it was resistant to penicillin. Within a few days necrotic decay of circumscribed skin areas occurred and the adjacent skin was widely undermined by the necrotizing process. Beta-hemolytic streptococci and Staphylococcus aureus haemolyticus were isolated. However, the disease could not be managed by adequate antibiotic therapy. Finally, the process was brought under control by extended incisions and removal of the necrotic masses. Defects were covered by plastic surgery.
