[Ulceration of the skin in necrobiosis lipoidica (author's transl)].

As a supplement to earlier investigations, a case of a 46 year old female patient is reported who has suffered from necrobiosis lipoidica granulomatosa with ulceration for 17 years. A marked remission was obtained by treatment with anti-inflammatory and immunosuppressive therapy. It is pointed out that under the usual treatment when ulcers of the lower leg and other areas of the skin do not heal, after exclusion of malignancies, necrobiosis lipoidica diabeticorum or necrobiosis lipoidica granulomatosa must be considered, especially as prophylactic examinations may arise.
