Necrobiosis Lipoidica Diabeticorum of the Scalp: A Case Report

Necrobiosis lipoidica diabeticorum (NLD) is a rare chronic and granulomatous skin disorder that affects 0.3% of diabetic patients. Although the etiology and pathogenesis of NLD is still contraversial, it is thought that microangipathy has an important role. The legs are the most common site for NLD, but involvement of other areas such as the abdomen, upper extremities and scalp have been reported. We present a case of scalp and leg NLD which was diagnosed on the clinical and histopathological basis. (Iran J Dermatol 2009; 12: 93-95)
