Necrolytic migratory erythema without glucagonoma in patients with liver disease.

Abstract

Necrolytic migratory erythema (NME) is an uncommon inflammatory dermatosis with a distinct clinical and histologic appearance. NME is usually associated with glucagonoma. Only a few cases of NME in the absence of glucagonoma have been previously reported. We sought to understand further the pathogenesis of NME by analyzing data from three patients. Three patients were examined both clinically and histopathologically. Each patient had an extensive erythematous scaling eruption in intertriginous, perioral, and acral areas, and a markedly red, smooth tongue. Skin biopsy specimens showed confluent parakeratosis, epidermal pallor, papillary edema, and a lymphohistiocytic infiltrate. Two patients had alcoholic liver disease and one had liver dysfunction as a result of hemochromatosis. Serum albumin level was depressed, and liver enzyme values were increased in all three patients. Glucagonoma was undetectable in these patients. In the absence of glucagonoma, hepatocellular dysfunction and hypoalbuminemia appear to be the most common factors associated with NME.
