BACKGROUND: 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. OBJECTIVE: We sought to understand further the pathogenesis of NME by analyzing data from three patients. METHODS: Three patients were examined both clinically and histopathologically. RESULTS: 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. CONCLUSION: In the absence of glucagonoma, hepatocellular dysfunction and hypoalbuminemia appear to be the most common factors associated with NME.
