Аннотация
BACKGROUND: Necrolytic acral erythema is a recently described necrolytic erythema that is unique in its exclusive acral location and strong association with hepatitis C.
OBSERVATION: We report the first case of necrolytic acral erythema in the United States. The patient is a 43-year-old black woman who presented with a 4-year history of tender, flaccid blisters localized to the dorsal aspect of her feet. Serum zinc and glucagon levels were normal. Serum antibodies were positive for hepatitis C, and a liver biopsy specimen showed chronic hepatitis. She was successfully treated with interferon alfa-2b and zinc. We review all previously reported cases.
CONCLUSIONS: Necrolytic acral erythema is a distinct entity. In a review of the literature, most patients were between 35 and 55 years of age, although 1 patient was 12 years old. Five of 8 patients were female. Four of 7 patients described previously were treated with variable success using oral zinc sulfate and amino acids, whereas 2 were successfully treated with interferon alfa. All patients were infected with hepatitis C. Necrolytic acral erythema appears to be a skin disorder linked to infection with hepatitis C virus that responds to treatment with interferon alfa and oral zinc.
