Elevated Glucagon in a Patient with Necrolytic Acral Erythema: A Case Report and Review of the Literature

Necrolytic acral erythema (NAE) is a relatively newly described dermatologic disease that is often associated with hepatitis C virus (HCV). Oral zinc therapy is a successful treatment; however, therapy is often delayed due to misdiagnosis. There are limited reports of NAE in the literature. This paper presents a case of NAE in a 68-year-old male with untreated HCV, whose NAE was diagnosed and treated as recurrent cellulitis for 12 years. He had low serum zinc and elevated serum glucagon levels. Elevated glucagon is not often reported in NAE, but the patient’s CT abdomen was negative, ruling out glucagonoma and necrolytic migratory erythema. He improved with oral zinc replacement and was referred to the hepatology department for HCV treatment. This paper additionally presents a review of the literature for NAE cases.
