Necrolytic acral erythema
Necrolytic acral erythema (NAE) was first described in 1996 by physicians in Egypt, M. El Darouti and M. Abu El Ela. Reports have continued to link hepatitis C with NAE. Necrolytic acral erythema manifests as well-circumscribed, dusky erythematous plaques with adherent scale. While the plaques are psoriasiform, they do not manifest an Auspitz sign as would be seen with psoriasis. Patients with active necrolytic acral erythema report burning or pruritus. It is limited to an acral distribution and, in most cases, is associated with hepatitis C infection. Several cases of necrolytic acral erythema have occurred in patients without hepatitis C. This suggests that necrolytic acral erythema might be a result of zinc dysregulation, rather than a result of hepatitis C infection itself.
