Necrolytic acral erythema (NAE) is a rare cutaneous sign of hepatitis C virus infection and has recently been linked to zinc deficiency. It presents as well-demarcated erythematous plaques in a sandal-like distribution on the dorsal feet with psoriasiform epidermal hyperplasia on histology. ⋯ This case supports the association of NAE with both HCV infection and zinc deficiency and highlights the pitfalls in the diagnosis of chronic unrecognized NAE. Suspected cases of NAE should prompt evaluation for underlying HCV and zinc deficiency to avoid treatment delay and associated complications.

Letter Case ReportsErythema ab igne: evolving technology, evolving presentation.

As technology changes, so does the presentation of skin conditions that are related to technology.
