Intravenous immunoglobulin G use in patients with chronic inflammatory demyelinating polyneuropathy: An uncommon cause of drug‐induced discoid lupus erythematosus

Abstract

Drug‐induced chronic cutaneous lupus erythematosus, or drug‐induced discoid lupus erythematosus, is a rare cutaneous phenomenon. Various medications have been associated with drug‐induced discoid lupus erythematosus including fluorouracile agents, especially tegafur and uraciltegafur, and TNF‐α antagonists such as infliximab or etanercept. Recent literature has described a case series of six patients receiving IgG immunoglobulin for chronic inflammatory demyelinating polyneuropathy with subsequent presentations of discoid lupus erythematosus. We present a patient with chronic inflammatory demyelinating polyneuropathy who developed discoid lupus erythematosus secondary to IgG immunoglobulin.
