Azathioprine-Induced Anagen Effluvium: A Case Series of Three Cases

Abstract

Azathioprine is a commonly used drug in dermatology for immunobullous diseases, vitiligo, and lichen planus alopecia areata. Azathioprine is rarely known to cause the acute onset of anagen effluvium (AE) that may precede myelosuppression associated with it. We report a series of three cases of azathioprine-induced AE. All three of our cases were females who were treated with azathioprine for non-dermatological conditions such as neuromyelitis optica, idiopathic thrombocytopenia, and optic neuritis. We report this series mainly due to its rarity.
