Acitretin, a metabolite of the aromatic retinoid etretinate, has been utilized successfully in the treatment of psoriasis since the late 1980s. Of the oral retinoids available, etretinate and acitretin are the most likely agents to induce various dose-dependent hair changes, but to our knowledge this is the first reported case of acitretin-induced poliosis. Additional cutaneous findings included skin atrophy and stickiness. Here we report a case of full body acitretin-induced poliosis with concurrent alopecia in a patient with psoriasis. A proposed mechanism for the poliosis is also presented here. Closer examination of retinoid-induced hair changes is needed in order to help physicians better counsel their patients regarding the adverse effects of acitretin and to expand the current knowledge on hair follicle biology.
