A Case of Bullous Pemphigoid Induced by Ingestion of Rhus [옻 섭취에 의해 유발된 유사천포창 1예]

초록

Rhus is a common cause of allergic contact dermatitis (ACD), particularly in East Asia. Rhus can cause localized contact dermatitis following direct contact with the skin, and systemic contact dermatitis following its ingestion, causing pruritus, erythema, and occasionally blistering. Bullous pemphigoid (BP) is an acquired subepidermal autoimmune bullous disease that typically occurs in the elderly. Although BP usually occurs sporadically, some precipitating factors of BP have been suggested, such as other autoimmune diseases, drugs, and malignancies. We report a rare case of BP induced by ingestion of Rhus in a 54-year-old man who presented with itchy erythematous rash and blisters on the whole body, initially misdiagnosed as ACD, and treated with systemic steroids. © 2020 Korean Dermatological Association.
