title: [A case of drug eruption induced by hydroxyzine pamoate].
abstract: A 62-year-old woman with rheumatoid arthritis, Basedow's disease and arrhythmia has been treated with antirheumatic, antiarrhythmic drugs and so on. She developed pruritic diffuse erythema with papules on the trunk and extremities 2 days after taking hydroxyzine pamoate for asteatotic eczema. Laboratory data showed increased levels of eosinophils. Histopathological examination revealed a infiltrate of inflammatory cells in the upper dermis. Patch tests with hydroxyzine pamoate and hydroxyzine hydrochloride were positive. From these findings, we diagnosed this case as drug eruption due to hydroxyzine. Her eruption subsided after she discontinued hydroxyzine pamoate and other drugs which were started within 5 days before the onset of the eruption and was treated with systemic steroid, systemic antiallergic drug and topical steroid.
