[Hypereosinophilic syndrome (leukemoid eosinophilia) with a dermal exanthematous vesiculo-bullous manifestation].

The reported disease of a 12 year old girl, characterized by mostly vesico-bullous skin alterations and a marked blood-, bone marrow- and tissue eosinophilia, is ascribed to eosinophilia leukemoid. The problems of separating acute eosinophilia leukemica from other causes of hypereosinophilia will be discussed in detail. Therapy with prednisolon caused regression of the skin alterations and disappearance of the eosinophilia.
