Acquired platelet dysfunction with eosinophilia in white children.

Acquired platelet dysfunction associated with eosinophilia has been described mainly in indigenous Southeast Asian and East Indian children. We describe two white boys in whom this disorder developed after they had lived in Malaysia for 12 to 18 months. Acquired platelet dysfunction associated with eosinophilia should therefore be considered in children who, after a visit to this region, have easy bruising and esoinophilia.
