Acquired Platelet Dysfunction with Eosinophilia (APDE) Syndrome: A Case Report.

Acquired platelet dysfunction with eosinophilia (APDE) is a syndrome which has transient state of platelet dysfunction in the presence of marked eosinophilia. This bleeding disorder, otherwise known as "non-thrombocytopenic purpura with eosinophilia", occurs commonly in children from South-East Asia. We report an 11 years old male child, who presented with ecchymotic patches over lower limbs, of recent onset. His hemogram revealed increased eosinophils with a normal platelet count. Coagulation screen revealed normal parameters except increase in bleeding time. Platelet aggregation studies showed normal platelet aggregation with ristocetin, reduced aggregation with ADP and no aggregation was seen with collagen.
