thrombocytopathy

any of several blood disorders characterized by dysfunctional platelets (thrombocytes), which result in prolonged bleeding time, defective clot formation, and a tendency to hemorrhage. Inherited thrombocytopathies include von Willebrand disease; thrombasthenia, characterized by abnormal clot retraction and defective platelet aggregation; and Bernard-Soulier syndrome, characterized by unusually large platelets. In addition, thrombocytopathy is sometimes seen in cases of Down syndrome and Wiskott-Aldrich syndrome (an immune disorder).
