platelet disorders

A range of disorders that includes intrinsic platelet abnormalities, both congenital and acquired, and the disorders caused by a deficiency of platelets (thrombocytopenia) or an excess (THROMBOCYTOSIS). Several syndromes include thrombocytopenia, platelet membrane disorders or giant platelets. Platelet disorders may be of genetic origin or may be acquired and may involve reduced platelet production or increased platelet consumption.
