Other names: Immune Thrombocytopenic Purpura; ITP
Idiopathic Thrombocytopenic Purpura is a systemic illness characterized by ecchymoses (extensive purplish patchs caused by extravasation of blood into the skin) and hemorrhages from mucous membranes and very low platelet counts. It results from platelet destruction by macrophages due to an antiplatelet factor.
