[Clinical analysis of 200 cases of idiopathic thrombocytopenic purpura].

Background: Idiopathic thrombocytopenic purpura is characterized by extravasation of blood into the subcutaneous tissue, mucous membranes or skin; it generates bleeding manifestations as ecchymotic lesions, petechiae of sudden onset, epistaxis, bleeding from the gums, and serious complications such as intracranial hemorrhage. This condition is due to a platelet destruction mediated by antibodies directed against the surface of the platelets. The objective is to present the clinical characteristics of patients with idiopathic thrombocytopenic purpura in a third level medical facility in Puebla, México.
