idiopathic purpura

idiopathic purpura
idiopathic thrombocytopenic purpura, immune thrombocytopenic purpura a type of thrombocytopenic purpura that is not directly associated with any definable systemic disease but often follows a systemic infection; it has been found to be an autoimmune condition, caused by antigens against platelets, resulting in ecchymoses, petechiae, and other bleeding. There are both acute and chronic forms: the acute form has a sudden onset, is more common in children, and usually resolves spontaneously within a few months; the chronic form has a slower onset, is more common in adults, and may be recurrent.
