Nonthrombocytopenic Idiopathic Purpura
📋Overview
Nonthrombocytopenic idiopathic purpura is a legacy term historically used to describe purpura (purple skin spots due to bleeding under the skin) occurring without a low platelet count and without an identifiable cause. In modern clinical practice, purpura without thrombocytopenia is evaluated based on underlying causes such as vasculitis, coagulation disorders, or connective tissue diseases rather than being labeled idiopathic. Therefore, this term corresponds broadly to nonthrombocytopenic purpura of unclear origin, but current diagnosis focuses on identifying specific causes of purpura with normal platelet counts.
