Description : The classic pentad of TTP includes hemolytic anemia with fragmentation of erythrocytes, thrombocytopenia, diffuse and nonfocal neurologic findings, decreased renal function, and fever. Congenital TTP, also known as Schulman-Upshaw syndrome, is characterized by neonatal onset, response to fresh plasma infusion, and frequent relapses (Savasan et al., 2003; Kokame et al., 2002).
