Thrombotic thrombocytopenic purpura with typical pentalogy in a child: a case report and literature review

Thrombotic thrombocytopenic purpura (TTP) is a rare and life-threatening thrombotic microangiopathy with clinical quintuple symptoms, including fever, thrombocytopenia, microangiopathic hemolytic anemia, neurological symptoms, and renal insufficiency. TTP onset in children is rare, and the percentage of acute TTP with these five symptoms at the same time is <10%. In this study, we reported a typical case of TTP onset in a child with clinical quintuple symptoms.
