Which clinical feature is part of the pentad of TTP?

The key concept is the classic pentad seen in thrombotic thrombocytopenic purpura: fever, microangiopathic hemolytic anemia with schistocytes, thrombocytopenia, renal impairment, and neurologic symptoms. Fever is part of this pentad, reflecting the systemic inflammatory and microvascular processes at play. The other options—cough, hypertension, and rash—are not defining features of the TTP pentad. Cough isn’t a characteristic finding of TTP, hypertension isn’t a typical part of its classic presentation, and rash is not among the hallmark features. So fever is the clinical feature that belongs to the pentad.
