ABSTRACT: Thrombotic thrombocytopenic purpura (TTP) is a type of microangiopathic hemolytic anemia that is uncommon in childhood. Adults with TTP have a high mortality rate unless they are treated with plasma exchange. There are few reports of children with acquired idiopathic TTP, and most of those children received some form of treatment. We describe a child with acquired idiopathic TTP who had severe thrombocytopenia and anemia that resolved over several months without the use of any medications. This case suggests that some children with acquired idiopathic TTP might be safely observed without ill effects.
