An improbable and unusual case of thrombotic thrombocytopenia purpura.
Thrombotic thrombocytopenic purpura (TTP) is a life-threatening medical emergency which may be difficult to recognize given the wide spectrum in which it presents. A delay in treatment may be catastrophic as untreated cases of TTP have a mortality rate exceeding 90%. Given the high fatality rate of untreated TTP and its range of presenting symptoms, we present our unusual case of TTP in a post-splenectomy patient with early treatment and positive outcome. This case describes a 54-year-old female who presented with hematuria and gingival bleeding, followed by the development of a bilateral lower extremity petechial rash. Her past medical history was significant for multiple episodes of TTP, the last of which resulted in a splenectomy and a 20-year history of remission thereafter. On exam, she was alert, well appearing, and neurologically intact. Her only significant finding was a bilateral lower extremity petechial rash. Laboratory studies revealed mild anemia and thrombocytopenia, an elevated lactate dehydrogenase, and a decreased haptoglobin. Peripheral smear showed poikilocytosis, helmet cells, and schistocytes. Corticosteroid therapy was promptly initiated, her platelets were monitored closely, and she underwent urgent therapeutic plasma exchange. Due to the risk of significant morbidity and mortality that may result from delayed treatment of TTP as well as the significant variations of presentation, TTP requires a consistently high index of suspicion. Our patient suffered multiple relapses of TTP within a 30-year span, underwent splenectomy in early adulthood, and presented with atypical symptoms during her most recent relapse illustrating how persistent TTP can be as well as how unusually it may present. Providers should be aware of the vast spectrum of presentation and remember that TTP may recur following splenectomy despite prolonged remission.
