Thrombotic thrombocytopenic purpura presenting as bilateral flank pain and hematuria: a case report.

ABSTRACT

Thrombotic thrombocytopenic purpura (TTP) is a rare disease whose incidence is now increasing. We present a case of a 37-year-old man who presented with bilateral flank pain and hematuria, subsequently diagnosed with TTP. Thrombotic thrombocytopenic purpura has classically been characterized by the pentad of fever, microangiopathic hemolytic anemia, neurologic symptoms, renal dysfunction, and thrombocytopenia. The pathogenesis of the disease has been a mystery until recently. We review the current literature regarding the pathophysiology and management of this disorder. Our discussion focuses on the importance of understanding this disease while considering the differential diagnosis of a patient presenting with anemia and thrombocytopenia because the common pitfall of rapidly administering platelets to a patient with TTP may lead to a disastrous outcome.
