Hypertensive Emergency as the Initial Presentation of Acquired Thrombotic Thrombocytopenic Purpura: A Case Report

Thrombotic thrombocytopenic purpura (TTP) is a type of thrombotic microangiopathy (TMA) related to a deficiency of ADAMTS13 protein, which could lead to fatal outcomes. TTP presents a vast array of symptoms, making its diagnosis a challenge to physicians. In this report, we discuss the case of an 80-year-old male who presented with abdominal pain and hypertension with underlying severe thrombocytopenia and hemolysis. Although his presentation could also be secondary to malignant hypertension, he was promptly diagnosed with TTP based on these findings. TTP is a hematologic emergency, and it should be kept in the differential diagnosis when a patient presents with thrombocytopenia and hemolysis with or without accompanying symptoms.
