Acquired Thrombotic Thrombocytopenic Purpura in the Presence of a Urinary Tract Infection: A Rare Pediatric Case.

Thrombotic thrombocytopenic purpura (TTP) is a type of microangiopathic hemolytic anemia that rarely presents in the pediatric population. This life-threatening disorder manifests as severe consumptive thrombocytopenia and disseminated micro-thromboemboli, leading to organ ischemia. Here, we present a case of an acute first-time episode of acquired TTP in a 17-year-old African American female with a past medical history of obesity, recurrent urinary tract infections, and dysfunctional uterine bleeding managed with oral contraceptives.
