Thrombotic thrombocytopenic purpura associated with COVID-19 in a critically ill child: a Peruvian case report.

Background: Acquired thrombotic thrombocytopenic purpura (TTP) is a rare disease. In middle and low-income countries, specific resources are required for its diagnosis due to the lack of diagnostic tests and the variable response to plasma exchange, especially in the context of the new SARS-CoV-2 pandemic.

Case Report: We report the case of a 9-year-old male Hispanic patient with SARS-CoV-2 infection, atypical presentation, and multisystem involvement, thrombotic microangiopathy with dermal manifestations, hematologic, renal, and neurologic involvement.
