What is your diagnosis?

Thrombotic microangiopathy (TMA) should be considered in this patient with a decrease in urinary output, deterioration of renal function tests, thrombocytopenia, and findings consistent with hemolysis in peripheral blood spread.

Thrombotic microangiopathies describe a group of diseases with clinic of anemia, thrombocytopenia, and acute renal failure. These diseases classified as the name hemolytic uremic syndromes (HUS). The common pathological features in these diseases, endothelial cell injury, microthrombus formation, and multiorgan injury [1].

There are multiple causes of the microangiopathies including Shiga toxin-associated HUS, complement-mediated HUS, thrombotic thrombocytopenia purpura, and other less common causes of HUS (Table 1) [ 1].
