Thrombotic microangiopathy with severe renal failure in adenocarcinoma

Kidney disease frequently complicates malignancy and its treatment. The spectrum of renal disease in cancers includes acute kidney injury, chronic kidney disease and tubular disorders. Thrombotic microangiopathy (TMA) is an uncommon initial clinical presentation of malignancies. Renal failure is an extremely rare feature of cancer-associated TMA syndromes in the absence of chemotherapy. Here, we report a patient who presented to the hospital for the first time with TMA and severe renal failure requiring hemodialysis and was diagnosed with gastric adenocarcinoma.
