The Case | A 69-year-old man with purpura and acute renal failure

A 69-year-old man was referred to our department because of acute renal failure. Three months prior, he was diagnosed with rectal adenocarcinoma, which was revealed by digestive bleeding and altered general status. The patient was treated by radiotherapy and chemotherapy using capecitabin. On admission, blood pressure was 105/70 mm  Hg and temperature was 36°C. Skin examination showed bilateral leg edema and a striking purpura (Figure 1). Laboratory investigations revealed acute renal failure with increased serum creatinine at 409 μmol/l against 86 μmol/l 6 months before.
