[Nephrectomy of a giant hypernephroma (5,150 g)]

We report a giant renal adenocarcinoma (5150 g weight) excised in a 52 years old male. He presented a severe clinical symptoms: serious haematuria, fever (40 degrees C), left flank pain, abdominal discomfort and weight loss (10 kg). The patient underwent left renal artery embolization because of severe anemia (blood transfusion: 4 uu) but haematuria didn't decrease; that's why radical surgery was advised. Until our knowledge this case is the largest removed kidney adenocarcinoma published in the world literature (Medline 1966-2001).
