title: [Primary retroperitoneal tumors in adults].
abstract: The authors report a series of eight primitive retro-peritoneal tumors, which were difficult to diagnose because of the late appearance of the symptoms. The intravenous urogram is the only satisfactory fundamental examination, possibly completed with ultrasound, CT scanning, and, if necessary, angiography. Extensive surgery allowed total exeresis in most cases. But histological examination remains difficult. Mesenchymomas, the most frequent, are very often malignant. Two cases of association with other malignant tumors were observed. Adjuvant procedures add little to life expectancy and total surgery is alone likely to be effective.
