[Clinical comments on a case of retroperitoneal lipoma]

The authors show a case of retroperitoneal lipoma, histologically ascertained; they state its origin and the clinical features, and analyse the different diagnostical methods, particularly dwelling upon urography, TC and selective arteriography. They, at last, point out such pathology, although benign, is burdened by a high risk of relapses and by the possibility to turn into malignant. As a conclusion, they assert the importance of the radicalness of the intervention, joined to bioptic drawings in different parts of the tumor extirpated, with the purpose to identify, as precociously as possible, an eventual malignant degeneration of the same lipoma.
