title: Association of renal xanthogranuloma and urological neoplasia.
abstract: Seven of 66 cases of renal xanthogranuloma (RXG) were associated with urinary tumors (10.6%). The diagnostic and surgical problems can be difficult because of the similarities to a neoplasm and because of the inflammatory nature of RXG. Obstruction and infection seemed to be causative factors in 5 of the 7 cases. It was not possible to demonstrate an immunological deficit in these patients. A review of the literature shows the rarity of this association: 20 cases together with our 7 cases gives a total of 27 out of the 676 cases of RXG that have been published (an incidence of 4%).
