Hypernephroma and associated ureteral involvement.

The propensity of a hypernephroma to invade the renal vein and even the inferior vena cava is widely known. However, in contrast to papillary carcinoma of the kidney, hypernephromas rarely involve the ureter. Review of the English literature reveals 42 reported cases of ureteral involvement. Most represented metastases as opposed to direct, contiguous extension which is extremely rare. C case of hypernephroma with contiguous castlike extension into the ureter without mucosal violation is presented. Mechanisms of ureteral involvement and implications regarding treatment of hypernephromas are discussed.

Fibroepithelial polyps of ureter. A benign ureteral tumor.

The authors believe that it is difficult to differentiate benign from malignant ureteral tumors unless the clinical course or cytologic diagnostics are grossly positive. Therefore, they are of the opinion that unless one's index of suspicion is low, treatment of ureteral tumors should be aggressive unless benignancy is assured. A case in point is reported, and 49 cases of nonepithelial polyps found in the literature are reviewed.
