Hodgkin's lymphoma: an isolated case of involvement of the ureter

We report the case of a man in which a Hodgkin's lymphoma involved the uret er as the very first clinical situs of the disease. Ureteral involvement in lymphomas is very rare (0.86%-7% and 1%-16%, found in two studies, respect ively, of cases of patients with lymphoma examined post mortem) and when it does occur it is secondary to renal involvement or retroperitoneal adenopa thies. It is by all means exceptional as an isolated situs of disease. Thos e cases reported in the literature as presenting lymphomatous involvement o f the ureter have always been diagnosed as Non-Hodgkin's lymphomas.
