Ureteral obstruction in a patient with Burkitt's lymphoma and AIDS.

Burkitt's lymphoma presenting as an intrinsic ureteral mass is rare. We report on an immunocompromised patient with hydronephrosis secondary to direct involvement of the ureter by this non-Hodgkin's lymphoma. This case illustrates one of the manifestations of AIDS and the treatment of this manifestation. The relationship of AIDS and its sequela to the genitourinary system is discussed.
