[Multiple renal masses as a complication in a patient with Hodgkin's disease in remission. Recurrence or primary tumor?].

A forty-eight year old man with Hodgkin's disease in complete remission after 8 cycles of polychemotherapy (COPP) is presented. In an abdominal tomography, practiced 18 months after completion of treatment, two masses were found on the left kidney. Differential diagnosis between a Hodgkin's recidive and a second primary tumor and the implication of Hodgkin's treatment in the appearance of other neoplasms are discussed. Literature is reviewed.
