Bladder polyp and heavy proteinuria in a patient with Hodgkin's disease in remission.

A 21-year-old man who developed heavy proteinuria 8 years after remission of Hodgkin's disease treated with MOPP chemotherapy and radiation therapy is reported. Evidence of Hodgkin's disease could not be documented, and minimal changes were revealed by renal biopsy. Proteinuria persisted for 20 months and was followed by dysuria and the discovery of an inflammatory polyp of the bladder. The proteinuria decreased 1 month after excision of the polyp, and disappeared during the following year. Rather than indicating relapse of lymphoma, proteinuria in this patient resulted from a lesion not previously associated with Hodgkin's disease, but possibly resulting from long-term effects of therapy.
