Successive urinary papillomavirus excretion, condylomata acuminata and urogenital epithelial malignant disease after renal transplantation.

Of 3 renal allograft recipients who were found to excrete papillomavirus in the urine, 1 has since developed a condyloma, 1 a condyloma and a keratinizing squamous carcinoma and 1 a transitional cell carcinoma. Peroxidase-antiperoxidase staining has confirmed the presence of papillomavirus antigen in the condylomas. The significance of these findings is discussed.
