• Immunosuppressed patients such as renal transplant recipients are prone to increased incidence of wart disease. We examined 48 tissue specimens from 36 renal transplant recipients using human papillomaviruses (HPVs) 1, 2, 3, 4, 5, and 6 in filter hybridization under stringent conditions. The results showed that 90% of the samples contained HPV DNA. Of these 43 positive samples, we found HPV-1 in 2%, HPV-2 in 56%, HPV-3 in 19%, HPV-4 in 47%, HPV-5 in 9%, and HPV-6 in 5%. In several cases, more than one type of HPV DNA was observed. In a few of these cases, the clinical appearance of the lesions differed from what might have been expected, such as those lesions containing HPV-3— or HPV-5—related DNAs.
