Clinical and histopathological characterization and typing of the human papillomavirus in common warts of kidney transplant recipients.

The prevalence of skin lesions caused by the human papillomavirus (HPV) is high in kidney transplant patients. Twenty recipients of kidney transplants with a diagnosis of common warts were evaluated. HPV detection was performed by polymerase chain reaction (PCR) using the MY09/MY11 and RK91 primers. HPV typing was performed by restriction fragment length polymorphism analysis and direct sequencing. The presence of HPV was identified in 10 patients (50%) and the types identified were HPV-2, 27, 29, 34 and 57.
