Abstract

Background Correlating human papillomavirus (HPV) type with the clinical and histopathological features of skin lesions (from genital and nongenital sites) can present a diagnostic challenge. Objective In this study, HPV infection patterns were correlated with pathology and clinical presentation in lesional and nonlesional body sites from a young patient with a primary T-cell immunodeficiency. Methods HPV infection was evaluated at both DNA and protein levels by polymerase chain reaction and immunohistochemistry. Results The patient's genital lesions were caused exclusively by α-genotypes (high-risk type HPV-51 in the anal and low-risk type HPV-72 in the penile condylomas). The opposite was true for the skin lesions, which were infected by β-genotypes alone (HPV-8 and HPV-24). HPV-24 was the predominant type in terms of viral load, and the only one found in productive areas of infection. The patient had already developed high-grade dysplasia in the anal condyloma-like lesions, and showed areas of early-stage dysplasia in the lesions caused by the β-genotype HPV-24. Limitations The basic origin of the immunodeficiency is not yet defined. Conclusion These findings provide proof of principle that both α- and β-genotypes can cause overt dysplastic lesions when immunosurveillance is lost, which is not restricted to epidermodysplasia verruciformis.
