O Papilomavírus Humano tem alta incidência na população. O objetivo deste trabalho é o estudo dos resultados encontrados no exame anatomo-patológico e no PCR das formas clínica e subclínica da infecção anal por HPV em quatro grupos de pacientes. MÉTODO: Foram estudados 10 pacientes com prurido anal idiopático, seis com infecção genital pelo HPV, tratada, seis com condiloma anal tratado e oito com condiloma anal. As verrugas foram biopsiadas nos oito pacientes com condiloma e feito exame de anuscopia de alta resolução com biópsia dirigida nos outros 22 pacientes. O material foi encaminhado para exame anátomo-patológico e depois, a partir do mesmo bloco de parafina, foi feito o exame de PCR. Resultados: O anátomo-patológico foi positivo para HPV em todos os pacientes, sendo que nos oito com condiloma confirmou-se a forma clínica e em 22 diagnosticou-se a subclínica com 13 casos de neoplasia intraepitelial associada. O PCR foi positivo em 91,9% dos 22 pacientes da forma subclínica ao anátomo-patológico e em 87,5% dos oito pacientes da forma clínica. O tipo predominante nos casos de HPV anal subclínico foi o 16 e o predominante nas verrugas foi o 11. CONCLUSÕES: O exame anátomo-patológico foi positivo para HPV em todos os pacientes, propiciando também o diagnóstico de 13 casos de neoplasia intraepitelial, sendo dois de carcinoma "in situ". O PCR foi positivo em 91,9% dos pacientes da forma subclínica ao anátomo-patológico e em 87,5% da forma clínica ao anátomo-patológico. O tipo predominante da forma subclinica foi o 16 e das verrugas foi o 11. The purpose of this study is to analyze the results found in the pathological examination and PCR test for clinical and subclinical HPV anal infections in four groups of patients. Methods: The four groups studied were: ten patients with idiopathic anal pruritus, six with treated HPV genital infection, six with treated anal condyloma, and eight with anal condyloma. Eight patients with condyloma underwent wart biopsy, and high-resolution anoscopy with directed biopsy was performed in the remaining 22 patients. Paraffin wax embedded biopsy specimens were sent to pathological analysis, and later PCR was carried out on the same samples. Results: Through the pathological examination, the presence of HPV is positive in all patients studied: clinically in the eight patients with condyloma, and subclinically in the others 22. Thirteen of these 22 patients presented and associated intraepithelial neoplasia. PCR was positive in 91,9% of the 22 patients those who presented the subclinical infection at pathology examination and 87,5% of the eight patients that presented the clinical infection the most common type of anal subclinical HPV infection was HPV-16 and HPV-11 when warts were presented. Conclusions: Pathological findings related to HPV were presented in all patients studied, and 13 cases were diagnosed two of them were carcinoma in situ. PCR was positive in 91,9% of patients presenting the subclinical infection, and in 87,5% with the clinical infection was HPV-16, and for warts HPV-11
