Multicentric epidemiological non-comparative study in France characterising evolution of anal Human papillomavirus (HPV) infection and related lesions and evaluating markers associated with the observed evolution. Estimated enrolment: 500 Principal Outcomes * Detection of high-grade cytological and histological anal lesions by high resolution anoscopy * Spontaneous regression of high-grade anal lesions * Detection of anal HPV infection Intervention (procedure): * Patient medical interview (initial inclusion visit, Month 12 and Month 24 follow-up visits and if applicable Month 6 and Month 18 control visits) * Standard proctologic examination with digital rectal examination and 2 anal swabs (initial inclusion visit, Month 12 and Month 24 follow-up visits and if applicable Month 6 and Month 18 control visits) * High resolution anoscopy (initial inclusion visit, Month 12 and Month 24 follow-up visits and if applicable Month 6 and Month 18 control visits) Only if lesion suggestive of Anal Intraepithelial Neoplasia (AIN) detected during High Resolution Anoscopy (HRA): \- anal biopsy(ies) during HRA Only if high-grade lesion: \- HRA biannually
