Zusammenfassung

Die anale intraepitheliale Neoplasie (AIN) ist eine histologische Diagnose für Dysplasien im analen Plattenepithel. Sind diese Dysplasien auf das untere Drittel des Epithels beschränkt, werden sie AIN ersten Grades oder Low-grade-AIN (LGAIN) genannt, sind das mittlere und obere Drittel dysplastisch durchsetzt, AIN zweiten oder dritten Grades (High-grade-AIN [HGAIN]). Auslöser ist meist eine Infektion mit dem humanen Papillomavirus (HPV). Unbehandelt kann die AIN invasiv wachsen. Risikofaktoren für AIN sind u. a. Rauchen, Immunsuppression, Human-immunodeficiency-virus-Infektion, Condylomata acuminata, intraepitheliale Neoplasien und HPV-assoziierte Tumoren in der Anamnese. Eine AIN kann sich klinisch unauffällig zeigen, aber auch als Dermatose. LGAIN bzw. Condylomata acuminata sind leitliniengerecht zu behandeln. Bei HGAIN stehen chirurgische, ablative und topische Therapiemodalitäten zur Verfügung. Rezidive sind häufig, weswegen bei HGAIN eine Nachsorge erfolgen soll.
