High Resolution Anoscopy: Procedure and findings

High Resolution Anoscopy (HRA) using a colposcope or operating microscope with 5% acetic acid and Lugol ′s solutions was developed to identify abnormal epithelial changes such as high-grade squamous intraepithelial lesions (HSIL) and other lesions associated with human papillomavirus (HPV). It is hypothesized that targeted treatment of HSIL will prevent progression to cancer. HRA has become more acc epted in clinical practice especially for populations considered at-risk for anal cancer including those who are immunocompromised and men who have sex (MSM).
