Anal dysplasia is a pre-cancerous condition which occurs when the mucosa lining of the anal canal undergo abnormal changes. During this condition, lesion, or visible pattern of clustered abnormal cells, appear. These cells may then progress from low-trade lesions to high-grade lesions.

Because of these abnormal cells, the anus extends from within the body and joins the rectum, forming an anal canal within the body. Symptoms include anal warts in and around the anus.

Causes

Anal dysplasia is most commonly linked to human papillomavirus (HPV), a usually sexually-transmitted disaease.
