Anal cancer is a rare type of gastrointestinal malignancy. Over 80% of anal cancers are of squamous origin and arise from the squamous epithelium of the anal canal and perianal area. Recent evidence has demonstrated that the incidence of squamous cell carcinoma of anal cancer increases in immunocompromised patients. Approximately 10% are adenocarcinoma

Anal stenosis can be anticipated after more extensive excisions of the anoderm, and they may occur in extensive condylomata and after excision of the Buschke-Loewenstein tumor, although the most common cause is hemorrhoidectomy.

Radical radiation therapy is capable of eradicating the primary tumor and yielding a high survival rate.
