 Although anal carcinoma is relatively rare, there are many histological types. The reason for this is that the anal canal is situated between the perianal skin and the rectum, which is covered with the anoderm composed of a mixture of various epithelia.

 In addition, there is the cloacogenic zone above the dentate line, originating from the cloaca, and there are the anal glands opening at the dentate line.

 In this paper we will describe the following nine types of anal carcinoma i.e., early anal carcinoma, fistulous cancer, fistulous cancer originating from Crohn's disease, adenosquamous carcinoma, basaloid carcinoma, basal cell carcinoma, extramammary Paget's disease,Bowen's disease, and malignant melanoma, along with their case reports.
