The inner lining of the anal canal is the mucosa. Most anal cancers start from cells in the mucosa. Glands and ducts tubes leading from the glands are found under the mucosa. The glands make mucus, which acts as a lubricating fluid. Anal cancers that start from cells in the glands are called adenocarcinomas. The anal canal changes as it goes from the rectum to the anal verge: Cells above the anal canal in the rectum and in the part of the anal canal close to the rectum are shaped like tiny columns. Most cells near the middle of the anal canal are shaped like cubes and are called transitional cells.

References A fissure is a small cut or split in the anoderm Figure 2. It may be induced by a hard bowel movement or straining at stool. Fissures are most commonly located anterior or posterior to the anus. When fissures are found laterally, syphilis, tuberculosis, occult abscesses, leukemic infiltrates, carcinoma, herpes, acquired immunodeficiency syndrome AIDS or inflammatory bowel disease should be considered as causes.
