Anal longitudinal folds refer to ridges or folds located inside the anal canal. These folds play a crucial role in the body, contributing to the function of the anal canal and rectum. Sometimes, abnormal growths or masses may develop in this region, leading to discomfort and medical concerns. This article covers the anatomy, types, causes, symptoms, diagnostic tests, treatments, and when to seek medical attention for issues related to anal longitudinal folds and masses.
Anatomy of Anal Longitudinal Folds
- Structure:
- The anal canal is the last part of the digestive system. It is lined with several vertical ridges known as anal columns or longitudinal folds. These are small, raised areas that run along the length of the canal.
- At the base of these folds, there are small pockets or grooves called anal crypts.
- The tissue in this area is highly sensitive and lined with mucous membrane, which helps protect the canal.
- Blood Supply:
- The anal region receives blood from two main arteries: the superior rectal artery (from the inferior mesenteric artery) and the inferior rectal artery (from the internal pudendal artery).
- This rich blood supply helps in the healing process but also makes the area prone to bleeding when irritated or injured.
- Nerve Supply:
- The anal canal is innervated by the inferior rectal nerves, a branch of the pudendal nerve, providing sensation to the area.
- The sensation is necessary for distinguishing between gas, liquid, and solid in the rectum before passing stool.
Types of Masses in the Anal Canal
- Benign Masses:
- Hemorrhoids: Swollen blood vessels that can appear in the lower rectum or around the anus.
- Anal Polyps: Small, benign growths that form on the lining of the rectum or anus.
- Skin Tags: Extra pieces of skin around the anus, often resulting from stretched skin due to hemorrhoids or injury.
- Malignant (Cancerous) Masses:
- Anal Cancer: A rare cancer that forms in the tissues of the anus, often associated with HPV infection.
- Metastatic Tumors: Cancer that has spread from another part of the body to the anal region.
- Other Growths:
- Abscesses: Infected pockets of pus that form in the anal region.
- Cysts: Fluid-filled sacs that can develop in the anal area.
