Anal papillitis mainly manifests as a feeling of foreign body in the anal canal during daily life. With the hyperplasia and enlargement of the papillae, the papillae can prolapse out of the anal canal during defecation. Small papillae can return to the anal canal by themselves after defecation, while large ones need to be pushed back into the anal canal by hand. If not复位 in time, it can cause anal edema and pain. After the enlarged papillae are stimulated or ulcerated, it can cause an increase in anal gland secretion, leading to dampness and itching in the anal area.
Trauma during defecation or anal sinus inflammation can cause acute inflammation of the anal papillae. Due to poor drainage and long-term stimulation by inflammation, the anal papillae become enlarged. After repeated defecation, the anal papillae gradually elongate into pedunculated tumors, resembling rectal polyps.
