Oral mucosal ulcer

Introduction Oral ulcers, also known as "mouth sores", are superficial ulcers that occur on the oral mucosa. They can vary in size from rice to soybeans, round or oval, and the ulcer surface is concave and concave around the mouth. Irritating foods cause pain and usually heal itself in one to two weeks. Some patients show immunodeficiency, and some patients show autoimmune reactions, that is, due to various factors, the normal immune system of the human body, the immune response to the self-organized antigen, and the destruction of the tissue.

Cause

Modern medicine believes that recurrent oral ulcers are first closely related to immunity. Some patients show immunodeficiency, and some patients show autoimmune reactions, that is, due to various factors, the normal immune system of the human body, the immune response to the self-organized antigen, and the destruction of the tissue. Secondly, it is related to heredity. In clinical practice, the incidence of recurrent oral ulcers has obvious family genetic predisposition. We often see that if one or more parents have recurrent oral ulcers, then their children are more common than ordinary people. More susceptible to illness.

Ulcer-like: On thickened white plaques, there are erosions or ulcers, with or without local irritation, and there may be a history of recurrent attacks and pain. The most common sites of oral leukoplakia are buccal and lip, and the tongue, mouth area, vestibular ditch, sputum, and gums also occur. The most common white spots on the cheeks are often located at the bite line, about 1cm wide, and some extend to the mouth. . At the corner of the mouth 1cm is the lip joint zone, which should be alert to malignant transformation, especially those with Candida albicans infection.

Differential diagnosis

First, the ulcer healing time is distinguished. Benign oral ulcers usually heal in days to weeks, while malignant oral ulcers develop progressively and do not heal for months or even years. Secondly, it can be distinguished by morphology. Benign oral ulcers are generally regular in shape, round, elliptical or linear, with neat edges, clear, clear boundary with surrounding tissues, smoother base of the depression, soft to the touch, and obvious pain. The malignant oral ulcers are irregular in shape, the boundary is unclear, and the edge bulge is uneven. The bottom of the ulcer is uneven, granular, and the texture is hard and tough. It is obviously different from the normal mucosa, and the ulcer pain is not obvious. The third can be distinguished by the course of the disease. Benign oral ulcers often occur repeatedly, with self-limiting, malignant oral ulcers without a history of recurrence, once the disease occurs, it will not heal.
