Benign ulcerative changes

Introduction Ulcer is a localized defect or ulceration of the skin or mucosal surface tissue. The surface is often covered with pus, necrotic tissue or ecdysis. The scar is left behind, which can be caused by infection, trauma, nodules or tumor rupture. Its size, shape, depth, development process, etc. are also inconsistent. Oral ulcers can be divided into benign and malignant.

Cause

The cause of ulceration is physical stimulation (such as burning, heavy pressure, etc.), chemical stimulation (such as acid, alkali, etc.) or biological stimulation (such as bacteria, mold).

Differential diagnosis

Benign oral ulcers do not develop cancer, and malignant oral ulcers have the possibility of cancer.

1, according to the healing time of ulcers: benign oral ulcers usually heal from days to weeks. Malignant oral ulcers develop progressively and do not heal for months or even more than a year.

2. According to the shape of the ulcer surface: the shape of the benign oral ulcer is relatively regular, round, elliptical or linear, the edge is neat, the boundary with the surrounding tissue is clear, the base of the ulcer surface is smooth, the touch is soft, and the pain is obvious. The malignant oral ulcers are irregular in shape, the edge ridges are uneven, and the boundary between the surrounding tissues is unclear. The base of the ulcer surface is uneven, granular, hard and tough, and has obvious difference from the normal mucosa. The pain is not obvious. .

3, according to the rule of disease rule: benign oral ulcers often occur repeatedly. Malignant oral ulcers often do not recur, and once the onset of the disease does not heal.

4, according to the sensitivity of the drug judgment: benign oral ulcers are generally treated with anti-inflammatory drugs, the effect is obvious, healing faster. Malignant oral ulcers are often treated with such drugs, and the effects are often not obvious.

5, according to the patient's general condition: patients with benign oral ulcers have less systemic symptoms, cervical lymph nodes are not swollen or although swollen but not hard, non-adhesive. Patients with malignant oral ulcers may have fever, cervical lymphadenopathy, loss of appetite, weight loss, anemia, fatigue and other manifestations.

6. Limitation of the skin or mucosal surface tissue, ulceration.
