dry lips
Introduction
Introduction Cheilitis can also have another manifestation of dry lips, chapped, and desquamation. Therefore, dry lips, chapped, and desquamation are also diseases. It is the main feature of dry desquamation cheilitis. Some people are in dry and high temperature. In the case of a knot or environment, there may be cases of dry mouth and desquamation. As long as the appropriate protective agent is applied and the lips are kept moist, it will return to normal without further development. This situation is not considered a disease.
Cause

It is characterized by dryness, desquamation, and cleft palate. Severe performance is swelling of the lips, erosion, inflammatory exudate, blood stasis or purulent formation, pain, and burning sensation. Severe patients may have high fever, muscle and joint pain, headache, cough and other symptoms, and there will be systemic erythematous blister. After blister rupture, the skin will fall off a large area, called "toxic toxic epidermal necrolysis".
Photosensitive cheilitis is more common in the lower lip, lip red erosive, no light yellow exudate over the red edge of the lip, mild swelling of the lip, lip valgus, and even swelling is obvious, bleeding or ulceration, and blood stasis After the skin is peeled off, a bleeding wound is exposed, or there is pus. Local burning, pain, dryness, itching, increased pain due to friction, blocked lip movements, difficult to heal, can be as long as several months or longer, submandibular lymph nodes, local hyperpigmentation, and benign lymphoid hyperplasia The symptoms of cheilitis are similar to those of photosensitive cheilitis, such as erosion, ulceration, pus and blood stasis, desquamation, chapped, pain, swelling and other symptoms. In addition, white short streaks may appear in the red and near mucosa of the lips, similar to discoid lupus erythematosus, but the lesion does not exceed the red lips of the lips, and there is no rash, and the range of lip erosion of the lichen planus is smaller. There must be a white pattern around it. Polymorphic exudative erythema is an acute onset, more common in young people, characterized by erosive bleeding and blood stasis. In addition, for long-term non-healing lip ulcers, the range suddenly increases in a short period of time, and the pain is not serious, the possibility of lip cancer should be ruled out.
Diagnosis
Differential diagnosis
Dry lips need to be identified as follows:
Cleft palate: It is what people usually call "cracks", which often occur in the palms, soles, lips, mouth, and around the anus. It is caused by the dryness or chronic inflammation of the skin, which reduces or eliminates the elasticity of the skin, plus the action of external force. Cleft palate is most common in the foot, sometimes consistent with the texture of the skin, short less than 1 cm, long can be more than 2 cm, deep cleft can cause mild bleeding, pain, usually in the cold season, or in the open air It is common in people who work and who are exposed to fat-soluble and water-absorbing substances.
Desquamation of the skin: It is common in the normal skin surface to continuously keratize and renew, but due to the small number, it is generally not easy to detect. A large amount of skin desquamation in the courseware under pathological conditions.
