If repeated episodes or long-term unhealed, the lips are thick, infiltrated, dry, desquamated or cleft. The part is roughly the same as the contact area. basic knowledge The proportion of illness: the incidence rate is about 0.0005%-0.0008% Susceptible people: no special people Mode of infection: non-infectious Complications: phlegm

Contact cheilitis check

Laboratory and other examinations: Pathological examination of chronic cheilitis showed non-specific inflammatory manifestations, mucosal epithelial keratosis or hyperkeratosis, exfoliative defects, normal intraepithelial cells or edema degeneration. There is a small amount of neutral or eosinophil infiltration in the epithelial layer. The spinous layer can be thickened. Vascular dilatation and hyperemia are seen in the lamina propria and submucosa, and a large number of dense lymphocyte infiltrations are seen.

Diagnosis and diagnosis of contact cheilitis

There is a clear history of exposure, with localized acute eczema-like changes.

It should be differentiated from the following two types of cheilitis:

1. Exfoliative cheilitis: The main features of redness, erosion, cleft palate and desquamation of the lip mucosa are mild and heavy, and they are not cured for a long time. The disease may be caused by the wind, fire, poison, and evil spirits; or because of the spicy and thick taste of the food, the spleen and stomach are hot and humid, and the lips are burned; or the skin is caused by blood and dryness.

2. Actinic cheilitis: caused by ultraviolet allergy in sunlight. The severity of the symptoms is related to the patient's sensitivity to light, the intensity of the light, the length of the exposure, and the range of exposure. For those who are sensitive to sunlight, after exposure to sunlight, in addition to the formation of melanin, intracellular and extracellular edema, collagen fiber degeneration, etc. occur.
