Oozing from the mouth and lips often occurs in the occurrence of orofacial herpes or labyrinthitis, which is manifested by the initial localized often first burning, itching and flushing. Be aware of viral herpes, eczema, dermatitis, etc. Oozing from the mouth and lips due to herpes oralis is caused by infection with herpes simplex virus; oozing due to labyrinthitis is caused by herpes simplex or eczematous labyrinthitis, etc. The following diseases may cause oral and lip oozing. Causes of oral lip ooze 1, solar labyrinthitis There are two types of acute and chronic acute rare, mostly with a history of strong sunlight exposure, manifested as acute swelling of the lower lip, congestion, followed by erosion, yellow-brown blood crust on the surface, can form superficial ulcers, repeatedly do not heal patients form chronic light labyrinthitis. Chronic cases are associated with long-term exposure to UV radiation, chronic irritation and smoking. The lips are dry, chapped and crusted, often with gray-white discoloration and atrophy, and in long-standing cases the surface is hyperkeratotic, with loss of the red lip margin demarcation line, which can eventually develop into warty nodules. This disease is a precancerous lesion, such as long-term failure to heal, feasible local excision, freezing, fluorouracil or vitamin A acid topical application, but also available CO2 laser treatment. 2, contact labyrinthitis is a local irritation or allergic reaction of the lips due to contact with external chemicals. It is characterized by recurrent clinical attacks, sometimes mild and sometimes severe. It is mostly manifested as acute or chronic labyrinthitis. In the acute phase, the lip mucosa is swollen, blistered and even crusted. In mild cases, there is only localized flaking. In chronic cases, the lips are seen to be infiltrated, hypertrophic, dry and chapped. It can develop into white classes and warty nodules. Chronic contact labyrinthitis has the potential to become cancerous. A patch test should be done if contact labyrinthitis is suspected. If it is a cosmetic lip infection, you need to carefully understand the composition of the cosmetics used to ensure that all allergens are tested, especially some of the more insidious allergens, should be carefully investigated. 3, keratitis is a chronic, symmetrical inflammation of the corners of the mouth. It is often caused by primary Candida albicans and (or) Staphylococcus aureus infection, or secondary infection on the basis of erosion. Clinically, it may show erythema, edema, oozing, crusting, and chapping in the corners of the mouth, and may show granuloma-like changes in long-term orofacial infection. If the patient also has tongue inflammation, riboflavin deficiency should be considered. Dentures, chronic infections, nutritional deficiencies, polysalivation, lip licking, atopic constitution, and other local adverse stimuli are all susceptible factors in the development of keratitis. Therefore, treatment should be provided for different etiologies. 4. Plasmacytoid labyrinthitis is mostly manifested as shiny, red edematous plaques on the lips, which can undergo atrophic changes later and often persist. At the time of diagnosis, there should be evidence of histopathological changes, squamous carcinoma of the lip or mucosal white shift, which may also be accompanied by extensive dermal plasma cell infiltration, but histologically significant interstitial or carcinomatous changes of the epithelium can be seen.
