Erosion is the loss of epithelial covering the mucosa or skin, which does not reach the deeper layers. dermatological lesions include it into the secondary cutaneous condition. The etiology of their formation are multifaceted - remains of the original lesions descent, corrosive and irritants agents, infection, cancer and other morphological abnormalities. The presence of erosions is disorder of the existing defense barrier, which results in an increased risk of various infections. Some types of erosion are states of pre-cancerous and untreated can lead to the development of cancer (e.g. erosion of the cervix).

Types depending on location

a) gastric erosion - this is a loss of gastric mucosa but not exceeding the muscle layer (not gastric ulcer). Symptoms are similar to those of peptic ulcer disease (retrosternal pain, increasing in periods starvation). The occurrence of large amounts of gastric erosions was called hemorrhagic gastritis - present at the mucosal surface bleeding changes, which further intensifies already existing inflammation. Diagnostic method: gastroscopy with biopsy (the presence of Helicobacter Pylori). treatment of proton pump inhibitors (inhibit gastric acid secretion; creation correct environment for healing). In the case of the presence of H. Pylori, also enable eradication therapy.

b) aphthae - erosions of mucous membrane surrounding the mouth, tongue and lips. Changes are accompanied by inflammation and pain. They tend to recur and their cause has not been determined - on their development affects chemicals added to foods and to toothpastes, states of malnutrition in the body (avitaminosis B12, folic acid deficiency , stress, mechanical trauma (accidental or intentional), abnormal immune system (allergies, AIDS), hormonal disorders, use of strong antibiotics, leukemia, family predisposition. Aphthae may be a manifestation of Crohn's disease in the oral cavity (can not be underestimated). Treatment is symptomatic, the changes are spontaneously healed.

c) erosions in the cervix - loss of normal vaginal epithelium of the cervix which expose mucous membrane and are visible as red spots or they are replaced by columnar epithelium of the cervical canal, which leads to an inflammation. Their formation may contribute to chemical agents (pessaries, pills, hormonal contraception), mechanical stress, hormonal changes and infections. Correct diagnosis is performed by colposcopy, microbiological and cytological examination of vaginal smear and histological slice. Treatment is symptomatic (globules) or in more severe cases - treatment (electrocoagulation, chemicals, cryocoagulation, photocoagulation).
