Lichen sclerosus is an inflammatory dermatosis of unknown etiology, possibly of autoimmune origin, usually affecting the anogenital area.
[ 1 ]
Symptoms of lichen sclerosus
The first symptoms are increased skin trauma, hematoma and blister formation. Lesions usually cause moderate to severe itching. Over time, the affected skin becomes atrophic, thin, hypopigmented, cracked and flaky. There are hyperkeratotic and fibrous forms. Severe and prolonged cases of the disease lead to the formation of scars and disruption of the groin area. In women, complete damage to the labia minora and clitoris is possible, in men - phimosis of the foreskin.
Diagnosis of lichen sclerosus
The diagnosis of lichen sclerosus is usually based on the appearance of the rash, especially as the disease progresses, but a biopsy is necessary in any case if the rash is localized in the anogenital area where seals or ulcers appear, since lichen sclerosus is a prepancrosis.
Treatment of lichen sclerosus
Strong topical glucocorticoids are used in treatment (which should be used with extreme caution). Lichen sclerosus is a fairly severe disease, sexual function should be monitored, psychological assistance should be provided, and the possible development of squamous cell carcinoma should be monitored.
