Sialadenitis includes a number of infections of the salivary glands with different etiology. Both large salivary glands responsible for production of saliva like parotid, submandibular, sublingual as well as small salivary glands, which are located on the lips, palate, tongue and cheeks, can be affected by inflammatory conditions. Virus and bacterial infections and autoimmunological disorders can be the causative factors, and the presentation may be acute, chronic or chronic exacerbated. Lichen sclerosus (LS) occurs very rarely at the oral mucosal sites. LS is the most commonly affects the anogenital region, but it can also involve any area of the skin. Here, we present the case of a 64‑year‑old patient with chronic exacerbated inflammation of small salivary glands in the course of lichen sclerosus.

Key words: chronic sialadenitis, lichen sclerosus.
