Lichen diseases - Definition

Definition


The lichens are skin diseases belonging to the group of dermatoses which may also affect the mucous membranes, body tissue covering the inside of organs. There are several types of lichens, the most common being the "lichen planus" and "lichen sclerosus." The causes of these two diseases - such as those of several other lichens - are not yet known with certainty. Most often, a lichen is manifested by the appearance of small, elevated lesions on the skin called papules, as well as a certain degree of skin thickening. Itching may also occur. Treatment depends on the type of lichen.
