Lichen sclerosus is a rare skin condition that usually affects the skin of the genital & perianal regions of the body. This disorder can also progress to the epidermis of the torso, upper arms or even breasts, it can involve any part of the body, though it’s rare. It is a long-standing skin disorder characterized by the appearance of trivial whitish patches that are typically thinner than usual.       

Lichen sclerosus does not spread over contact, i.e., not transmissible. Correspondingly it is not a sexually transmitted disease, thus it cannot spread by the sexual intercourse too.

The resources of lichen sclerosus are somewhat still unidentified as the understanding of the disorder is inadequate. Though, researches are still ongoing to precisely identify the origin(s), and to find a long-lasting solution, as presently there is no cure for this. At this instant, doctors think it might be genetic, hormonal, as a result of infection or it may be a combination of all the things. One more theory proposes that it might be an autoimmune disease. An auto-immune syndrome occurs when your immune system tags your normal body tissues as external tissues and starts to attack them, in guard.
