Lichen Planus is a disease of as yet incompletely elucidated etiology; it generally affects adults and consists of a papular squamous tegumentary rash with predominantly isolated elements, accompanied by pruritus and by possible lesions of the mucous membranes (buccal and/or genital); it generally resolves spontaneously, except for the hypertrophic lichen planus that chronically persists for an undetermined period of time.
The disease is relatively frequent in adults with mentally straining professions (daily stress).
It may be associated to chronic hepatitis C or with the asymptomatic hepatitis C carrier status.
The severe itching may cause insomnia, neurasthenia and situational neurosis with the alteration of the quality of life.
