Lichen Planus (LP) is non-contagious, non-infectious, inflammatory skin disorder involving the skin and mucous membranes. It rarely affects the hair and nails. The symptoms include shiny, flat-topped bumps that are purple or reddish-purple and can itch. They may be seen anywhere on the body but seem to favor the inside of the wrists and ankles. The cause is unknown however medications treating high blood pressure, heart disease and arthritis can cause lichen planus-type rashes and it is rarely associated with hepatitis. The reaction goes away when the medication is discontinued and generally most cases of LP go away within 1-2 years. Unfortunately, Lichen Planus can resolve with significant discoloration depending on the patient’s skin type.
While there is no cure for Lichen Planus, there are effective treatments to manage the care of the infected skin such as antihistamines, corticosteroid or a cream to relieve the symptoms. Severe cases may require internal cortisone or specific form of ultraviolet light treatment.
