Lichen Planus is an inflammatory condition of the skin and mucous membranes that affects many people. It commonly appears as small bumps or a rash over certain areas of the body including the scalp, genitals, and the inside of the mouth. It is also known for affecting the appearance of fingernails and toenails in some cases.
What are the symptoms?
Depending on what part of the skin, lichen planus often causes bumps that are shiny, firm, and reddish purple in color. The bumps may have tiny white lines running through them that are called Wickham’s striae. The quantity of bumps can range from few to many. Common places for bumps to appear include the wrists, lower back and ankles. Other uncommon places the bumps may appear include anywhere else on the skin, including the genitals.
Who gets it?
Lichen planus is most common in middle-aged adults; however, a person of any age can get lichen planus.
Often, dermatologists can tell whether you have lichen planus by examining your skin, nails and mouth, however, they may need to remove a little skin and examine it under the microscope. Once lichen planus is diagnosed, treatment options may include:
Topical (applied to the skin) corticosteroid
Tacrolimus ointment or pimecrolimus cream
