Lichen planus is a itchy skin rash. The cause of lichen planus is unknown. It consists of small, shiny, purple spots that occur suddenly and disappear gradually for several weeks or months, leaving a smooth brown spot. If the lichen planus appears in the mouth (in that case, we call it oral lichen planus), a white lace-like patch appears on the mucous membrane. Lichen planus can appear on the nails of the toes on hands and feet. If it appears on the scalp, it can cause hair loss.
Lichen planus is rare; it occurs mainly in middle-aged people. Although it is harmless, you should always contact your doctor in case of doubt.
Most doctors can diagnose the lichen planus with the naked eye. The doctor will probably prescribe corticosteroid fat to reduce irritation and rash.
Corticosteroid fat usually works in severe cases, so they are treated with corticosteroid tablets for two or three weeks, although the condition is known to come back after cessation of therapy.
The cause of this skin rash is unknown, though some doctors believe it is a virus. The rash appears in the form of a red dots, or a few, generally on the torso. During the next few days the number of dots increases, and they are spread over the torso, upper arms and thighs. The dots ”evolve” into oval patches of red or copper colored blotchy edges. The spots can itch. The disorder mostly affects children and young adults. Pitvriasis rosea is completely harmless, but you have to go to the doctor and check that it may not be some other, similar skin disorder.
Your doctor may advise you to wait for the rash to disappear on its own – which often occurs after a few weeks or months. If your rash is not excessively itchy, you can also help yourself with liquid powder. If the rash is very strong, your doctor may prescribe the corticosteroid cream, while severe itching may be relieved with antihistamine tablets.
