What is lichen planus

First, lichen planus, the name of Chinese medicine is "purpura wind", which is not unusual in clinic. Incidence rate has increased in recent years. It is often misdiagnosed because of the variety of skin lesions. Traditional Chinese medicine believes that the disease is caused by the deficiency of Yin blood in the body, the deficiency of spleen, the deficiency of accumulation, the re sensation of wind evil, the rheumatism in the skin, the stagnation in the blood, or the deficiency of liver and kidney, the deficiency of yin and internal heat, and the deficiency of fire in the mouth. It's a disease that teenagers and adults are prone to.

Then on the skin and mucous membrane, a few cases may invade fingers, toenails and hair. The most typical lesions are flat papules slightly higher than the skin surface, small grains of rice to the size of mung bean, which are polygonal or round with clear boundary. The color is purplish red or purplish blue, dark red, reddish brown and dirty gray. The papules of the same patient are often the same size, dense distribution, some scattered distribution, some mutual fusion into different sizes, different shapes of plaque. And many people will also have itching unbearable feeling.

Finally, the lesions of lichen planus can occur in any part. But generally speaking, the number of four branches is more than that of trunk, and the number of flexed limbs is more than that of extended limbs, especially the flexed wrist, ankle and medial thigh. The damage of trunk is mostly located in the waist. Facial involvement is also rare. Scalp rash can cause permanent hair loss, mostly patchy, occasionally can cause diffuse hair loss. Scalp atrophy, or scar formation, is similar to alopecia and pseudoalopecia areata caused by lupus erythematosus.
