Tinea capitis is a fungal infection of the scalp that is contagious and often itchy. Tinea capitis usually appears only on the patient’s scalp, but in severe cases it can even spread to areas such as behind the ears or to the chest. The symptoms of neurodermatitis are mainly due to paroxysmal itching of the patient’s skin, and even papules of varying sizes of green beans may appear on the skin. As the patient scratches, the number of papules will gradually increase and can flare up all over the body. It is recommended that once patients have obvious skin discomfort, they must go to a regular hospital for treatment to avoid aggravating the condition and causing unnecessary effects on the recovery of the disease.
