How to determine whether it is dermatitis or moss

The difference between dermatitis and ringworm lies in the etiology and symptoms. Dermatitis is caused by allergic reasons. Patients in the acute stage often show long erythema, wheals, and may also be accompanied by pimples, blisters, and erosions. With the continuous development of the disease, when in the chronic stage of the disease, the skin will show roughness, hypertrophy, accompanied by pigmentation or hypopigmentation. When the patient's body grows ringworm, it will show a relatively mild inflammatory reaction, showing erythema and desquamation. Some patients may feel mild itching, often high in summer and lighter in winter.
