Dry eczema: The manifestations of eczema are polymorphic, which can be manifested as local dryness, flaky erythema, pinpoint-sized papules, covered with dry scales on the surface, and often accompanied by obvious itching. However, the specific situation is still to go to the ** department for the next step of diagnosis and treatment.
