Eczema in adults is characterized by a symmetrical, indistinct rash that can occur anywhere around the body, such as the face, neck, ears, trunk, extremities, and hands and feet, with erythema, macules, papules, blisters, papules, plaques, scales, scratches, crusting, vesicles, and oozing, accompanied by itching as a conscious symptom. Some of the adjacent rashes may fuse with each other to form patches, and there is some occurrence of pain due to ulceration and erosion. On the basis of this symptom, the rash may also show capillary dilation, aggravated by heat and relieved by cold, which requires anti-allergy treatment in clinical treatment.
