The acute phase has an exudative tendency, while the chronic phase has infiltration and hypertrophy. Some patients directly present with chronic eczema. The skin lesions of eczema are generally polymorphic, mainly composed of erythema, papules, and papulovesicles. The rash is obvious in the center and gradually spreads to the surrounding areas. The boundaries are unclear, diffuse, and there is a tendency to exudate. Chronic cases will show infiltration and hypertrophy.
