The boundary of the damage is unclear. When combined with infection, pustules, purulent exudate and scabs may appear. 2, subacute eczema: often due to improper treatment of damage in the acute phase, the lesions to red papules, maculopapular rash, scales or crusts, but also a few papules or blisters and vesicles exudate. 3, chronic eczema: more acute, subacute eczema repeatedly does not heal transformed, the lesions are dark red or brown-red spots or macules, often fused thickening moss-like changes, the surface has scales, scratches and scabs, scattered around a few papules, macules, etc..

In the subacute and chronic stages, the epidermis is thickened, with hyperkeratosis, hyperkeratosis, and mild spongiform edema. The epidermal protrusion is significantly prolonged in the chronic phase.
