The damage is poorly defined. In combination with infection, pustules, purulent exudate and scabs may appear. (2) Subacute eczema: often evolved from the recurrence of acute eczema, the lesions are mainly red papules, maculopapular rash, scaling or crusting, with a few papules or blisters and vesicular ooze. (3) chronic eczema: more acute, subacute eczema repeatedly does not heal from the transformation of lesions for dark red or brown-red spots or macules, often fused thickening moss-like changes, the surface has scales, scratches and crusts, scattered around a few papules, macules, etc..

Systemic treatment: antihistamines, traditional first-generation antihistamines mostly have a central sedative effect, such as paracetamol, cyproheptadine. The second generation antihistamines have less or no central sedation and side effects such as dry mouth, can also be used. Such as cetirizine, loratadine, can choose 1-2 of them as appropriate.
