Common clinical symptoms include limited erythema, papules, hypertrophy, cracking and flaking on the hands and feet, which are often recurrent and difficult to cure. Chronic chafing eczema clinically mainly take loratadine, cetirizine and other oral antihistamine-based, serious cases need to cooperate with dexamethasone, prednisone acetate and other glucocorticoid treatment.
