The so-called contact eczema should refer to contact dermatitis, which is a clinical manifestation of erythema, papules, papules, blisters, and significant itching due to accidental contact with some objects that are strongly irritating to them. For this condition, the patient needs to apply anti-allergy drugs, which are commonly used clinically, such as glucocorticoids and antihistamines. Patients with apparently no exudation can choose to apply topical application of stove glycolic lotion with glucocorticoid ointment. If patients have obvious exudation, they can apply boric acid solution and other wet compresses, and then apply glucocorticoids for topical treatment when there is little exudation. It is important to note that patients with contact dermatitis are prone to secondary skin infections.
