Eczematous dermatitis is a manifestation of dermatitis, with the main clinical manifestations being millet-sized papules, vesicopustules, or vesicles on the skin, accompanied by erythema that can merge into patchy areas. Frequent scratching can lead to exudation, erosion, secondary infection, and in severe cases, the formation of pustules and crusts. Eczematous dermatitis is a type of allergic skin disease. It is usually necessary to identify the specific allergens involved. One can visit a hospital to check for allergens and then undergo treatment with antihistamines as directed by a doctor. If there is significant exudation, topical treatment can include wet dressings with lactic acid, ichthammol solution, or boric acid solution. Treatment can also be supplemented with traditional Chinese medicine and Western medicine combined, based on differential diagnosis.
