Red patches on the skin, if accompanied by intense itching, may have more causes, possibly allergic dermatitis due to allergic factors. Small papules may appear on the skin, and there may be eczema-like dermatitis, or even vesicular oozing. Tinea corporis may also be caused by a fungal infection. Tinea corporis manifests clinically as patches with particularly clear borders, a heavy inflammatory reaction around them, and a tendency to heal in the center. It is recommended that you can choose to go to your local hospital to test the dander for the presence of this fungal component, and if it is fungal negative, the treatment is similar whether it is atopic dermatitis or eczema-like dermatitis. You can take oral loratadine tablets and use topical hydrocortisone butyrate cream, etc. In the case of tinea corporis, antifungal treatment is required with topical antifungal medications such as naftifine ketoconazole cream, etc.
