If the ringworm on the elbow is psoriasis, you can apply topical halometasone cream once in the morning and carbotriol cream once in the evening for 1-2 weeks, and after improvement, change to carbotriol cream for 5 days, once in the morning and once in the evening, and halometasone cream for 2 days, once in the morning and once in the evening. Thereafter, halometasone cream was discontinued and replaced by carboplatinum cream applied topically once in the morning and once in the evening until the lesions subsided. If the neurodermatitis is due to frictional irritation, halometasone cream alone can be used, while avoiding friction and dry skin, and can be combined with 10% urea cream ointment. If ringworm is due to fungal infection, you can use topical antifungal medications, such as lilapamide cream, bifenazole cream, terbinafine cream, etc.
