The difference between eczema and ringworm on the scalp area lies in the following aspects: First, in terms of etiology, eczema is mostly due to allergic factors, which may be due to allergy to hair dyes, allergy to sunlight and ultraviolet radiation, etc. Tinea capitis is caused by fungal infections, which may be due to dermatophyte infections such as Microsporum canis or Trichophyton rubrum. Second, laboratory tests, fungal microscopy and culture are usually negative for eczema and positive for tinea capitis. Third, rash manifestations, eczema can appear as a polymorphic rash such as erythema, papules, papules, vesicles, and oozing, with itching. Tinea capitis can present with hair breakage, characteristic bacteriophages, etc.
