Rashes that look like ringworm

Ringworm, also called tinea corporis, is a fungal infection that can form an expanding scaly edge with clearer skin toward the centre. Eczema, psoriasis, contact irritation, and other rashes can also look circular or scaly. Itching, scaling, a raised border, exposure to an infected person or animal, and lesions in several body areas can help a clinician assess the pattern, but they do not prove the cause. Read more about [Skin Rash](/symptoms/skin-rash/) and [Scaly Skin](/symptoms/skin-scaling/).

Keep the area clean and dry, wash hands after touching it, and avoid scratching. Do not share towels, clothing, bedding, hairbrushes, or sports equipment until the cause is clear. Wash clothing and towels regularly and avoid applying steroid cream alone to a rash that could be fungal, because it may change the appearance and allow infection to extend. A clinician or pharmacist can advise whether [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) is suitable.

Arrange an examination if the rash is enlarging, recurrent, widespread, painful, draining, or not improving with appropriate care. Seek prompt medical advice when it affects the scalp, nails, face, or a person with reduced immunity, because treatment choices may differ. Urgent help is appropriate for fever with rapidly worsening redness, severe pain, or swelling around the eye. A clinician may consider [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/) when topical care is unsuitable or the area involved needs a different approach.

Ask whether the border and scale fit a fungal infection, whether a skin sample is useful, how to protect household members, and when improvement should be expected. Mention contact with pets, shared facilities, new products, and any previous creams used.
