Is ringworm rash ringworm or allergy? Overview: Ringworm rash is an allergic condition in which a fungus causes an inflammatory infection at the site of ringworm that produces an allergen (ringworm toxin), resulting in a rash of many forms of skin around or away from the ringworm. Ringworm rash is most often seen in the summer and fall and often occurs during the acute inflammatory phase of various ringworm diseases. The disease is easily triggered by ringworm co-infection or by strong irritation from medications used to treat ringworm. Common types of ringworm rash: 1. Acute disseminated ringworm rash: Often presents with follicular, mossy or scaly lesions mainly on the trunk, pinhead-sized sharp or flat moss-like papules. They often form ring-shaped scaly patches. Some cases are associated with generalized lymph node enlargement, splenomegaly, and leukocytosis. This type is more common in patients with tinea capitis. 2. Herpetic type: It is often symmetrically distributed on the palms of the hands with the lateral margins of the fingers, and the lesions are mostly blisters with severe itching. It is mostly seen in patients with tinea pedis. 3. Erythema and dermatophytosis-like type. The skin often shows erythema annulare, tinea cruris and urticaria-like ringworm rash on the lower extremities. Mostly seen in patients with tinea pedis. Treatment and prevention: 1. Treatment: The treatment of ringworm rash is divided into two steps. Symptomatic treatment of anti-allergy is the first step, usually using antihistamines, commonly loratadine, benzosuberastine and so on. If the symptoms are more severe they can be treated systematically with glucocorticoids. Waiting for the symptoms of ringworm rash to subside and the infected area to control inflammation to subside further treats ringworm with antifungal medications. Topical medications are chosen for symptomatic treatment, and commonly used medications include compounded preparations such as glycopyrrolate lotion, boric acid solution, and application of trimethoprim ointment. After the ringworm rash is controlled and stabilized, treatment of ringworm is the second step. Oral medications can be used as antifungal treatment with itraconazole or terbinafine hydrochloride tablets, and in terms of topical medications, mild antifungal creams are usually chosen as the main choice, and irritating ringworm drops are not recommended. 2. Prevention: The prevention of ringworm rash is mainly based on the rational use of medication. Because ringworm rash is mostly caused by bad irritation or infection of ringworm, it is important that the hospital professional doctor treats the ringworm rash primarily and does not believe in recipes, especially not using strong irritating tincture drugs or exfoliating drugs for rubbing and soaking.
