Tinea corporis is a fungal infection of the smooth skin between the fingers, palms, and palms, caused by Trichophyton rubrum, Trichophyton spp., Microsporum gummi, and Trichophyton flocculare. This type of ringworm is characterized by multiple blisters, collar-like flaking, and pronounced itching. Hyperkeratotic tinea cruris occurs on the palm surface skin and thick keratinous areas on the flexor side of the palm. The lesions are dry and flaky with obvious focal keratinous thickening, and there is usually no obvious itching, but the excessive keratinous thickening in the autumn and winter months can easily lead to a decrease in epidermal elasticity of the lesions, which can easily lead to bleeding and pain. It is appropriate to use topical ointments containing urea and glycerin along with azole and acrylamide antifungal creams to soften and remove the overly thickened keratin, promote the absorption of antifungal medications, and relieve the symptoms of dryness and chapping. Patients with tinea capitis, which occurs in the fingertip area, tend to have sweaty hands and long-term water immersion as triggers. While using topical antifungal creams, care needs to be taken to keep the hands dry, pay attention to labor protection, and reduce the damage caused by acidic and alkaline substances to the skin on the hands in order to restore the integrity of the keratin layer in the local lesion area as soon as possible. In addition, since tinea capitis is mostly caused by secondary infection after scratching of tinea pedis, patients with tinea capitis and tinea pedis need to treat both hands and feet together and avoid cross-infection during the treatment process; as for the course of treatment, due to the thick keratinous nature of tinea capitis, treatment needs to be continued for 1-2 months to obtain satisfactory results and avoid repeated fungal infections.
