Tinea pedis, also known as ringworm of the foot, is a fungal infection. Tinea pedis, mainly caused by infection of Trichophyton rubrum, Trichophyton mustelii, Plaster-like microsporidia, and flocculent epidermal fungi, is mainly transmitted through contact, such as scratching the affected area with hands, or sharing shoes, socks, and foot washbasins with the patient. Tinea pedis can be divided into blistering type, scaly keratinized type and macerated vesicular type. The blistering type occurs between the toes, on the metatarsals and on the lateral margins of the feet. The lesions are deep blisters of pinpoint size, which are not easy to break, and can be fused into multi-room blisters; scaly keratosis type occurs in the palm and plantar area and the heel, which is diffuse skin roughness, thickening, flaking, and dryness. The macerated vesicular type is common in the 3rd to 4th and 4th to 5th toes, which is characterized by macerated whitish skin with a soft surface that is easy to peel off, exposing a reddish vesicular surface and ooze, often accompanied by fissures. Clinical mainly through the topical drug (terbinafine ointment, miconazole cream, bifonazole cream) treatment, patients with a longer course of the disease can choose systemic drugs (itraconazole, fluconazole, terbinafine) treatment. Patients with athlete’s foot are recommended to be treated promptly, and personal appliances are used separately, and drugs need to be selected under the guidance of a doctor.
