According to the clinical manifestations, the disease can be divided into four types: 1 and immersion type, in which the skin between toes (fingers) is whitish, erosive and immersed, with clear edges, and moist bright red newborn skin is left after removing the impregnated epidermis. 2. Blister type is more common in blisters on the soles of feet or palms, and even several blisters merge into larger blisters, with clear boundaries and red skin. 3. Scaly type is mainly desquamation, with a few blisters occasionally. Blisters are dry and desquamated, with clear boundaries and no obvious inflammation. 4. Thickening type is more common in the skin of palms and soles, blisters desquamate in summer, and skin cracks in winter. This disease is more common in adults, and often occurs or worsens in summer. When the weather is dry in winter, it is relieved or the symptoms disappear, so winter is the best time to treat tinea manus and pedis. Blister tinea manuum and pedis, the common name of tinea pedis is "foot", also called beriberi and foot moisture. Symptoms are blisters between the toes, beriberi peeling or white and soft skin, erosion or skin thickening, roughness and cracking, which can spread to the soles of feet and instep edges, causing severe itching and must be scratched. Therefore, it is often accompanied by secondary infection, resulting in local suppuration, redness, pain, swollen inguinal lymph nodes, and even erysipelas and cellulitis in the leg. Due to scratching the itchy place with your hands, it is often transmitted to your hands and tinea manus (goose palm wind) occurs; Fungi grow on the fingernails, and they become onychomycosis (onychomycosis). Fungi like moist and warm, and it is hot and sweaty in summer. Those who wear rubber shoes and nylon stockings provide a hotbed for fungi. In winter, the condition improved, showing skin cracking. This is a contagious disease, which will be quickly caused by the use of washbasins, footbaths, foot towels, hand towels, slippers and bathtubs. Tinea manus and tinea pedis are superficial fungal infections that occur in the skin between the palm, metatarsus and fingers and toes. The main pathogens are Trichophyton rubrum, Trichophyton mentagrophytes and Trichophyton floccosum. Chinese medicine calls tinea manus "goose's paw wind", and tinea pedis is also called "foot moisture". Traditional Chinese medicine thinks that this disease is mostly caused by damp-heat of spleen and stomach ascending along the meridian, which leads to tinea pedis, or by damp-heat generating insects or epidemic diseases.
