Tinea versicolor is a superficial fungal infection caused by a fungus that invades the epidermis of the palm. How do you get ringworm? The causative organisms are mainly Trichophyton and Epidermolysis bullosa, and the common strains are red Trichophyton, Trichophyton and flocculent Epidermolysis bullosa, among which red Trichophyton has become the main causative organisms of tinea cruris in our country because of its strong resistance and not easy to control. This disease is transmitted through contact. Symptoms of tinea versicolor: the clinical manifestations of tinea versicolor are roughly the same as tinea pedis, but the typing is not as obvious as that of tinea pedis. At the beginning of the damage, there are often scattered small blisters, and then often with the main flaking, the skin lines deepen, touch the rough, the disease for a long time to present keratinization thickening. A certain boundary is often seen between the affected area and normal skin. The damage is mostly limited to one side, and at the beginning, it often starts at the palm, the second, third or fourth finger palm, and in the long run, it involves the whole palm of the hand. Self-awareness of symptoms is not obvious tinea versicolor is similar to tinea pedis, but mainly scaly keratinized type, occasionally blister type lesions, and interphalangeal vesicles are rarely seen (except for candida interphalangeal vesicles). Tinea cruris is often secondary to tinea pedis, and most often starts with one hand, and if left untreated can develop into both hands after a number of years. Since the hands are used for work, ringworm often causes new infections such as tinea corporis and tinea cruris.
