Tinea pedis, commonly known as tinea pedis, is caused by a fungal infection, but from a medical perspective, tinea pedis is strictly defined in terms of the pathogen and the site of infection. First of all, from an etiological point of view, the fungal infections of the foot that can be defined as “tinea pedis” are mainly caused by fungi of the genus Trichophyton, including Trichophyton rubrum, Trichophyton rubrum, Microsporum plasteri, and Trichophyton floccosum, of which Trichophyton rubrum is the most common, accounting for more than 50%. is also a group of fungal infections, but because Candida belongs to the genus Yeast and is generally a normal parasitic bacteria on the body surface, it can only cause disease in some immunocompromised patients and is called foot candidiasis. In addition, from the point of view of the site of infection, tinea pedis refers specifically to ringworm infections involving the interdigital, plantar, heel, and lateral edges of the foot; therefore, ringworm infections occurring on the dorsal part of the foot, whether they are primary on the back of the foot or secondary to “tinea pedis” infections of the interdigital, plantar, heel, and lateral edges of the foot, should be referred to as “Tinea corporis” and does not fall under the category of tinea pedis. In summary, tinea pedis is a superficial fungal disease of the foot caused by direct or indirect contact with epidermophytes and characterized by invasion of thick keratinous areas such as the interdigital, plantar, heel, and lateral edges of the foot.
