Athlete's foot, medically known as tinea pedis, is a fungal infection. If someone with tinea pedis scratches their feet with their hands, they can transfer the fungus to their hands, resulting in tinea manuum, which is characterized by peeling skin on the hands. However, there are two common conditions that lead to hand peeling. One is tinea manuum, a fungal infection of the hands, often spread from tinea pedis. The other condition is eczema, so it is necessary to differentiate whether the symptoms are due to tinea manuum or eczema. Patients with tinea manuum typically have the infection on two feet and one hand; usually, only one hand is affected initially, not both hands symmetrically. If it is difficult to differentiate, it is advisable for patients to undergo a fungal examination at a hospital, which can confirm the diagnosis if the result is positive for fungus.
