What is the medical term for a fungal infection of the feet?

The medical term for a fungal infection of the feet is indeed "Tinea pedis." This condition is also commonly referred to as athlete's foot and is characterized by itching, scaling, and redness on the skin of the feet, typically between the toes. Tinea pedis is caused by various types of fungi that thrive in warm, moist environments, making the feet an ideal location for infection, particularly when wearing tight shoes or in areas like swimming pools.

While "Onychomycosis" refers to a fungal infection of the nails, and "Tinea corporis" pertains to fungal infections of the body, "Dermatophyte" describes a type of fungus responsible for various skin infections, including tinea. Therefore, these terms relate to different conditions, whereas "Tinea pedis" specifically targets the foot area, making it the correct choice for this question.
