Athlete's foot (tinea pedis) is a fungal infection affecting the feet and tinea corporis is a fungal infection affecting the body and limbs.
Tinea or fungal infections often present with rashes that are ring-shaped and scaly. The rash is usually itchy. Less commonly, the area may have small blisters or tiny pustules.
Areas which are more prone to sweat and moisture like the feet and groin areas are more commonly affected and fungal infections are more prone in individuals who perspire a lot.
Sometimes, feet eczema can also present with itchy and scaly rashes. Fungal infections and feet eczema can also co-exist. A fungal scrape, where the skin scraping is sent for microscopic examination, can be ordered to confirm the diagnosis of a fungal infection if there is any doubt.
