Also known as onychomycosis and tinea unguium, nail fungal infections are the most common diseases of the nails, making up about 50% of nail abnormalities. Both fingernails and toenails are susceptible to the infection, which usually manifests as discoloration and thickening of the nail and crumbling edges. The condition most commonly occurs in toenails.
