Tinea refers to a group of infections caused by fungus. Tinea is also known as "ringworm"..even though it has nothing to do with worms. The ringworm infection is often a well demarcated ring on the face, scalp or body.
The culture of this lesion showed Trichophyton rubrum, a common fungal species that also causes nail infection (onchomycosis) and athletes foot. The skin infections are easily cured with 14 days of topical treatment. Nail infections are difficult to cure.
The fungal infection "athletes foot" is also called Tinea pedis. Topical treatment usually cures it.
