Body ringworm is a dermatophyte (fungal) infection of the face, trunk, arms, and legs.
Symptoms of tinea corporis include pink-to-red, round patches on the skin that sometimes itch.
Doctors examine the affected area and sometimes view a skin scraping under a microscope to make the diagnosis.
Treatment includes antifungal medications applied directly to the affected areas or sometimes taken by mouth.

Tinea corporis is a type of dermatophytosis. Tinea corporis is usually caused by the fungus Trichophyton or Microsporum.
Tinea corporis can develop anywhere on the skin and can spread rapidly to other parts of the body or to other people with whom there is close bodily contact.
The infection generally causes pink-to-red, round patches with raised scaly borders that tend to be clear in the center. Sometimes the rash is itchy.

Several days may pass before antifungal creams, lotions, or gels reduce symptoms. (See also table Some Antifungal Medications Applied to the Skin (Topical Medications).)
Infections that are difficult to treat and relatively widespread can occur in people infected with the fungus Trichophyton rubrum
