|Description:||This image depicts a close view of the skin surface of a patient who’d presented with a case of what was diagnosed as tinea corporis, a fungal infection involving the skin, and in this instance, was caused by the dermatophytic fungal organism, Trichophyton tonsurans. Note the shiny, dry plaque on the skin’s surface, which was roughened about its perimeter, but smoothed out in response to pressure applied by the tip of a sharpened metal probe.|
Dermatophytes are fungi that cause skin, hair, and nail infections. Infections caused by these fungi are also sometimes known as "ringworm" or "tinea." Despite the name "ringworm," this infection is not caused by a worm, but by a type of fungus. There are many types of infections caused by this fungus. The infections are generally identified by its location on the body, as an example, tinea capitis, is a ringworm infection involving the scalp.
