|Description:||This photograph reveals dermatopathologic changes of the scalp due to what was diagnosed as ringworm, which had been caused by the dermatophyte, Trichophyton tonsurans. In this particular case, the scalp lesions had become suppurative, i.e., infected.|
What are dermatophytes?
Dermatophytes are types of fungi that cause common skin, hair and nail infections. Infections caused by these fungi are also known by the names “tinea” and “ringworm.” It is important to emphasize that “ringworm” is not caused by a worm, but rather by a type of fungus called a “dermatophyte.” One example of a very common dermatophyte infection is athlete’s foot, which is also called tinea pedis. Another common dermatophyte infection affecting the groin area is jock itch, also known as tinea cruris.
