All of the conditions listed above are caused by a fungal infection and are referred to as “tinea.” Athlete's foot is a fungal infection that usually begins between the toes. It commonly occurs in people whose feet become very sweaty while wearing damp socks and/or tight-fitting shoes. Jock itch or “tinea cruris” is the same thing but occurs in the groin and ringworm is called “tinea corporis” and can occur anywhere on the body. Tinea capitis is a fungal infection on the scalp.



Tinea is a pink or red skin rash that can form a scaly patch or ring shape around normal skin. It can itch, sting or burn. When it appears on the scalp it can even cause areas of hair loss. It is contagious to others and can also spread to other areas of your body.


Tinea is often diagnosed from its clinical appearance but sometimes your dermatologist will need to take a skin scraping to look under the microscope for evidence of fungal hyphae or to send to a laboratory to identify the fungus by staining a biopsy or by growing it in a culture.
