Ringworm is a common skin disorder, especially among children, but it may affect people of all ages. Although its name suggests otherwise, it is caused by a fungus, not a worm. Also called tinea corporis, ringworm of the body is closely related to other skin conditions with similar names. Tinea is a type of fungus, and corporis is the Latin word for "body." Ringworm can affect skin on your body (tinea corporis), arms, legs, trunk and face. Often, there are several patches of ringworm on your skin at once.
· Athlete's foot (tinea pedis) - This form affects the moist areas between your toes and sometimes on your foot itself.
· Jock itch (tinea cruris) - This form affects your genitals, inner thighs and buttocks.
· Ringworm of the scalp (tinea capitis) - This form is most common in children and involves red, itchy patches on the scalp, leaving bald patches.
Black Dot Tinea Capitis - Is a very rare form of ringworm of the scalp. Although it is not considered to be very serious, the disease is responsible for causing few noticeable symptoms, thus being more difficult to detect during medical examinations. This form of ringworm of the scalp causes the occurrence of tiny black spots which are sometimes spread over the entire surface of the scalp. The infection causes no inflammation or redness, and it rarely involves deterioration of the hair or scarring. This type of ringworm of the scalp is considered to be contagious and thus temporary isolation may be recommended to all affected patients. However, the disorder can be easily overcome with local treatments consisting of specific antifungal agents.
· Itchy, red circle of rash with healthy looking skin in the middle
· Itchy, red, raised, scaly patches that may blister and ooze
· The patches often have sharply-defined edges.
