This picture shows a skin inflammation of the fingers with multiple blisters (vesicles) caused by an allergic reaction to a fungal infection (tinea corporis). (Image courtesy of the Centers for Disease Control and Prevention.)

This child's leg shows a classical-appearing ringworm lesion with central clearing and a slightly raised red border.

In the scalp, fungal infections often form circular, scaly, inflamed patches. Frequently, there can be temporary hair loss (hair returns when infection clears but if treatment is delayed and scarring results, permanent hair loss can be seen). This is a classical example of ringworm (tinea capitis) in a young child.

This is a picture of ringworm (tinea) on the hand and leg. Tinea is a fungal infection of the skin. Ringworm is not seen as frequently in adults as in children, but when conditions are conducive to growth, the fungus can flourish.

This is a picture of ringworm, tinea manum, on the finger. This fungal infection is inflamed and scaly.

Ringworm is a fungal infection of the skin. It usually produces a ring-shaped lesion which appears to clear in the center. The edges of the lesion may be slightly raised and often itch. Central clearing can be seen in some of the infected areas on the leg of this person.

Ringworm is a common skin disorder, especially among children, but may occur in people of all ages. It is caused by mold-like fungi (dermatophytes).
