Tinea corporis

Alternative names:

fungal infection of the body; fungal skin infection; infection - fungal (body); tinea circinata; tinea of the body

Definition:

An infection of the body surface with mold-like fungi called dermatophytes.

Causes, incidence, and risk factors:

The body normally hosts a variety of microorganisms, including bacteria, mold-like fungi (dermatophytes) and yeast-like fungi (such as Candida). Some of these are useful to the body. Others may multiply rapidly and form infections. Fungal infections are caused by microscopic plants (fungi) that can live on the dead cells of the hair, nails, and outer skin layers.

Tinea corporis (often called ringworm of the body) is a common skin disorder, especially among children, but may occur in people of all ages. It is caused by mold-like fungi (dermatophytes). See also tinea capitis (involving the scalp), tinea cruris (jock itch), and tinea pedis (athlete's foot).

Candida (yeast) infections that involve the skin include diaper rash, oral thrush, cutaneous candidiasis, and similar disorders.

Fungi thrive in warm, moist areas. Susceptibility to fungal infection is increased by poor hygiene, prolonged moist skin, and minor skin or nail injuries.

Tinea infections are contagious and can be passed from direct contact or contact with items such as combs, clothing, shower or pool surfaces. They also can be transmitted from contact with pets that carry the fungus (cats are common carriers).
