Tinea corporis (often called ringworm of the body) is a common skin disorder, especially among children. However, it may occur in people of all ages. It is caused by mold-like fungi called dermatophytes.

Fungi thrive in warm, moist areas. Poor hygiene, long-term wetness of the skin (such as from sweating) and minor skin and nail injuries raise your risk for a fungal infection.

Tinea corporis is contagious. You can catch the condition if you come into direct contact with someone who is infected, or if you touch contaminated items such as combs, clothing, shower floors and walls, or pool surfaces. The fungi can also be spread by pets. (Cats are common carriers).

Symptoms include itching and a ring-shaped, red-colored skin rash. The rash may occur on the arms, legs, face, or other exposed body areas. The border of the rash lesions look scaly.

The primary diagnosis is based on how the skin looks.

In some cases, the following tests may be done:

• KOH (potassium hydroxide) test
• Skin lesion biopsy
