RINGWORM
What is Ringworm?
Ringworm is an infection of the body surface with mold-like fungi called dermatophytes.
It is caused by mold-like fungi
(dermatophytes). Ringworm can affect skin on your body (tinea
corporis), scalp (tinea capitis), groin area (tinea cruris, also called
jock itch), and feet (tinea pedis, also called athlete’s foot).
What are the Symptoms of Ringworm?
- itching of the affected area
- skin lesion, rash
- usually on exposed body areas
- ring shaped
- reddened patch (skin, abnormally dark or light)
- borders advance and spread, and the center clears
- borders appear scaly and distinct
How is Ringworm Diagnosed?
The diagnosis is primarily based on the appearance of the skin.
Certain species of fungus will appear florescent if the skin
is examined with a special blue light, called a Wood's lamp,
in a dark room. A more definitive diagnosis can be made by scraping
the affected area of skin and examining the cells under a microscope.
The fungi have a characteristic "spaghetti and meatballs"
appearance. The skin scrapings can also be sent to the microbiology
laboratory, and the fungus will grow in the culture medium.
What is the Treatment for Ringworm?
Ringworm usually responds to self-care. Keep the skin clean and dry. Over-the-counter antifungal or drying powders, lotions, or creams are applied to the affected skin. Those that contain miconazole, clotrimazole, or similar ingredients are often effective in controlling ringworm.
Severe or persistent infection may require further treatment by the health care provider. Oral antifungal medications may be given, and are necessary if the hair is involved. Stronger, prescription topical antifungal medications, such as ketoconazole or sulconazole may be needed. In some cases, topical corticosteroids may be added to the topical antifungals. Antibiotics may be needed to treat secondary bacterial infections.
