TINEA CORPORIS

By Gary M. White, MD

Tinea Corporis


Tinea corporis (aka ringworm) is a fungal infection of the skin, usually on the trunk or extremities, by a dermatophyte.

Clinical

A red, annular scaly lesion or lesions is seen. The border is often said to be "active", meaning it is more red, inflammatory, raised, etc. Larger plaques or areas may occur, emanating from the gluteal cleft, web spaces or occurring anywhere. At times, the body's immune response is so exuberant that only an inflammatory plaque is seen (see tinea, inflammatory).

Differential Diagnosis

See annular, red, scaly lesions.

Treatment

For limited disease, a topical antifungal medication is indicated. For more widespread disease, an oral antifungal (e.g., terbinafine) should be given. Patients who get tinea corporis often have recurrences. In order to minimize these, any tinea infection of the nails should be eliminated (see onychomycosis) and tinea of the feet suppressed (see tinea pedis).

Oral ketoconazole should not be used due to the risk of fulminant hepatitis.

Additional Pictures

The dorsal hand and wrist rash is less obvious. The ventral wrist has the characteristic active edge.
