About Tinea Corporis
Tinea corporis, also known as “ringworm”, is a fungal infection of the body. History of exposure to an infected pet or dog is common, or contact with other people with tinea infection. The classic lesion is annular (hence the name “ringworm”), with an elevated, scaling border and a central clearing. Some lesions may be serpiginous rather than annular.
With what can tinea corporis be confused?
Tinea corporis can be confused with other round lesions, such as nummular eczema. It may also be confused with Pityriasis rosea, psoriasis, impetigo, erythema annulare centrificum, and granulmoa annulare.
How is tinea corporis diagnosed and treated?
Fungal infections of the body are often diagnosed visually, and a provisional diagnosis made based on the typical appearance. To confirm the diagnosis a culture can be performed on a skin swab. However, it takes up to 30 days to get a result. A skin biopsy can provide an answer sooner.
Treatment of tinea corporis is usually a topical antifungal medication, such as ketoconazole. In areas with hair, oral mediciations, such as terbinafine (Lamisil) may be needed.
