Knowra Tinea corporis Tinea corporis Tinea corporis is a superficial dermatophyte infection of glabrous skin, commonly producing an enlarging, scaly ring with a more active edge and central clearing.
Dermatophyte : A fungus that uses keratin and can infect skin, hair, or nails. These fungi cause tinea corporis by growing in the outer skin layer.
Tinea : A group of superficial infections caused by dermatophyte fungi. Tinea corporis is the form affecting body skin outside the scalp, feet, groin, and nails.
Skin scraping : A sample of superficial skin scale collected for microscopic examination or fungal culture. Scraping the active edge provides material for testing suspected tinea corporis.
Tinea corporis gladiatorum : Tinea corporis transmitted through close skin contact in wrestling and other contact sports. This named presentation often spreads through direct contact among athletes.
Nummular dermatitis : An inflammatory skin condition that causes coin-shaped, itchy patches of eczema. Its round plaques can resemble tinea corporis but lack a fungal cause.
Keratin : A structural protein abundant in the outer skin, hair, and nails. Dermatophytes feed on keratin in the stratum corneum.
Trichophyton : A genus of dermatophyte fungi that infects skin, hair, and nails. Species in this genus are frequent causes of tinea corporis.
Fungal culture : A laboratory method that grows fungi from a clinical specimen for identification. Culture can help identify the dermatophyte when diagnosis is uncertain or infection persists.
Tinea faciei : A dermatophyte infection of the face, excluding the beard area. It is a facial form of glabrous-skin tinea with a related clinical pattern.
Granuloma annulare : A benign inflammatory skin condition producing ring-shaped bumps, usually without surface scale. Its annular shape can mimic ringworm, but the lesions are typically smooth.
