Clinical Terms for Dermatophytosis (B35)

Dermatophytosis-. Fungal infection of keratinized tissues such as hair, skin and nails. The main causative fungi include MICROSPORUM; TRICHOPHYTON; and EPIDERMOPHYTON. Other names used: Tinea.

Tinea Pedis-. Dermatological pruritic lesion in the feet, caused by Trichophyton rubrum, T. mentagrophytes, or Epidermophyton floccosum.

Tinea Capitis-. Ringworm of the scalp and associated hair mainly caused by species of MICROSPORUM; TRICHOPHYTON; and EPIDERMOPHYTON, which may occasionally involve the eyebrows and eyelashes.

Tinea Favosa-. A disease of the scalp that may affect the glabrous skin and the nails and is recognized by the concave sulfur-yellow crusts that form around loose, wiry hairs. Atrophy ensues, leaving a smooth, glossy, thin, paper-white patch. This type of disease is rare in the United States and more frequently seen in the Middle East, Africa, Southeastern Europe, and other countries bordering the Mediterranean Sea.
