Spectrum Of Disease

Cutaneous mycoses are perhaps the most common fungal infections of humans and are usually referred to as tinea (Latin for "worm" or "ringworm"). The gross appearance of the lesion is that of an outer ring of the active, progressing infection, with central healing within the ring. These infections may be characterized by another Latin noun to designate the area of the body involved. Examples include Tinea corporis, which is ringworm of the body; Tinea cruris, which is ringworm of the groin (i.e., "jock itch"); Tinea capitis, which is ringworm of the scalp and hair; Tinea barbae which is ringworm of the beard; and Tinea unguium, which is ringworm of the nail.


Members of the genus Trichophyton are widely distributed and are the most important and common causes of infections of the feet and nails; they may be responsible for tinea corporis, tinea capitis, tinea unguium, and tinea barbae. They are most commonly seen in adult infections, which vary in their clinical manifestations. Most cosmopolitan species are anthropophilic, or "human-loving"; few are zoophilic, primarily infecting animals.

Generally, hairs infected with members of the genus Trichophyton do not fluoresce under the ultraviolet (UV) light of a Wood's lamp; the demonstration of fungal elements inside, surrounding, and penetrating the hair shaft, or within a skin scraping, is necessary to diagnose a dermatophyte infection by direct examination. The recovery and identification of the causative organism are necessary for confirmation.
