Overview

Dermatophytes cause non-lethal infection of the superficial skin, therefore, the agents causing dermatophytosis are not life-threatening. Common genera of dermatophytes causing infections include the Epidermophyton, Microsporum and Trichophyton. The causes of dermatophytosis according to the organ system involvement include, tinea corporis which is infection of body surfaces other than the feet, groin, face, scalp hair, or beard hair; Tinea pedis which is infection of the foot; tinea cruris which is infection of the groin; tinea capitis which is infection of scalp hair; tinea unguium (dermatophyte onychomycosis) which signifies infection of the nail; tinea faecei which is infection of the face; tinea barbae which is infection of the facial hair; tinea mannum which includes infection of the hands.

Causes

Life-Threatening Causes

  • Dermatophytes cause non-lethal infection of the superficial skin, therefore, the agents causing dermatophytosis are not life-threatening.

Common Causes

The common etiologic agents of the dermatophytosis can be categorized into one of three genera:[1][2]

Causes By Organ System
