Abstract

Dermatophytic fungi cause human infection worldwide. One clinical syndrome—tinea barbae, which closely resembles tinea capitis—is a trichophytosis involving the beard and mustache areas of the face. The fungal agents responsible for tinea barbae (Trichophyton verrucosum and Trichophyton mentagrophytes) are contracted through occupational exposure to animals infected with zoophilic dermatophytes. Tinea barbae may be confused with other facial infections, especially those caused by Staphylococcus aureus or other facial dermatophytes (usually anthrophilic). In an afebrile patient without leucocytosis, a distinctive facial lesion, called a kerion, can be the essential diagnostic finding. Diagnosis requires suspicion based on appropriate exposure. Definitive diagnosis requires a combination of clinical examination, direct microscopic examination using potassium hydroxide, and culture confirmation. Topical treatment is not effective. Oral therapy with an antifungal (eg, terbinafine) or an azole is recommended. This article reviews these factors, as well as germane epidemiologic and prevention measures.
