Overview

Background

Tinea faciei is a superficial dermatophyte infection limited to the glabrous skin of the face. [1] In pediatric and female patients, the infection may appear on any surface of the face, including the upper lip and chin. In men, the condition is known as tinea barbae when a dermatophyte infection of bearded areas occurs.

Pathophysiology

Keratinophilic fungi, or dermatophytes, are responsible tinea faciei. Dermatophytes release several enzymes, including keratinases, which allow them to invade the stratum corneum of the epidermis. Infection caused by zoophilic dermatophytes is usually associated with inflammatory reactions that are more severe than those due to anthropophilic fungi.

The zoophilic dermatophyte Trichophyton species of Arthroderma benhamiae, most commonly from pet guinea pigs, is linked with an inflammatory tinea faciei in children and adolescents, particularly in Germany. [2]

Epidemiology

Frequency

Tinea faciei is not an uncommon disease. It occurs worldwide. However, as with other cutaneous fungal infections, it is more common in tropical regions with high temperatures and humidity. [3, 4, 5, 6] Tinea faciei was shown to represent approximately 19% of all superficial fungal infections in the pediatric population with dermatomycoses. [7]

Sex

Some authors suggest that females may be affected more frequently than males, but the difference is probably semantic. In females, dermatophyte infection of the face is more likely to be diagnosed as tinea faciei, whereas many infections that occur in similar locations in men are diagnosed as tinea barbae. Data indicate a female-to-male ratio of 1.06:1. [8]

Age

Tinea faciei may appear in persons of any age, with two peaks of disease incidence. It has been described in a 14-day-old girl. [9] One peak involves children, who constitute a large group of patients because of their frequent direct contact with pets. Tinea faciei is commonly noted as a dermatosis that occurs after holidays; it is diagnosed more frequently in children after they spend their holidays in rural areas, where they may come into contact with animals when they play. Several cases are also reported in neonates [10, 11, 12] ; these patients may acquire the infection from siblings or contact with pets. The other peak occurs in those aged 20-40 years.

Prognosis

The prognosis for patients with tinea faciei is usually good. The lesions respond to topical and oral antifungal treatment within 4-6 weeks. Scarring may occur in patients with Trichophyton schoenleinii infection; this is extremely rare.
