Tinea faciei is a superficial fungal infection of the skin of the non-bearded part of the face.[6] It generally appears as a photosensitive, painless, red rash with small bumps and a raised edge appearing to grow outwards, usually over eyebrows or one side of the face.[2] It may feel wet or have some crusting, and overlying hairs may fall out easily.[3] There may be a mild itch or burning sensation.[6]

Tinea faciei can be caused by spread of fungal infections of the feet and nails, from pets such as cats and dogs, and from farm animals.[1] Causative organisms include T. rubrum, T. mentagrophytes, T. tonsurans, M. gypseum and M.canis.[5] Often misdiagnosed as an inflammatory condition, for which corticosteroids are applied, tinea faciei may be complicated by tinea incognita.[4]

Diagnosis is by the appearance of the rash and confirmed by taking a skin scraping for microscopy and culture,[3] or biopsy.[2] Differential diagnoses include lupus erythematosus, impetigo, eczema, herpes zoster,[4] seborrhoeic dermatitis, psoriasis, rosacea, actinic keratoses, perioral dermatitis and polymorphous light eruption.[1] Treatment is with topical antifungal medication; terbinafine, clotrimazole, miconazole and ketoconazole.[3] If the condition does not respond to topical treatment or is extensive, then oral terbinafine or itraconazole can be taken.[1]

The condition is uncommon.[1]

Signs and symptoms

It generally appears as a photosensitive painless red rash on the face, followed by patches of small, raised bumps.[2] It is considered distinct from fungal infection of the beard area.[3] The rash may weep or crust, and hairs may fall out easily. It is usually painless.[3]

Causes

It is usually caused by T. rubrum, T. mentagrophytes, M. gypseum, T. tonsurans.[5]

Diagnosis

Diagnosis is by the appearance of the rash and confirmed by taking a skin scraping for microscopy.[3]

Treatment

A & B. Tinea faciei before treatment C. 1 month of antifungal and anti-inflammatory treatment.

Treatment is usually with topical antifungal medication such as terbinafine cream twice daily for 2 weeks, or miconazole twice daily for 2-4 weeks.[3][2] Extensive infection may require treatment with oral terbinafine for 2 weeks.[3]
