Tinea barbae is a apparent dermatophyte infection. It is one of the reasons of Folliculitis. It is less frequent than tinea capitis and normally affects only adult men. It is most common among agricultural workers, as the transmission is more frequent from animal-to-human than human-to-human. Tinea barbae is caused by the keratinophilic fungi (dermatophytes) which are accountable for most superficial fungal skin infections. Tinea barbae is usually because of infection of churlish facial hair with an ectothrix pattern (spores on the outside).
In ectothrix infections, the fungal filaments and spores (arthroconidia) guard the outside of the hair. It's highly infectious and got its name as in the past it was spread by barbers who used contaminated razors. Like barber's itch, tinea barbae causes itchy, white bumps. Tinea barbae also grow in the beard area in men. It may also develop as an inflammatory kerion which can result in scarring hair loss. Most infections are superficial, and though they may itch, they're sometimes painful. Tinea barbae often clears by itself in a few days, but deep or recurring folliculitis may need clinical treatment.
Tinea barbae is unfrequent in the United States. Tinea barbae can result in an id reaction, particularly just after starting antifungal treatment. Men are affected almost entirely as the disease involves the bearded areas of the face and neck. Participation of the same areas in healthy women and children is categorized as tinea faciei. The sharing of towels and razors transfers on the highly infectious fungal infection, people who have a chronic runny nose are more possibly to be affected by the bacterial infection, and this kind of the condition is transferred along through air droplets.
A more acute , inflammatory form of the infection appears as pus-filled nodules that ultimately form a crust and that may occur along with swollen lymph nodes and fever. Microsporum canis and Trichophyton mentagrophytes var erinacei may cause tinea barbae but are rare. Tinea barbae arises as superficial annular lesions, but deeper infection alike to folliculitis may occur. The diagnosis of tinea barbae is confirmed by microscopy and culture of skin scrapings and hair pulled out by the roots.
Causes of Tinea barbae
The common causes and risk factor's of Tinea barbae include the following:
- Various dermatophytes, including zoophilic and anthropophilic organisms; though, zoophilic dermatophyte infection occurs more commonly.

Treatment of Tinea barbae
Here is list of the methods for treating Tinea barbae:
- This infection - specially the inflammatory form - can be effectively cured with oral antifungal medications. For excessively stubborn infections, the antifungal medication may be taken by mouth rather than being applied to the skin.
- Treatment is micronized griseofulvin 500 mg to 1 g po once/day till 2 to 3 wk after clinical clearance.
- Avoid shaving the area if possible. If shaving is important, use a clean new razor blade or an electric razor each time.
- Terbinafine 250 mg po once/day and itraconazole 200 mg po once/day have also been used.
