Tinea barbae is a dermatophytosis, a type of fungal infection of the skin and hair that affects the beard area, where typically red patches with scale are seen with dull fragile hair.[2][4] The infection occurs as a superficial folliculitis with small bumps or a deep type (tinea barber profounda) with nodules.[3]

The superficial type is generally caused by Trichophyton violaceum and Trichophyton rubrum, and the deep type by Trichophyton mentagrophytes and T. verrucosum.[2] Farm workers are most at risk.[3]

It is most common among agricultural workers, as the transmission is more common from animal-to-human than human-to-human. The condition was first described by Gruby in 1842.[4]

Signs and symptoms

There are typically red patches with small bumps and crusting around the hairs of the beard and moustache area.[5] The hairs are easily pulled out.[5] It may be itchy or painful to touch.[5]

  • Tinea barbae (superficial)
  • Tinea barbae (deep)
  • Tinea barbae [6]

Causes

The superficial type is generally caused by Trichophyton violaceum and Trichophyton rubrum, and the deep type by Trichophyton mentagrophytes and T. verrucosum.[2]

Mechanism

The transmission of tinea barbae to humans occurs through contact of an infected animal to the skin of a human.[7] Infection can occasionally be transmitted through contact of infected animal hair on human skin. Tinea barbae is very rarely transmitted through human to human contact but is not completely impossible.[7]

Diagnosis

Diagnosis of tinea barbae will firstly include questions being asked from doctors about interactions with farm animals and lifestyle experiences.[7] Doctor will then gain knowledge on possible disease by microscopy, this is viewing the skin under a microscope to get an enlarge view of infected area. Skin scraping and removal of hairs on infected area will occur for medical examination.[5] To acquire causation of tinea barbae putting infected area under ultraviolet light can achieve this, as infection caused by animal and human contact will not show up as fluorescent under the ultraviolet light, compared to other causes of this disease.[7]

Treatment

Topical antifungal medications have limited action, but can be used with oral agents.[3] Common treatment plans for 2-3 weeks in adults

History

The condition was first described by Gruby in 1842.[4]
