Tinea barbae is an uncommon superficial dermatophyte infection of the beard and moustache areas. It was more frequently observed in the past, before single-use razors became available. In most cases, the zoophilic ectothrix Trichophyton mentagrophytes and Trichophyton verrucosum are responsible for this type of infection. Its clinical presentation is variable; it can mimic many other skin disorders such as sycosis, iododerma, contact dermatitis, perioral dermatitis, and actinomycosis. We report a case of tinea barbae caused by an uncommon agent Trichophyton rubrum, misdiagnosed as sycosis, and review the approach and management of the disease.
