Sycosiform tinea barbae caused by Trichophyton rubrum

Area of Science:

• Dermatology
• Mycology
• Infectious Diseases

Background:

• Tinea barbae is an uncommon superficial fungal infection affecting the beard and moustache areas.
• Historically more prevalent, its incidence decreased with the advent of single-use razors.
• Zoophilic ectothrix fungi, primarily Trichophyton mentagrophytes and Trichophyton verrucosum, are the usual causative agents.

Purpose of the Study:

• To report a case of tinea barbae caused by the less common agent Trichophyton rubrum.
• To highlight the diagnostic challenges posed by its variable clinical presentation, which can mimic other dermatoses.
• To review the current approach and management strategies for tinea barbae.

Main Methods:

• Case report presentation.
• Clinical diagnosis and mycological examination.
• Literature review on tinea barbae epidemiology, clinical features, and treatment.

Main Results:

• The case involved Tinea barbae caused by Trichophyton rubrum, initially misdiagnosed as sycosis.
• The variable presentation of tinea barbae can lead to misdiagnosis, mimicking conditions like sycosis, contact dermatitis, and actinomycosis.
• Successful treatment was achieved after accurate diagnosis.

Conclusions:

• Tinea barbae, though uncommon, requires careful diagnostic consideration due to its varied clinical appearance.
• Trichophyton rubrum is an infrequent but possible cause of tinea barbae.
• Prompt and accurate diagnosis is crucial for effective management and to prevent complications.
