Microsporum canis-Induced Tinea Capitis: A Rapid Screening Algorithm

Area of Science:

• Dermatology
• Mycology
• Pediatrics

Background:

• Tinea capitis is a common superficial fungal infection of the scalp, predominantly affecting children.
• Caused by dermatophytes such as Trichophyton and Microsporum species.
• Pathogenesis involves host and environmental factors, leading to diverse clinical manifestations like alopecia and scaling.

Observation:

• A case of an eight-year-old male with symptomatic tinea capitis is presented.
• Clinical presentation included pruritus and occipital hair loss.
• Trichoscopy revealed characteristic findings, and direct hair examination confirmed fungal parasitization.

Findings:

• The patient was treated with oral terbinafine.
• Successful resolution of tinea capitis symptoms was achieved.
• Global epidemiological data shows regional variations in causative dermatophyte species.

Implications:

• Trichoscopy is an effective diagnostic method for fungal infections, aiding treatment selection.
• Integrating trichoscopy with clinical and epidemiological data can create a rapid in-office diagnostic tool.
• This approach addresses challenges posed by the prevalence of tinea and limited access to mycological centers.
