Area of Science:

  • Dermatology
  • Mycology
  • Infectious Diseases

Background:

  • Tinea capitis, a fungal infection of the scalp, exhibits diverse clinical presentations.
  • The specific fungi causing tinea capitis differ geographically and evolve over time.
  • Understanding local etiologic agents is crucial for effective diagnosis and treatment.

Purpose of the Study:

  • To identify the causative fungal agents of tinea capitis in Lahore, Pakistan.
  • To correlate the clinical presentation of tinea capitis with its identified etiologic agents.

Main Methods:

  • Collection of skin scrapings and hair samples from clinically suspected cases.
  • Microscopic examination of samples to detect fungal elements.
  • Fungal culture to isolate and identify specific dermatophyte species.

Main Results:

  • 100 patients were evaluated, with 95% being children under 12 years old.
  • Non-inflammatory lesions occurred in 56.4% and inflammatory lesions in 43.6% of cases.
  • Trichophyton violaceum was the predominant pathogen (82%), followed by T. tonsurans (8%), T. verrucosum (5%), and T. mentagrophytes (5%).

Conclusions:

  • Trichophyton violaceum is the most common fungus responsible for tinea capitis in Lahore.
  • The identified predominant pathogen, T. violaceum, is associated with a wide spectrum of clinical manifestations.
