Summary
This 16-year study in Southeastern China found increasing tinea capitis incidence, peaking in 2001. Microsporum canis was the predominant pathogen, especially in ectothrix infections.
Area of Science:
- Mycology
- Dermatology
- Infectious Diseases
Background:
- Tinea capitis is a common fungal infection of the scalp.
- Understanding its epidemiology and causative agents is crucial for public health.
- Southeastern China has specific regional patterns of this infection.
Purpose of the Study:
- To analyze the incidence, clinical features, and etiological agents of tinea capitis.
- To provide a comprehensive overview of scalp ringworm over a 16-year period.
- To identify trends and predominant pathogens in Southeastern China.
Main Methods:
- Retrospective study from 1993 to 2008.
- Involved 866 patients diagnosed with tinea capitis.
- Diagnosis confirmed by direct microscopic examination and fungal culture.
Main Results:
- Incidence increased from 1993, peaking in 2001.
- Microsporum canis (62.4%) was the most common pathogen, followed by Trichophyton violaceum (19.0%).
- M. canis predominated in ectothrix infections, while T. violaceum and T. tonsurans caused endothrix infections.
Conclusions:
- Tinea capitis incidence showed an upward trend in Southeastern China during the study period.
- Microsporum canis is the primary cause of tinea capitis in this region.
- Specific dermatophytes are linked to ectothrix and endothrix forms, as well as kerion development.
