BACKGROUND: Tinea capitis is a superficial dermatophytic infection of the scalp and hair shafts, predominantly affecting children. The distribution of etiological agents varies with geography, climate, and socioeconomic factors. Emerging changes in lifestyle and hygiene practices necessitate region-specific epidemiological data.
OBJECTIVES: To determine the prevalence, clinico-epidemiological characteristics, and mycological spectrum of tinea capitis in a tertiary care centre in Southern India, and to evaluate clinico-etiological correlations.
METHODS: A descriptive cross-sectional study was conducted among 70 clinically and mycologically confirmed cases of tinea capitis attending a tertiary care hospital in Madurai, Tamil Nadu, India, from October 2018 to September 2019. Specimens were subjected to 10% potassium hydroxide (KOH) microscopy and fungal culture on modified Sabouraud's dextrose agar. Dermatophytes were identified based on colony morphology and lactophenol cotton blue mount findings. Statistical analysis was performed using the chi-square test, with p < 0.05 considered significant.
RESULTS: The prevalence of tinea capitis was 0.4% among dermatophytosis cases. Most patients (95.6%) were ≤15 years, with male predominance (M:F = 2.04:1). Common risk factors included sharing of combs/caps (44.2%) and tonsuring (38.5%). Non-inflammatory variants predominated (75.7%), with grey patch as the most common presentation (44.3%). Culture positivity was observed in 67.2% of cases. Trichophyton tonsurans (34%) was the predominant isolate, followed by T. violaceum (25.5%) and T. rubrum (14.9%). A significant association was observed between clinical patterns and etiological agents (p < 0.05).
CONCLUSION: Tinea capitis remains a significant pediatric infection in Southern India, with a predominance of anthropophilic dermatophytes, particularly Trichophyton tonsurans, indicating a shift in epidemiological trends. Continuous surveillance and improved hygiene practices are essential for effective control.
