Tinea capitis in Pondicherry (South India)

|March 1, 1975

Summary

Tinea capitis, a common fungal infection, accounted for 12.5% of skin mycoses. Trichophyton violaceum was the primary cause in 84% of positive cases.

Area of Science:

Background:

Tinea capitis is a prevalent superficial fungal infection affecting the scalp.
Dermatomycoses encompass a range of fungal skin infections with varying clinical presentations.
Understanding the epidemiology and causative agents of tinea capitis is crucial for effective management.

Purpose of the Study:

To analyze the clinical characteristics and mycological profile of tinea capitis cases.
To determine the prevalence of tinea capitis within the spectrum of dermatomycoses.
To identify the predominant fungal species responsible for tinea capitis infections.

Main Methods:

Retrospective analysis of 125 cases diagnosed with tinea capitis.
Assessment of the proportion of tinea capitis among all dermatomycosis cases.
Clinical examination for associated lesions such as kerion, tinea corporis, and tinea unguium.
Mycological examination (fungal culture) for pathogen identification.

Main Results:

Tinea capitis represented 12.5% of all dermatomycosis cases studied.
Approximately 9% of tinea capitis cases presented with kerion-like lesions.
A further 13% of cases exhibited concurrent tinea corporis and/or tinea unguium.
Mycological analysis confirmed infection in 84% of cases.
Trichophyton violaceum was identified as the causative agent in 84% of positive cultures.
Trichophyton tonsurans accounted for the remaining 16% of identified pathogens.

Conclusions:

Tinea capitis is a significant component of dermatomycosis, often presenting with diverse clinical manifestations.
Trichophyton violaceum is the dominant species causing tinea capitis in this cohort.
Co-infection with other dermatophyte infections like tinea corporis and tinea unguium can occur.
