  • Background: Dermatophytes are fungi capable of causing superficial skin, hair and nail infections. A wide variety of clinical presentations are seen. Though worldwide in distribution it is more prevalent in tropical and subtropical countries.There are no recent published data in this regard from South India.

    Aims: To study the disease burden, clinical presentations, risk factors and common species causing dermatophytosis, in Central Kerala, South India

    Methods: Cross sectional study from January 2009 to December 2010.All clinically diagnosed cases of dermatophytosis attending the Dermatology OPD of a tertiary care hospital in South India were included. Patients using antifungal treatment for >3 weeks were excluded. Direct microscopy and culture of relevant samples were done.

    Results: 200 clinically diagnosed cases of dermatophytosis were studied. Majority of patients belonged to 40-49 age group and the disease was rare in children and elderly. Males and females were equally affected. Infection was more common in active workers (52.5%), persons with low socioeconomic status (65.5%) and during summer (67.8%).History of contact with pets was seen in 8.5%.Pruritus and nail discoloration were the predominant symptoms.Skin involvement was seen in 75%, of which Tinea corporis was the predominant type, mainly over the abdomen (66.9%) followed by Tinea cruris. Distal and lateral subungual onychomycosis (DLSO) constituted the major subset(63.1%) of patients with nail infection(41%).8.5% had recurrence of disease. The commonest underlying condition was diabetes mellitus (40%) followed by atopy.KOH was positive in 63.5%(127) and culture positive in 53% (106).Dermatophytes were isolated in 67 cases and in the rest non-dermatophytes were cultured. The commonest dermatophyte isolated was Trichophyton mentagrophytes (46.2%) followed by Trichophyton rubrum (41.7%).Non dermatophyte molds were responsible for most cases of onychomyocosis.

    Conclusion: The study shows the high prevalence of dermatophytosis in middle aged persons living in tropical countries. Trichophyton mentagrophyte was the commonest dermatophyte implicated and skin was the commonest site of affection. Dermatophytosis continues to be a major public health problem in tropics.
