Abstract


Objective To determine the clinicomycological pattern of dermatophytosis in patients attending tertiary care dermatology centre.

 

Methods All patients attending Dermatology OPD, Sir. T. General Hospital, Bhavnagar, clinically diagnosed of dermatophytosis, were subjected to direct microscopy in KOH solution and culture on Sabouraud’s dextrose agar medium. Fungal species were identified on the basis of cultural characteristics, pigment production and microscopic examination in lactophenol cotton blue preparation.

 

Results Out of the 530 cases, majority of patients were in the age group of 30-40 years and male to female ratio of 1.2:1. Majority of the patients were housewives, followed by laborers. 70.9% patients were diagnosed of having tinea corporis, followed by tinea cruris (17.7%) and 52.3% of patients showed positivity in KOH smear and culture was positive in 32.1% cases.  Most commonly isolated species was Trichophyton rubrum, followed by T. mentagrophytes and least was T. tonsurans (0.2%).

 

Conclusion Tinea corporis was the commonest clinical type of all dermatophytoses. Trichophyton rubrum was the most common isolate, thus concluding that it is the most common cause of superficial dermatophytic infection.
