A prospective observational study was conducted with the patients attending the Skin and STD outpatient unit of a tertiary care teaching hospital in Salem.

A total of 420 dermatophytosis patients were included giving a percentage prevalence of 13.69%. There were more female patients (n = 213, 50.71%) than males (n = 207, 49.29%). The most common afflicted age group was 31-40 years (n = 99, 50.71%). Most of the patients had an atypical lesion called tinea incognita (n = 265, 63.09%) where there was no typical classic appearance of dermatophytic infections. The most prevalent clinical manifestation was tinea corporis (n = 73, 17.38%) followed by tinea cruris (n = 69, 16.43%). There were more newly diagnosed dermatophytosis cases (n = 326) than the previously diagnosed cases (n = 94). This study concludes that dermatophytic mycoses were more prevalent among females than males and among the age groups of 31-40 years. The most common clinical presentation was tinea incognita followed by tinea corporis.
