Abstract

Background Tinea corporis is a superficial fungal infection of keratin tissue caused by Dermatophytes. According to observation worldwide Dermatophytes are the most common of the superficial fungal infection. It is common in tropics and may present in epidemic proportions in areas with high rate of humidity, over populations, and poor hygenic conditions. Raichur is a tropical area, hence the present study was taken to find out the clinical patterns of Tinea corporis and to find out fungal species affecting Tinea corporis in Raichur. Methods One hundred patients clinically suspected for Tinea corporis attending Dermatology outpatient and inpatient department of Navodaya Medical College and Research Centre ,Raichur from November 2009 to October 2010 were selected for study specimens. The patients having lesions of papules with scales over the glabrous skin excluding groin was selected for study and scraping from the lesions taken for KOH mount and fungus culture. Results Out of 100 patients the maximum were seen in the age group of 16-30 years (44%), male to female ratio was 1.6:1 ratio. Tinea corporis annular type was the commonest clinical type (45%), followed by Tinea incognito (7%) and Bullous type (4%). Overall positivity by culture was 40%, and direct microscopy (KOH) 96% . T.rubrum was the predominant species isolated(31%) followed by T.mentagrophyte (8%), 54.0% of culture report showed no growth.
