Tinea corporis is a superficial dermatophyte infection. This is a case report of a 45-year-old female presenting with a history of erythematous raised lesions with itching all over the body since one year ago. Based on clinical findings, the lesions were diagnosed as tinea corporis. A KOH smear was carried out and results were negative probably due to application of steroids, and a histopathological examination was done. On histopathological examination, the patient was proved to have dermatophytosis caused by Trichophyton mentagrophytes. The patient was successfully treated with oral itraconazole 200mg once a day and griseofulvin 250 mg once a day along with 2 % ketoconazole for topical application.
