Introduction: Tinea incognito is a localized skin infection caused by a fungus. Due to the use of corticosteroids, the shape and severity of the lesion are different from the usual skin manifestations by dermatophytes.
Background and Aim: A 39-year-old female with history of erythematous, scaly skin lesions on her hands, buttock, inguinal and both legs for 7 months referred to clinician, who prescribed Calamine-D and hydrocortisone without any treatment and clobetazole was recomended. She self-continued clobetazole. This case highlight the importance of mycological test in case of atypical skin lesions to choose an appropriate treatment and avoiding to spread of drug resistance species.
Methods: Regarding to history of patient, the mycological test (Direct Microscopy and culture) was made. In direct microscopy and culture mycelia of dermatophyte species was seen.
Results: In our case steroid discontinued and she was treated with oral terbinafine 250 mg once a day for 4 weeks in combination with topical clotrimazole cream.
Conclusion: the prescription of topical/oral corticosteroids should still be limited and take a caution until confirmation of diagnosis, particularly since the use of steroids during COVID 19.
