Introduction: Tinea incognita is a dermatosis that is difficult to identify due to the prolonged and erroneous use of corticosteroids, which can simulate other inflammatory skin diseases. Methods and results: We present the case of a patient with progressive growth of an annular plaque on the dorsum of the right foot after two months of chronic use of a topical corticosteroid that partially controlled the clinical symptoms, but when the medication was suspended, culture revealed Trichophyton tonsurans. A diagnostic impression of corticosteroid-modified tinea was made, and the dermatophyte infection was managed systemically and topically.
Conclusions: The prescription of topical or oral steroids should be limited unless there is confirmation of the microorganism related to the clinical manifestations, since it can mask the diagnosis and delay timely treatment of dermatophytosis.
