Abstract
-
Tinea incognito has been used to describe a dermatophyte infection modified by topical or systemic corticosteroid treatment. Lesions are often atypical appearing and the diagnosis is frequently delayed or missed even though by skilled dermatologists. We present here a 70-year-old female patient who had been treated with topical steroid ointment for the erythematous papules on the face and scalp under the diagnosis of contact dermatitis. Initially the lesions were regarded as a folliculitis, but a potassium hydroxide (KOH) preparation showed many fungal hyphae. A fungal culture grew Trichophyton rubrum.
