Tinea Incognito Caused by Application of 0.03% Tacrolimus (Protopic(R)) Ointment in Atopic Dermatitis Patient / 대한의진균학회지

ABSTRACT

We report a case of tinea incognito in a 29-year-old man after applying the 0.03% tacrolimus ointment. He was known atopic dermatitis patient and has been treated with intermittent application of tacrolimus. For his facial pruritus 0.03% tacrolimus ointment was prescribed, and after one week he developed annularly grouped erythematous plaques and patches around the ointment-applied area. The KOH smear revealed multiple fungal hyphae. Dermatologists should be aware of the possibility of topical tacrolimus to be the causative agent for tinea incognito.
