Eczema-Like Tinea Incognito Occurring Leg / 대한의진균학회지

ABSTRACT

Tinea incognito is the dermatophytosis of atypical clinical presentation that induced by topical and systemic corticosteroid treatment or new class of topical non-steroidal agent such as tacrolimus or pimecrolimus. We report a case of eczema-like tinea incognito in a 15-year-old girl. The lesions were manifested by pruritic to tender, scaly well-demarcated erythematous macules and patches with pustules on the lateral side of right shin. She had been treated with topical corticosteroid and pimecrolimus for 6 months. Direct microscopic examination of the lesion was positive for hyphae and fungal culture revealed colonies of Trichophyton(T.) rubrum. Histopathologic examination of the skin lesion showed mild perivascular inflammation with presence of fungal hyphae in the horney layer of the epidermis. The patient was treated with 250 mg of terbinafine daily for 1 month and topical lanoconazole application. Skin lesions improved one month after the treatment, and no recurrence was observed.
