Tinea incognito due to Trichophyton rubrum--a case report.
Abstract
Tinea
incognito is a dermatophyte infection modified by inappropriate and
often prolonged use of topical steroids. We present a case of tinea
incognito in a 72-year-old woman, referred by her family physician who
had unsuccessfully treated the lesions for 3 weeks with topical steroid
cream. Physical examination revealed multiple nummular scaly papules and
plaques which spread over her arms and trunk. The lesions were
circular, erythematous, sharply demarcated with raised scaly edge some
coalescing to form moderately infiltrated areas. Direct microscopy was
positive for fungal hyphae. Fungal culture on Sabouraud's agar grew
Trichophyton rubrum. The patient was successfully treated with oral
terbinafine 250 mg daily and 1% clotrimazole cream twice daily. The
present case highlights the importance of considering a dermatophytosis
when clinical presentation of dermatosis is atypical. Disseminated scaly
infiltrate lesions should be investigated for fungal infection in
patients previously treated with steroids, as to avoid misdiagnosis and
spread of infection.
