Tinea faciei

A 47-year-old woman presented with an itchy, erythematous, scaly plaque with an active border involved most of the lower half of the face of one year duration. The patient had used many topical corticosteroid preparations prescribed by GPs. Of these preparations, clobetasol propionate and betamethasone valerate in cream and ointment bases had been applied for long periods. Each time she noticed partially and transiently improvement on these agents but shortly later deteriorates with extension of the rash. A cure was obtained on oral Griseofulvin 500 mg twice daily for one month.
