A 63-year-old woman presented withpruritic, scaly, erythematous plaques on the post. neck and trunk which had started 2 months ago. Alsoher 9-year-old granddaughter presented with pruritic, annular, erythematous plaques on chest and backfor 7 days. They denied contact with animals. KOH smear showed several hyphaes on microscope. Fungus culture on potato dextrose agar showed growth of colonies with whitish fluffy surface and radialfolds, the dorsal surface of the colonies showed golden-brown color which were identified as M. canisin both patients. As for the grandmother the lesions improved with oral itraconazole 200 mg/day for 7days and topical antifungal cream for 5 weeks which resulted in marked improvement of the lesions.
