Abstract:

Three cases of dermatophytoses caused by Microsporum gypseum with various clinical manifestations were reported. Case 1 developed exudative erythema on the scrotum overlying white paint dot-like incrustation for 1 month. His father had the similar problem and they had shared a same pants. The father had frequent contact with domestic cat. Case 2 presented with a coin-sized erythema with crusts in the middle and exudation in the border on the left side of his face for 2 weeks after local abrasion. Case 3 had a coin-sized, well-circumscribed erythema overlying scattered papules and scales for 3 weeks. She occasionally played with the cat at home. A large amount of hyphea were noticed from the lesion by direct microscope examination. Fungal colonies developed on Sabouraud dextrose agar (SDA) after inoculating for 2 weekswere identified as Microsporum gypseum. The lesions resolved completely after topical use of different antimycotic agents or oral itraconazole capsules for 1-2 weeks.
