Four Cases of Tinea Corporis Caused by Microsporum gypseum / 대한의진균학회지

ABSTRACT

Microsporum (M.) gypseum is geophilic and abundant in soil throughout the world. The source of human infection has been traced to soil or animals. But tinea corporis caused by M. gypseum is rare. We report 4 cases of tinea corporis caused by M. gypseum in a 38 year-old female, a 7 year-old girl, a 2 year-old boy, and a 18 year-old female. The lesions were manifested by localized pruritic fine scaly erythematous annular patches on the shin, forearm, neck, and antecubital fossa. Direct microscopic examination of scales on the potassium hydroxide preparation showed hyphae and spores in 3 cases. But cultures from the skin lesion of all patients on Sabouraud dextrose agar showed typical colonies of M. gypseum. The patients were treated with topical ketoconazole application and/or oral antifungal agents.
