A Case of Tinea Corporis caused by Microsporum Incurvatum - a Geophillic Species related to M. gypseum
Abstract
We present a case of mycotic infection of tinea corporis type in a forty-year old woman. The lesion was localised on the dorsal aspect of the left hand and did not react to ciclopirox olamine.
The systemic therapy by terbinafine was stopped because of its side effects. The lesion was treated successfully with local antimycotics naftifine and natamycin.
The geophillic dermatophyte Microsporum incurvatum was isolated and verified by the sequencing of ITS rDNA. This dermatophyte is rarely isolated from clinical material and probably no case was described in the Czech Republic.
It is possible that some infections caused by M. incurvatum are attributed to M. gypseum and M. fulvum due to morphologic similarity of these species. The controversial taxonomy of this species and possibility of its differentiation from other species is discussed as well.
