皮疹の一部からScopulariopsisが分離されたTrichophyton rubrumによる汎発性白癬

・背部，左踵，両足趾爪からScopulariopsis（S.）brevicaulisが分離されたTrichophyton （T.）rubrumによる汎発性白癬を経験した．

・足趾爪以外の体の皮疹からS. brevicaulisが分離されることはまれである．

・S. brevicaulisが分離された背部の皮疹も含め皮疹は塩酸テルビナフィン内服とルリコナゾール軟膏治療により約2カ月間で消褪した．

A 74-year-old man with widespread tinea caused by Trichophyton rubrum presented with multiple annular lesions. Samples obtained from lesions on his back, left heel, and toe nails were cultured. Scopulariopsis brevicaulis was among pathogens isolated from each lesion. His tinea corporis, including back and heel lesions, was successfully treated with oral terbinafine and topical luliconazole. Scopulariopsis, a keratinolytic fungus, is a known causative agent of onychomycosis. Its isolation from other than nail lesions is extremely rare. Whether this species was a contaminant or concomitant pathogen was not confirmed or disproved. The pathogenicity of Scopulariopsis has been discussed.
