Trichophyton tonsurans infection was found first in autumn 2000 in Gifu prefecture and spread rapidly in the Tokai region. Not only direct KOH examination but also culture is necessary to diagnose this disease. In order to collect a specimen, I recommend cellophane adhesive tape. During the past 5 years, dermatologists in the Tokai area have sent me specimens in an envelope for mycological examination. Hyphae were found in all 75 cases in the scales examined. Fungal culture revealed 61 cases to be T. tonsurans infection; the male : female ratio was 54 : 7. By age distribution, high school students accounted for 46 (75%), elderly patients 9 (15%) and lower age 6 (10%). Judo players accounted for 32 (52%), wrestlers for 24 (39%) and others for 5 (8%). Most had lesions on the face, neck, head or arm. One wrestler had a nail involvement. In some specimens from tinea corporis, hyphae in the hair shaft were observed. This sort of tinea epidemic probably occurs more often than is reported. Therefore we have begun to cooperate with a medical department member of the Gifu Judo Society to prevent of T. tonsurans infection.
2000年秋季，在岐阜县首次发现断发毛癣菌感染，并在东海地区迅速传播。诊断这种疾病不仅需要直接进行氢氧化钾检查，还需要进行培养。为了采集标本，我推荐使用透明胶带。在过去的5年里，东海地区的皮肤科医生将标本装在信封里寄给我进行真菌学检查。在所检查的鳞屑中，75例均发现菌丝。真菌培养显示61例为断发毛癣菌感染；男女比例为54:7。按年龄分布，高中生占46例（75%），老年患者占9例（15%），低龄患者占6例（10%）。柔道运动员占32例（52%），摔跤运动员占24例（39%），其他占5例（8%）。大多数患者的面部、颈部、头部或手臂有病变。一名摔跤运动员指甲受累。在一些体癣标本中，观察到毛干内有菌丝。这种癣病的流行可能比报道的更为常见。因此，我们已开始与岐阜柔道协会的一名医学部成员合作，以预防断发毛癣菌感染。
