We report a clinicomycologic study of eight culture-proven cases (diagnosed from May 1991 to June 1992) of Trichophyton tonsurans (T. tonsurans) infection in Tainan. T. tonsurans is the most common cause of tinea capitis in the United States and Mexico; Trichophyton violaceum (T. violaceum) is the most common cause in South Africa, India, Jordan and the Far East. To date, there has been no written report of infection caused by T. tonsurans in Taiwan. We report six cases of tinea capitis and two cases of tinea corporis which were proven to be T. tonsurans infection. In this small series, as in our previous series on T. violaceum infection, a predominance of adults of the female gender was noted. The median age of the adults was 58 years. The only child patient was an eight-year-old girl with tinea capitis whose mother was also infected. We have observed T. tonsurans infection with an increasing frequency over the last two years in Tainan. In the future, one would expect an increased incidence of T. tonsurans infections in other parts of the country, especially in adjoining cities. Dermatologists should be increasingly alerted to the possibilities of T. tonsurans as an etiologic agent in fungal infection.
我们报告了一项针对8例经培养证实的须癣毛癣菌（T. tonsurans）感染病例的临床真菌学研究（这些病例于1991年5月至1992年6月在台南被诊断）。须癣毛癣菌是美国和墨西哥头癣最常见的病因；紫色毛癣菌（T. violaceum）是南非、印度、约旦和远东地区最常见的病因。迄今为止，台湾尚无关于须癣毛癣菌感染的书面报告。我们报告了6例头癣和2例体癣病例，这些病例经证实为须癣毛癣菌感染。在这个小系列中，如同我们之前关于紫色毛癣菌感染的系列研究一样，发现女性成年人占多数。成年患者的中位年龄为58岁。唯一的儿童患者是一名患有头癣的8岁女孩，其母亲也被感染。在过去两年里，我们在台南观察到须癣毛癣菌感染的频率不断增加。未来，预计该国其他地区，尤其是毗邻城市，须癣毛癣菌感染的发病率将会上升。皮肤科医生应越来越警惕须癣毛癣菌作为真菌感染病原体的可能性。
