White piedra is a rare hair infection of man and certain animals, caused by the widespread Trichosporon fungi. The infection is characterized clinically by whitish, soft and easily removable coating of the hair shafts; however, the shafts may be destroyed by the pathogens invading at localized points. While all body hair may be affected, the pubic hair is most frequently affected. This paper is the first report genital white piedra in a 34-year-old Central European man. In all, 22 cases have been described world-wide in young men ranging in age from 20 to 40 years. Only 2 men, aged 42 and 53 years, do not fall in this range. Recently, a major African study disclosed this disease in women for the first time. In moderate latitudes, however, this infection appears to occur almost exclusively in young men.
白癣是一种发生于人类和某些动物的罕见毛发感染病，由广泛存在的毛孢子菌属真菌引起。临床上，这种感染的特征是毛干上有白色、柔软且易于去除的覆盖物；然而，毛干可能会被在局部点侵入的病原体破坏。虽然全身毛发都可能受到影响，但阴毛最常受累。本文首次报道了一名34岁中欧男性的生殖器白癣病例。全世界共描述了22例年龄在20至40岁之间的年轻男性病例。仅有2名年龄分别为42岁和53岁的男性不在此年龄范围内。最近，一项重要的非洲研究首次在女性中发现了这种疾病。然而，在中纬度地区，这种感染似乎几乎只发生在年轻男性身上。
