The incidence of tinea incognito (TI) appears to have increased over recent years, although no large series of cases has been reported in children. The aim of this study was to analyse the main epidemiological, clinical and microbiological characteristics of TI diagnosed in children in comparison with other tineas. We undertook a retrospective study of 818 tineas diagnosed in children in a referral hospital between 1977 and 2006, concentrating on TI. Of the 54 TI diagnosed, 85% were in the last 15 years. Most children were older than 9 years of age. The most usual clinical forms were tinea corporis (46.3%) and tinea faciei (38.9%). Topical steroids alone had been used to treat 68.5% of the cases. Direct examination was positive in 91.5% of the cases examined. Culture was positive in 85.2% of cases. The most frequently isolated dermatophyte was Trichophyton mentagrophytes (44.4%). This is the largest case series of childhood TI reported to date. TI has increased over recent years and important differences were found between these TI and the other tineas in children over the same period.
隐性体癣（TI）的发病率近年来似乎有所增加，尽管尚未有大量儿童病例的报道。本研究旨在分析在一家转诊医院 1977 年至 2006 年间诊断的儿童 TI 的主要流行病学、临床和微生物学特征，并与其他体癣进行比较。我们对在转诊医院诊断的 818 例儿童体癣进行了回顾性研究，重点分析 TI。54 例 TI 中，85%为近 15 年来发病。多数患儿年龄>9 岁。最常见的临床类型为体癣（46.3%）和面癣（38.9%）。68.5%的病例曾单独使用过外用皮质类固醇。91.5%的病例直接镜检阳性。85.2%的病例培养阳性。最常分离到的皮肤癣菌是须癣毛癣菌（44.4%）。这是迄今为止报道的最大一组儿童 TI 病例。近年来 TI 发病率有所增加，且与同期儿童的其他体癣相比，TI 存在重要差异。
