Plantar dermatophytosis frequently goes unnoticed and can cause relapse or re-infestation at other sites. The purpose of this study was to evaluate the incidence of plantar dermatophytosis in association with onyxis and intertrigo involving dermatophytes.
This was a retrospective study in patients seen at mycology consultations between January 2002 and December 2003 and for whom culture revealed dermatophytes on the soles, interdigital spaces and/or toe nails. Gender, age and culture data were record from the laboratory workbooks.
716 patients were included, giving 1291 samples. The sex ratio M/F was 1.5 with a mean age of 48 years. Samples of toe nail were obtained from 591 patients, with plantar samples from 433 patients and intertrigo samples from 267 patients. Plantar dermatophytosis was seen in 66.6% of patients with interdigital-plantar signs, in 75.1% of those with ungual involvement and in 73.9% of cases involving both. T. rubrum was the most frequently isolated dermatophyte.
Combine involvement of the sole, nail and/or interdigital space was seen in more than 2/3 of cases. Despite the retrospective nature of our study and the evident bias, our results suggest that plantar dermatophytosis is common and should be sought. The sensitivity and specificity of clinical screening methods merit investigation in a prospective study.
足底皮肤癣菌病常常未被注意到，并且可导致在其他部位复发或再次感染。本研究的目的是评估与累及皮肤癣菌的甲癣和擦烂有关的足底皮肤癣菌病的发病率。
这是一项对2002年1月至2003年12月期间在真菌学门诊就诊且培养显示在足底、趾间和/或趾甲有皮肤癣菌的患者进行的回顾性研究。从实验室工作记录中记录性别、年龄和培养数据。
纳入716例患者，共1291份样本。男女比例为1.5，平均年龄48岁。591例患者获取了趾甲样本，433例患者获取了足底样本，267例患者获取了擦烂样本。在有趾间-足底体征的患者中，66.6%有足底皮肤癣菌病，有甲受累的患者中75.1%有该病，两者都有的病例中73.9%有该病。红色毛癣菌是最常分离出的皮肤癣菌。
超过2/3的病例可见足底、趾甲和/或趾间同时受累。尽管我们的研究具有回顾性且存在明显偏差，但我们的结果表明足底皮肤癣菌病很常见，应该予以排查。临床筛查方法的敏感性和特异性值得在前瞻性研究中进行调查。
