METHODS: This study was carried out in two stages. We performed a multicentre, cross-sectional study in 23 French dermatology centers. All children seen for psoriasis during the one-year study were systematically included. The clinical features of the tongue and of psoriasis were recorded. Association with clinical aspects of psoriasis and comorbidities was evaluated. We then carried out a literature review to evaluate the prevalence of tongue involvement in children with psoriasis and its positive predictive value for psoriasis. A search was conducted in the PUBMED database using the following keywords: \"child\" and \"psoriasis\" and (\"tongue\" or \"glossitis\" or \"migratory glossitis\" or \"benign migratory glossitis\" or \"geographic tongue\" or \"fissured tongue\").
RESULTS: 7.7% of the 313 children with psoriasis had tongue involvement. The clinical aspects were geographic tongue (4.2%), fissured tongue (2.8%) and both (0.64%). There was no association between tongue involvement and the clinical characteristics of the children. Two hundred and ninety-five articles were referenced and 3 were analysed. Psoriasis is very rare in cases of tongue abnormalities.
CONCLUSIONS: The prevalence of tongue involvement was 7.7% in children with psoriasis. No clinical or epidemiological association was shown. Tongue involvement does not modify the management of psoriasis. In the literature review it was not possible to evaluate either the prevalence of tongue involvement in psoriasis or the positive predictive value thereof.
方法:本研究分两个阶段进行。我们表演了一个多中心,23个法国皮肤病学中心的横断面研究。在为期一年的研究中,所有患有牛皮癣的儿童均被系统地纳入。记录舌和银屑病的临床特征。评估了与银屑病和合并症的临床方面的关联。然后,我们进行了文献综述,以评估银屑病儿童中舌头受累的患病率及其对银屑病的阳性预测价值。在PUBMED数据库中使用以下关键字进行搜索:\“儿童\”和\“牛皮癣\”和(\“舌头\”或\“舌炎\”或\“迁徙性舌炎\”或\“良性迁徙性舌炎\”或\“地理舌头\”或\“裂开的舌头”)。
结果:313例银屑病患儿中,有7.7%有舌头受累。临床方面为地理舌(4.2%),裂舌(2.8%)和两者(0.64%)。舌头受累与儿童的临床特征之间没有关联。引用了二百九十五篇文章,分析了三篇。牛皮癣在舌头异常的情况下非常罕见。
结论:银屑病患儿舌部受累的患病率为7.7%。未显示临床或流行病学关联。舌头受累不会改变牛皮癣的治疗。在文献综述中,不可能评估银屑病中舌受累的患病率或其阳性预测值。
