摘要：

目的 评估Wood灯在皮肤常见浅表真菌感染诊断中的应用价值。方法 对129例根据临床病史及体征初步诊断为皮肤浅表真菌感染患者进行Wood灯和真菌实验室检查。结果 花斑糠疹、马拉色菌毛囊炎患者Wood灯检查的阳性率分别为84%、85.7%，同时阳性病例的真菌培养或镜检的阳性率达92.9%、87.5%，两者有高度的一致性。而临床诊断手足癣和体股癣者其荧光阳性率只有8.3%，真菌总检出率却高达85.4%（41/48），两者不具有一致性。结论 Wood灯在花斑糠疹、马拉色菌毛囊炎的检查上有较高的特异性和敏感性，临床诊断上有应用价值，而对手足癣和体股癣诊断则无意义。

Abstract:

Objective To estimate the performance of Wood′s lamp examination in the diagnosis of superficial cutaneous fungal infections. Methods Totally, 129 patients, who were diagnosed with superficial cutaneous fungal infections according to clinical medical history and signs, were enrolled in this study. Wood′s lamp examination of lesions was carried out. Cutaneous samples were obtained from the patients and subjected to microscopic examination and fungal culture. Results Wood′s lamp examination was positive in 84% and 85.7% of patients with tinea versicolor and malassezia folliculitis, respectively; among these patients positive for Wood′s lamp examination, 92.9% were positive for fungal culture, and 87.5% for microscopic examination. In patients clinically diagnosed with tinea manus and pedis, tinea corporis or tinea cruris, 8.3% were positive for Wood′s lamp examination, while 85.4% were positive for fungal examination. There was a high consistency between Wood′s lamp examination and fungal examination in patients with tinea versicolor and malassezia folliculitis, but not in those with tinea manus and pedis, tinea corporis or tinea cruris. Conclusions Wood′s lamp examination shows a high specificity and sensitivity and is useful in the diagnosis of tinea versicolor and malassezia folliculitis, but seems unapplicable for the diagnosis of tinea manus and pedis, tinea corporis or tinea cruris.
