Comma and corkscrew hairs are trichoscopic markers of tinea capitis. Although comma hairs have been reported in both black and white patients with tinea capitis, corkscrew hairs were previously hypothesized to manifest exclusively in patients with curly or African hair types. However, we report a significant number of comma and corkscrew hairs in a Hispanic female patient with naturally straight hair and Trichophyton tonsurans tinea capitis. Thus, dermoscopy is a rapid, noninvasive, and cost-effective tool for evaluating tinea capitis and should be used in combination with culture in all patients regardless of hair texture or race.
逗号状发和螺旋状发是头癣的皮肤镜特征。虽然在患有头癣的黑人和白人患者中均有逗号状发的报道，但此前推测螺旋状发仅见于卷发或非洲发型的患者。然而，我们报告了一名患有须癣毛癣菌性头癣、自然直发的西班牙裔女性患者出现大量逗号状发和螺旋状发。因此，皮肤镜检查是一种快速、无创且经济高效的评估头癣的工具，无论患者头发质地或种族如何，均应与培养检查联合用于所有患者。
