Digital mucous cysts (DMC) are common benign myxoid cysts typically located on the fingers and toes. Recently, dermoscopic patterns of DMC were reported. However, only a small number of cases were described in the published work; therefore, information on this topic is scarce in the published work. We investigated dermoscopic patterns of histopathologically diagnosed DMC. In total, 23 cases were enrolled in this study. Polarized dermoscopy revealed vascular patterns in 13 cases (56.5%), with arborizing vascular patterns, dotted vessels, linear vessels and polymorphous vessels in eight (34.8%), three (13.0%), one (4.3%) and one (4.3%) case, respectively. Red-purple lacunas, ulceration, nail dystrophy and white shiny structures were detected in five (21.7%), two (8.7%), seven (30.4%) and six cases (26.1%), respectively. We report the largest case series regarding dermoscopic features of DMC to date. Dermoscopy can be used as a helpful adjuvant and non-invasive tool in the diagnosis of DMC.
数字粘液囊肿（DMC）是常见的良性黏液样囊肿，通常位于手指和脚趾上。最近，报道了 DMC 的皮肤镜模式。然而，在已发表的文献中仅描述了少数病例；因此，关于该主题的信息在已发表的文献中很少。我们研究了组织病理学诊断的 DMC 的皮肤镜模式。本研究共纳入 23 例病例。偏振皮肤镜显示 13 例（56.5%）存在血管模式，其中 8 例（34.8%）为树枝状血管模式，3 例（13.0%）为点状血管模式，1 例（4.3%）为线性血管模式，1 例（4.3%）为多形性血管模式。发现 5 例（21.7%）存在红紫色腔隙，2 例（8.7%）存在溃疡，7 例（30.4%）存在指甲营养不良，6 例（26.1%）存在白色闪亮结构。我们报告了迄今为止关于 DMC 皮肤镜特征的最大病例系列。皮肤镜检查可作为 DMC 诊断的一种有用的辅助和非侵入性工具。
