The dermoscopic features of rosacea have already been reported. However, the current findings are incomplete, and little is known about phymatous rosacea. Hence, this study aimed to summarize and compare the dermoscopic features and patterns of three rosacea subtypes (erythematotelangiectatic [ETR], papulopustular [PPR], and phymatous [PHR]) in the Chinese Han population and to evaluate whether these features differ with patients' genders, ages, and durations.
Dermoscopic images of 87 rosacea patients were collected in non-polarized and polarized dermoscopy contact modes at 20-fold magnification. Dermoscopic features, including vessels, scales, follicular findings, and other structures, were summarized and evaluated.
The reticular linear vessels and red diffuse structureless areas of ETR were distinctive. For PPR, red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules were typical dermoscopic criteria. The common dermoscopic features of PHR were: orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines. The following features statistically differed among the three rosacea subtypes: reticular linear vessels ( P < 0.001), unspecific linear vessels ( P = 0.005), linear vessels with branches ( P < 0.001), yellow scales ( P = 0.001), follicular plugs ( P < 0.001), perifollicular white color ( P < 0.001), red diffuse structureless areas ( P = 0.022), orange diffuse structureless areas ( P < 0.001), red focal structureless areas ( P = 0.002), orange focal structureless areas ( P = 0.003), white lines ( P < 0.001), follicular pustules ( P < 0.001), and black vellus hairs ( P < 0.001).
The dermoscopic patterns of ETR are red diffuse structureless areas and reticular linear vessels. For PPR, the pattern comprehends combinations of red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules. Meanwhile, PHR is characterized by remarkable orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines.
已报道酒渣鼻的皮肤镜特征。然而，目前的研究结果并不完整，对酒渣鼻的鼻赘型知之甚少。因此，本研究旨在总结和比较中国汉族人群中三种酒渣鼻亚型（红斑毛细血管扩张型[ETR]、丘疹脓疱型[PPR]和鼻赘型[PHR]）的皮肤镜特征和模式，并评估这些特征是否因患者的性别、年龄和病程而不同。
在非偏振和偏振皮肤镜接触模式下，以 20 倍放大倍数收集 87 例酒渣鼻患者的皮肤镜图像。总结和评估血管、鳞屑、毛囊发现和其他结构等皮肤镜特征。
红斑毛细血管扩张型的特征性皮肤镜表现为网状线性血管和红色弥漫无结构区域。丘疹脓疱型的典型皮肤镜标准为红色弥漫无结构区域、网状线性血管、黄色鳞屑、毛囊栓塞和毛囊脓疱。鼻赘型的常见皮肤镜特征为：橙色弥漫无结构区域、分支状线性血管、毛囊周围白色、橙色局灶性无结构区域和白线。三种酒渣鼻亚型之间的以下特征存在统计学差异：网状线性血管（ P < 0.001）、非特异性线性血管（ P = 0.005）、分支状线性血管（ P < 0.001）、黄色鳞屑（ P = 0.001）、毛囊栓塞（ P < 0.001）、毛囊周围白色（ P < 0.001）、红色弥漫无结构区域（ P = 0.022）、橙色弥漫无结构区域（ P < 0.001）、红色局灶无结构区域（ P = 0.002）、橙色局灶无结构区域（ P = 0.003）、白线（ P < 0.001）、毛囊脓疱（ P < 0.001）和黑色毳毛（ P < 0.001）。
红斑毛细血管扩张型的皮肤镜模式为红色弥漫无结构区域和网状线性血管。丘疹脓疱型的模式包括红色弥漫无结构区域、网状线性血管、黄色鳞屑、毛囊栓塞和毛囊脓疱的组合。同时，鼻赘型的特征是明显的橙色弥漫无结构区域、分支状线性血管、毛囊周围白色、橙色局灶无结构区域和白线。
