An epidermal cyst is a common keratin-filled epithelial-lined cyst. The treatment of choice for epidermal cysts is surgical excision. If the cyst becomes ruptured, incision and drainage with oral antibiotic therapy or intralesional steroid injection are required.
To analyze the dermoscopic features that can differentiate between ruptured and unruptured epidermal cysts.
The clinical and dermoscopic features of the pathologically confirmed epidermal cysts of two subgroups of 38 patients, 20 with unruptured cysts and 18 with ruptured cysts, were reviewed.
With regard to the dermoscopic features, an ivory- white background color and punctum were commonly found in both groups (>0.05). The unruptured-cyst group showed higher frequencies of pore sign (<0.05), blue-white veil (>0.05), no vascular structure, and arborizing telangiectasia (<0.05), but the ruptured-cyst group usually had red lacunae (>0.05) and peripheral linear branched vessels (with an erythematous rim) (<0.05).
Dermoscopy is helpful in differentiating between ruptured and unruptured epidermal cysts.
表皮囊肿是一种常见的充满角蛋白的上皮内衬囊肿。表皮囊肿的首选治疗方法是手术切除。如果囊肿破裂，则需要切开引流并进行口服抗生素治疗或病灶内注射类固醇。
分析可区分破裂和未破裂表皮囊肿的皮肤镜特征。
回顾了38例经病理证实的表皮囊肿患者两个亚组的临床和皮肤镜特征，其中20例为未破裂囊肿，18例为破裂囊肿。
在皮肤镜特征方面，两组均常见象牙白色背景色和小孔（>0.05）。未破裂囊肿组的毛孔征（<0.05）、蓝白色面纱（>0.05）、无血管结构和树枝状毛细血管扩张（<0.05）出现频率较高，但破裂囊肿组通常有红色腔隙（>0.05）和周边线性分支血管（伴有红斑边缘）（<0.05）。
皮肤镜有助于区分破裂和未破裂的表皮囊肿。
