Abstract：
Facial angiofibromas are benign tumors presenting as firm, dome-shaped, flesh-colored to pink papules, typically on the nose and adjoining central face. Clinically and dermoscopically they can mimic melanocytic nevi or basal cell carcinomas (BCC). Reflectance confocal microscopy (RCM) is a noninvasive imaging tool that is useful in diagnosing melanocytic and non-melanocytic facial lesions. To date no studies have described the RCM features of facial angiofibromas. Herein, we present two cases of facial angiofibromas that were imaged with RCM and revealed tumor island-like structures that mimicked BCC, leading to skin biopsy.
摘要：
面部血管纤维瘤是良性肿瘤，表现为坚硬，圆顶形,肉色到粉红色的丘疹,通常在鼻子和毗邻的中央面上。在临床和皮肤镜下，它们可以模拟黑素细胞痣或基底细胞癌（BCC）。反射共聚焦显微镜（RCM）是一种非侵入性成像工具，可用于诊断黑素细胞和非黑素细胞面部病变。迄今为止，尚无研究描述面部血管纤维瘤的RCM特征。在这里，我们介绍了两例面部血管纤维瘤，用RCM成像，并显示了模仿BCC的肿瘤岛状结构，导致皮肤活检。
