A case of a 30 year-old man with numerous, pink to whitish, 1-2 mm, cystic lesions, located exclusively on the face and helices in symmetrical distribution is reported. Microscopic examination of serial sections of two biopsies disclosed dermal cystic cavities with vellus hair shafts into the lumen. The cyst wall was connected to rudimentary pilar structures. This picture is typical of eruptive vellus hair cysts (EVHC). Facial variant of this dermatosis is reported only in two cases in the literature. Histogenesis and differential diagnosis are discussed.
报告了一例30岁男性病例，其面部和耳轮上有许多粉红色至白色、1-2毫米的囊性病变，呈对称分布。对两份活检标本的连续切片进行显微镜检查，发现真皮囊性腔内有毳毛干伸入管腔。囊壁与原始毛囊结构相连。此表现为发疹性毳毛囊肿（EVHC）的典型特征。文献中仅报道过两例这种皮肤病的面部变异型。文中讨论了其组织发生及鉴别诊断。
