17 cases of epidermoid cysts with vellus hairs in their lumen are reported. The clinical diagnosis was usually cysts. In 12 cases the lesions were solitary and in 5 they were multiple, small and closely set. Microscopically, the findings of the wall were those of the epidermoid cyst containing in their lumen hair shafts of lanugo size. The solitary variety of these cysts can be considered as the solitary counterpart of the eruptive vellus hair cyst. Problems of differential diagnosis are discussed.
报告了17例管腔内含有毳毛的表皮样囊肿。临床诊断通常为囊肿。12例病变为单发，5例为多发，囊肿小且密集。显微镜下，囊肿壁表现为表皮样囊肿，管腔内含有胎毛大小的毛干。这些囊肿的单发类型可被视为发疹性毳毛囊肿的单发对应物。文中讨论了鉴别诊断问题。
