Thirty-one cases of trichilemmoma of the eyelid and eyebrow were studied. All lesions were solitary, small, and asymptomatic. Unlike basal cell carcinoma of the eyelid, trichilemmoma rarely involves the lid margin or the inner canthus. The age range of our patients was from 22 to 88 years old (mean, 56 years). There were 19 men and 12 women. The most frequent clinical diagnoses were verruca vulgaris and cutaneous horn. Typically, the tumor displayed a lobular pattern and was composed mostly of glycogen-rich clear cells. The periphery of the lobules showed palisading of columnar cells and a distinct basement membrane. Histologically, the tumor was frequently misinterpreted as basal cell carcinoma. Review of the literature, including our own series, discloses that the eyelid is the second most common site for trichilemmoma after the nose.
对31例眼睑和眉部毛发上皮瘤进行了研究。所有病变均为单发、体积小且无症状。与眼睑基底细胞癌不同，毛发上皮瘤很少累及睑缘或内眦。我们患者的年龄范围为22至88岁（平均56岁）。男性19例，女性12例。最常见的临床诊断为寻常疣和皮角。典型情况下，肿瘤呈小叶状，主要由富含糖原的透明细胞组成。小叶周边可见柱状细胞呈栅栏状排列及明显的基底膜。组织学上，该肿瘤常被误诊为基底细胞癌。回顾文献，包括我们自己的系列研究，发现眼睑是毛发上皮瘤继鼻部之后的第二常见部位。
