Epidermal inclusion cyst is one of the most common subcutaneous tumors, and its size normally varies from 1 to 5 cm in diameter. Only few giant epidermal inclusion cysts have been reported in the literature, and giant epidermal cyst of the face has never been reported. An 83-year-old woman visited our hospital for a huge mass on the right side of her face extending to the temporal area, creating deformity of her right ear. The mass was 15 × 15 × 8 cm(3) with soft, cystic nature. It has developed since 20 years ago with no known etiology. Computed tomography scan was obtained for preoperative evaluation, which showed a 15 × 15 × 7-cm(3) huge, lobulated, and septated mass with no underlying bone or brain involvement. We performed complete excision sand biopsy. On histologic examination, the final diagnosis of epidermal inclusion cyst was made. Keratotic material was within the cyst, and the cystic wall was composed of lamellate keratin. Follow-up period was 10 months, and no signs of recurrence were seen. The patient was satisfied with the improvement of her facial appearance. We have observed a case of giant epidermal inclusion cyst of the face, which has never been reported, and present this case with a brief review of literature.
表皮样囊肿是最常见的皮下肿瘤之一，其大小通常直径在1至5厘米之间。文献中仅报道过少数巨大表皮样囊肿，面部巨大表皮样囊肿从未见报道。一名83岁女性因右侧面部巨大肿物延伸至颞部就诊我院，导致右耳畸形。肿物大小为15×15×8厘米³，质地柔软，呈囊性。自20年前起发病，病因不明。术前行计算机断层扫描评估，显示为一个15×15×7厘米³的巨大、分叶状且有分隔的肿物，未累及下方骨质或脑部。我们进行了完整切除及活检。组织学检查最终诊断为表皮样囊肿。囊肿内有角化物质，囊壁由层状角质构成。随访10个月，未见复发迹象。患者对面部外观改善满意。我们观察到一例面部巨大表皮样囊肿，此前从未见报道，现报告此病例并简要回顾文献。
