Epidermal cysts are commonly encountered in surgical practice. Malignant degeneration of epidermal sebaceous cyst is uncommon. The authors report the case of a 38-year Filipino woman presenting with a voluminous sebaceous cyst of the left buttock. Ultrasonography and computer tomography were made preoperatively without any hint of eventual malignant degeneration. Marginal excision was performed with direct closure of the skin. The histological examination revealed epidermal sebaceous cyst with squamous cell carcinoma in situ, which is a quite rare, but well known complication occurring in sebaceous cysts.
表皮囊肿在外科手术中很常见。表皮皮脂腺囊肿的恶性变并不常见。作者报告了一例38岁菲律宾女性，其左臀部有一个巨大的皮脂腺囊肿。术前进行了超声检查和计算机断层扫描，未发现最终恶性变的任何迹象。进行了边缘切除并直接缝合皮肤。组织学检查显示为表皮皮脂腺囊肿伴原位鳞状细胞癌，这是皮脂腺囊肿中一种相当罕见但众所周知的并发症。
