A 72-year-old male presented with a large ulceroproliferative lesion over left gluteal region. After histopathological confirmation of squamous cell carcinoma, the lesion was excised with wide margins. Further histopathological study of the excised specimen revealed the growth arising from an epidermal cyst. Malignant change is a rare, but wellknown complication occurring in an epidermal cyst. The mainstay of treatment consists of wide excision of cancerous lesion with primary reconstruction of the defect.

一名72岁男性患者，左臀区域出现一个巨大的溃疡增生性病变。经组织病理学确诊为鳞状细胞癌后，该病变被广泛切除。对切除标本的进一步组织病理学研究显示，肿瘤起源于表皮样囊肿。恶性变是表皮样囊肿中一种罕见但众所周知的并发症。治疗的主要方法是广泛切除癌性病变并对缺损进行一期修复。
