We report the case of a 56-year-old man who underwent removal of an intracranial epidermoid cyst 16 years ago. The cyst recurred 12 years later and was once again almost completely removed. A new recurrence 4 years later proved to be due to malignant change in the form of squamous cell carcinoma. Only 17 other cases of malignant change in an intracranial epidermoid cyst have been reported. Moreover, three other cases presented as primary intracranial squamous carcinoma.
我们报告了一例56岁男性患者的病例，该患者16年前接受了颅内表皮样囊肿切除术。囊肿在12年后复发，并再次几乎被完全切除。4年后新的复发被证实是由于鳞状细胞癌形式的恶性变。据报道，颅内表皮样囊肿发生恶性变的病例仅17例。此外，还有另外3例表现为原发性颅内鳞状细胞癌。
