Two cases of primary intracranial squamous cell carcinomas are reported. The first patient is a 57-year-old man with an epidermoid carcinoma in the right cerebellopontine angle, having histological features that indicated malignant transformation in a benign epidermoid cyst. The second patient is a 42-year-old man in whom squamous cell carcinoma arose in a pre-existing middle fossa dermoid cyst 9 years after the initial surgical resection. The literature on primary intracranial squamous cell carcinomas is reviewed, and the clinical features and histological pathogenesis for the occurrence of this unique condition are discussed.
报告了2例原发性颅内鳞状细胞癌。首例患者为一名57岁男性，右侧桥小脑角有表皮样癌，其组织学特征表明良性表皮样囊肿发生了恶性转化。第二例患者为一名42岁男性，在初次手术切除9年后，中颅窝皮样囊肿发生了鳞状细胞癌。本文回顾了原发性颅内鳞状细胞癌的相关文献，并讨论了这种独特病症发生的临床特征和组织学发病机制。
