Summary
A cerebral neoplasm containing a well differentiated epidermoid cyst surrounded by islands of infiltrating squamous cell carcinoma and a pleomorphic spindle cell stroma was described. By immunoperoxidase staining all these components contained keratin. The lesion was therefore similar to malignant squamous cell lesions with sarcoma-like stroma occurring in other body sites.
