anonymous Central neurocytoma (90%) Ependymoma(10%) Immunostain for Synaptophysin and Glial fibrillary acidic protein will resolve the problem. The uniform round nuclei, with fine stippled chromatin, occasional small nucleoli and eccentric nuclei all speak for central neurocytoma.  100

anonymous Central neurocytoma (90%); Ependymoma, cellular variant (10%). The age of the patient favours the diagnosis of a central neurocytoma. To be confirmed by immunostain for synaptophysin (positive in central neurocytoma).  100

anonymous central neurocytoma 80% ependymoma 20% Central neurocytoma is immunoreactive for synaptophysin but not for GFAP, which distinguish it from ependymoma.  100
