An endodermal sinus tumor in the cerebellopontine angle.


Immunohistochemical and ultrastructural findings in a primary intracranial endodermal sinus tumor are reported in this paper. The tumor cells exhibited AFP, CEA and anti-alpha-1-trypsin positive immunoreactivity immunocytochemically. Aggregates of electron-dense material in the extra- and intracellular spaces and amorphous basement membrane-like substance were seen extracellularly by electron microscopy. The clinicopathological, immunocytochemical and ultrastructural features were consistent with the criteria for primary intracranial sinus tumor.
