Abstract:
Objective:To investigate the clinicopathological and immunohistochemical features, histogenesis and biologic behaviors of choroids plexus tumors of the cerebellopontine(CP) angle. Methods:Four cases of choroids plexus tumors of the CP angle were studied by histopathological analysis, immunohistochemical staining and electron microscopic examination. The literatures were review emphasising the diagnostic criteria, differential diagnosis and histogenesis. Results:The histopathologic features of choroid plexus tumors of the CP angle were identical to that in the ventricular system. Immunohistochemical analysis showed that S-100, vimentin and CK of the tumor cells express positive. Choroid plexus papilloma expressed GFAP. The carcinoma of choroid plexus expressed CEA as well. Conclusion:Choroid plexus tumors arising in and occupying the CP angle are rare. The final diagnosis can be made by pathologic examination. The histogenesis may be the small choroid tuft protruding from the foramen of Luschka into the CP angle.
