Title: Application of immunohistochemistry and electron microscopy in difficultly-diagnosed tumors in nervous system: 4 cases' report
Abstract: Objective To analyze and evaluate the application of immunohistochemistry and electron microscopy in difficultly-diagnosed tumors in nervous system.Methods Four cases of nervous system tumors were studied with immunohistochemistry and electron microscopy. Antibodies used in immunohistochemistry included those essentially and frequently used antibodies in diagnosis of nervous system tumors.Results Based on microscopic observation of the Hematoxylin-Eosin staining slides and immunohistochemistry and electron microscopy results, we diagnosed the 4 cases as: supratentorial primitive neuroectodermal tumor (PNET), desmoplastic infantile astrocytoma(DIA), chordoid meningioma and neurofibroma, in accordance with WHO nervous system tumor classification in 2000. Conclusion Application of immunohistochemistry and electronmicroscopy in the diagnosis of difficultly- diagnosed tumors in nervous system is very important.
