ABSTRACT
Objective To investigate the pathologic features of ganglioglioma/gangliocytoma.Methods 19 cases of gangliogliomas and gangliocytomas were studied by HE stain, immunohistochemistry and ultrastructural observation.Results (1) The tumor cells presented widespread, derangement distribution, and conglobation in some regions. (2) The tumor cells were similar with ganglion cell, showing multipolar in feature, and had large, irregular nucleoli. The nucleoli were clear. Some tumor cells were bi-nucleated. (3) Neurogliocytomas were Ⅱ~Ⅲ grades according to the standard published by WHO. (4) Immunoreactions showed GFAP (-), S-100 (+) and Synaptophyein (+) in neoplastic cells. (5) Ultrastructure observation showed cytolysosome, ribosome and rough endoplasmic reticulum in the cytoplasm of the neoplastic cells. Abundant mitochondria and dense neuroendocrine granules were also found in these cells.Conclusions Ganglioglioma/gangliocytoma is a rare tumor of central nervous system. Its diagnosis mainly depends on histopathology, special markers of immunohistochemistry and ultrastructural features. The property of neoplasma is related to the component of neurogliocytoma.
