[Intracerebral gangliocytoma: a histological and immunohistochemical study]

We present a case of cerebral gangliocytoma placed on the right frontal lobe in a young adult, analyzing its morphological and clinical features. The immunohistochemical study defines it as a tumor with a neuronal population NSE and NFP positive, and a glial population with positivity for the GFAP. We emphasize the presence of neurosecretion in the mature neurones, typified by the positivity to the sinaptophisine and VIP. In the discussion we compare our immunohistochemical results, analyzing the histogenesis of this rare neoplasm.
