=====Neurocytoma of the pituitary gland=====

Tumors with hypothalamic neuronal differentiation are classified as [[gangliocytoma]]s or [[neurocytoma]]s based on large and small cell sizes, respectively

====Case reports====
A 56-year-old male patient with [[bitemporal hemianopsia]]. Computed tomography and magnetic resonance imaging revealed a tumor in the sellar region. The tumor was totally excised. Postoperative histological examination of the tumor demonstrated that [[synaptophysin]], chromogranin-A and neuron-specific enolase were positive, while luteinizing hormone, follicle-stimulating hormone, growth hormone, prolactin, adrenocorticotropic hormone, thyroid-stimulating hormone, glial fibrillary acidic protein, S-100, nestin and epithelial membrane antigen were negative, which were the main pathological features of [[neurocytoma]]s. This is the fourth case of EVN located in the sellar region reported
