Gangliocytomas are rare and benign neuronal cell tumors, mostly found in the hypothalamic and sellar regions. Their histogenesis is still the subject of discussions. Herein we present a unique case of a pituitary gangliocytoma associated with a prolactinoma and a corticotroph adenoma in a patient affected by MEN1. The histologic study revealed shared features between adenomatous and neuronal cells, supporting the etiological hypothesis of a common origin or a phenomenon of transdifferentiation. Furthermore, gangliocytoma could be a new tumor related to MEN1. The clinical and histologic observations are discussed and the literature on the topic is reviewed.
神经节细胞瘤是一种罕见的良性神经元细胞肿瘤，多见于下丘脑和鞍区。其组织发生仍是讨论的主题。在此，我们报告一例患有多发性内分泌腺瘤1型（MEN1）的患者，其垂体神经节细胞瘤与泌乳素瘤和促肾上腺皮质激素腺瘤相关。组织学研究揭示了腺瘤细胞和神经元细胞之间的共同特征，支持了共同起源或转分化现象的病因学假说。此外，神经节细胞瘤可能是一种与MEN1相关的新肿瘤。本文讨论了临床和组织学观察结果，并对该主题的文献进行了综述。
