原始神经外胚层肿瘤(PNET)是罕见的高度恶性小圆细胞肿瘤,可分为中枢型(cPNET)与外周型(pPNET)。两者除发病部位不同以外,在好发年龄、转移途径、免疫组化染色、染色体易位等方面也不同。因此需对两者进行鉴别,尤其是病灶邻近脑膜或位于椎管内时更有必要。对cPNET及pPNET的肿瘤遗传学、临床表现、病理诊断、影像表现、治疗和预后,以及cPNET与pPNET,cPENT与髓母细胞瘤,pPNET 与尤文氏肉瘤之间的关系等进行综述。
原始神經外胚層腫瘤(PNET)是罕見的高度噁性小圓細胞腫瘤,可分為中樞型(cPNET)與外週型(pPNET)。兩者除髮病部位不同以外,在好髮年齡、轉移途徑、免疫組化染色、染色體易位等方麵也不同。因此需對兩者進行鑒彆,尤其是病竈鄰近腦膜或位于椎管內時更有必要。對cPNET及pPNET的腫瘤遺傳學、臨床錶現、病理診斷、影像錶現、治療和預後,以及cPNET與pPNET,cPENT與髓母細胞瘤,pPNET 與尤文氏肉瘤之間的關繫等進行綜述。

Primitive neuroectodermal tumor is a rare and highly malignant small round cell tumor. It can be divided into central PNET (cPNET) and peripheral PNET (pPNET). In addition to the lesions’ location, however,they are different in predilection age, route of metastasis, immunohistochemical staining, and chromosome translocation. So it is very necessary to identify each other, especially, when the lesions are close to the meninges or located in the vertebral canal. The aim of this review was to investigate the tumor genetics, clinical manifestation, pathologic diagnosis, imaging findings, treatment, and prognosis of the two kinds of tumors, also investigate the relationships between cPNET and pPNET, cPENT and medulloblastoma, pPNET and Ewing’s sarcoma.
