Objective To explore the pathologic features, histological classification, prognosis and the main points of diagnosis of nodular ganglioneuroblastoma ( GNBn). 目的探讨结节型节细胞神经母细胞瘤(GNBn)的病理形态特征、组织分型、预后及诊断要点。
Ganglioneuroblastoma had inhomogeneous soft tissue density mass, frequently with necrosis and lymphadenopathy. 囊肿呈水样密度,壁薄光整,1例有囊壁钙化。神经节母细胞瘤为密度不均匀软组织肿块,内见坏死灶,伴周围淋巴结肿大。
It is key characteristic that a few NB can differentiate to ganglioneuroblastoma naturally. 少数NB能自然分化成神经节细胞瘤,这一自然退化过程是NB的重要特征。
