GNB - Nodular / composite

Tumor in this category is composed of at least 2 morphologcally distinct components: One component has an appearance of either Ganglioneuroblastoma, Intermixed or Ganglioneuroma and the other has an appearance of Neruoblastoma.
Proportion of these components varies depending on the time of surgery. Ganglioneuroblastoma, Intermixed/Ganglioneuroma component grows slowly or even stops growing at its fully mature status. In contrast, Neuroblastoma component keeps growing and even predominates the tumor tissue in the later stage of development of this tumor.
