- Neuroblastic tumors may be grouped according to International Neuroblastoma Pathology Classification (Shimada classification) into two groups: schwannian stroma rich group and a schwannian stroma poor group as illustrated below:[1]
Neuroblastic tumors | |||||||||||||||||||||||||||||
| Schwannian stroma rich group | Schwannian stroma poor group | ||||||||||||||||||||||||||||
Undifferentiated neuroblastoma Poorly differentiated neuroblastoma Differentiating neuroblastoma |
Nodular ganglioneuroblastoma Intermixed ganglioneuroblastoma Maturing ganglioneuroma Mature ganglioneuroma | ||||||||||||||||||||||||||||
- Based on the degree of cellular maturity and composition neuroblastoma may be further classified into three subtypes according to the International Neuroblastoma Pathology Classification which include:
- Undifferentiated neruoblastoma
- Poorly differentiated neuroblastoma
- Differentiating neuroblastoma
- The table below summarizes the differnces between the three histological subtypes of neurublastoma:
| Risk Factor | Description |
|---|---|
| Undifferentiated neruoblastoma | Completely formed by neuroblasts with no maturity of ganglion cells |
| Poorly differentiated neuroblastoma | Mostly formed by neuroblasts with less the 5% maturing ganglion cells |
| Differentiating neuroblastoma |
Predominantly formed by neuroblasts but with more than 5% mature ganglion cells |
