|
| Undifferentiated type |
This type includes undifferentiated type and poorly differentiated type in INPC, and neuropils are not found at all or scanty. |
| Differentiating type |
This type is equivalent to the differentiating type in INPC. Neuropil is present. |
| Ganglioneuroblastoma(stroma-rich tumors) |
This tumor occupies more than 50% stoma consist of mainly Schwannian cells. |
| Intermixed type |
This tumor is equivalent to the GNB, intermixed in INPC. |
| Nodular type |
This tumor is equivalent to the GNB, nodular in INPC. |
| Well differentiated type |
This tumor is equivalent to the GN, maturing in INPC. |
| Ganglioneuroma (stroma-rich tumors) |
This tumor is equivalent to the GN, mature in INPC. |
