Hat is the difference between neuroblastoma and neuroectodermal tumor?

Hat is the difference between neuroblastoma and  neuroectodermal tumor?

Both are Embryonal: Both neuroectodermal (pnet) and neuroblastoma (nb) come from undifferentiated primitive cells and arise out of the cells that form the nervous system. Nb comes from cells that form the peripheral nervous system, while pnet tumors come from cells that participate in the making of the central nervous system. Thus, nb is found outside of the brain and spinal cord, while pnets are found within the cns. ...Read more

In everyday usage, we use "tumor" ...Read more

What is the difference between a neuroblastoma and a neuroectodermal tumor?

Somewhat similar: Neuroblastoma and primitive neuroectodermal tumros are somewhat related. The neuroblastoma is a type of cancer in children that arises from immature nerve tissue outside of the central nervous system. It usually occurs in the adrenal gland on top of the kidney, but it can be found anywhere along the spine. It is not a brain tumor and represents the most common solid tumor of childhood. Primitive neuroectodermal tumors (PNETs) are a group of highly malignant tumors composed of small round cells of neuroectodermal origin that affect soft tissue and bone ie Ewings sarcoma . ...Read more

What is the difference between neuroblastoma and a neuroectodermal tumour?

Cell type: Both are rumors that can arise in locations of normal nerve tissue. Cell types will differ for both types as will tumor behavior. Neuroblastoma is typically found in younger children under four years of age. The age range for pnet is broader. ...Read more

Can you tell me about neuroblastoma vs neuroectodermal tumour?

Different diseases: Neuroblastoma and neuroectodermal tumors are different diseases. Both can affect children of all ages and both are treated differently. Neuroblastoma specifically the 4-S variety can go away on its own without treatment. This can only be established by a biopsy and specific biologic tests. Please submit a more specific question. Hope everything is okay. ...Read more

PNET tumors: This is a family of uncommon tumors that can occur in several areas. They can occur in the neck, chest, peripheral area, and nervous systmethey tend to occur in young patients but not exclusively. They are also in the ewing family of tumors. These are aggressive tumors that are treated with good success when localized. When metastatic the prognosis is poor. ...Read more
