What is the difference between neuroblastoma and a neuroectodermal tumour?

What is the difference between neuroblastoma and a neuroectodermal tumour?

Many differences: They are both cancers and may both be derived from primitive neural tissue. Otherwise they can be easily distinguished by a pathologist using a series of special stains. These tests distinguish different cell types. Also these tumors display different genetic abnormalities. Bottom line, these tumors ate derived from very different cells. These tumors are also treated very differently. ...Read more

What is the difference between a sarcoma and mesothelioma?

What is the difference between glioblastoma and glioma?

GBM is agressive: Glioblastoma is a malignant tumor of the brain. It often invasive and agressive form of brain tumor whereas glioma is often a benign primary brain tumor. Glioblastoma has the tedency to spread locally or to other part of the brain. Treatment of glioblastoma includes combination of surgery, radiatoin with or without chemotherapy. Gliomas usually do not spread and are treated by resection alone. ...Read more

What is the difference between carcinoma and sarcoma?

Cell of origin: Both are malignancies. Carcinoma arises from the lining tissues- both on the outside (e.g. Skin) and inside(intestine). Sarcomas from the mesenchyme- the tissues inside the lining. ...Read more

What is the difference between maligant and a benign cancer?

What is the difference between maligant and a  benign cancer?

Overall course.: There are many differences between benign and malignant tumors. A benign tumor is often well differentiated, looks almost normal, and does not spread. A malignant lesion is usually poorly differentiated, ominous looking, and spreads to other sites by blood, lymphatics, and directly. It has a very bad course, and results many times in death unless aggressive treatment is done. ...Read more

What is the difference between cancer and a teratoma?

What is the difference between cancer and a teratoma?

CA & Teratoma: Teratoma is a tumor with more than one tissue or organ in it that are all normal, like teeth and hair. Tumor is just a mass or lump. CA is made up of cells that are no longer normal and that are rapidly dividing and growing. ...Read more

What is the difference between osteochondroma and osteosarcoma tumors?

Benign vs cancer: Osteochondromas are the most common form of non-cancerous bone tumors, usually look like they are growing on the bone surface, and do not spread beyond the affected bone. Osteogenic sarcomas are aggressive cancerous bone tumors that typically cause destruction of the involved bone as well as producing new bone in a haphazard fashion. ...Read more

What is the difference between hereditary and sporadic retinoblastoma?

What is the difference between hereditary and sporadic retinoblastoma?

Both are caused by : genetic defects. Hereditary Rb CAN be caused by a mutant gene inherited from one of the pt.'s parents,but each of the pt.s children WILL have a 50% risk of having Rb from inheriting the mutation. Sporadic Rb is caused by at least 2 mutations of the RB1 gene in the cells of one eye that are NOT passed on to the pt.'s children. ...Read more

What is the difference between osteosarcoma and osteochondroma?

Sarcs are malignant: Osteosarcoma is a cancer starting in bones, most commonly in children/young adults, while osteochondroma is a non-cancerous bony spur, most often occuring in teenagers.

What is the difference between malignant and benign cancers?

Cancer: There are benign tumors (grow but don't spread) and malignant tumors (grow and spread to other parts). These last ones are cancers. There is no such thing as a benign cancer even though some behave less aggressively than others. ...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 the difference between lipoma and phyllodes?

What the difference between lipoma and phyllodes?

"Apples and Oranges": A lipoma is a benign fatty tumor that is most commonly found just under the skin anywhere on the body. They may occasionally cause discomfort but are most often removed for cosmetic reasons. A phyllodes tumor is a type of breast tumor that resembles a fibroadenoma; though benign, it can be locally aggressive; therefore, it is best treated by wide excision w/clear margins. ...Read more
