What Is The Difference Between Neurofibromatosis1 And Neurofibromatosis 2
Etiology: Nf 1 also called von recklinhausen, caused by single gene disorder on chromosome 17 and causes non cancerous lumps. Nf 2 also called central neurofibromatosis caused by mutation of merlin in chromosome 22q12. 10% of all nf and causes bilateral acoustic tumors. ...Read moreSee 3 more doctor answers
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Different cancers: Sarcomas are very rare cancers that arise from bone, muscle, nerves, blood vessels or other connective tissues. Carcinomas are very common cancers that tend form glands. Most common examples are breast cancer, lung cancer, colon cancer, prostate cancer and renal (kidney) cancer, among others. ...Read moreSee 1 more doctor answer
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
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
How they act: Malignant tumors can grow locally and destroy other tissues but can also spread distantly. Benign tumors can grow locally and can cause symptoms if they enlarge but do not spread to distant organs. Hope this helps. ...Read more
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
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. Osteochondromas usually need no treatment and are only followed, while osteosarcomas require agressive treatment, often including chemotherapy, radiation therapy and surgery; the prognosis has improved a great deal recently. ...Read moreSee 1 more doctor answer
Different origin: Hepatic adenoma is an uncommon benign liver tumor that is hormone induced most resulting from oral contraceptive use. . These tumours are usually solitary, arise from the hepatocytes, can convert to malignancy and have a tendency to hemorrhage. When multiple the condition is known as hepatic adenomatosis .Hemangiomas of liver are purely vascular lesions derived from hepatic blood supply ...Read more
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
"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 moreSee 2 more doctor answers
