what is tissue diagnosis?

Question

In the diagnosis for neuroblastoma, why should a tissue sample be taken?

Answer 1

Pathology: A "mass" can be anything including non-cancer. A piece of tissue from a mass (or bone marrow biopsy, or blood) placed on a glass slide for a pathologist to review with special stains and sometimes molecular tests can give a "tissue diagnosis". With very few exceptions (eg, hcc, germ cell cancer) oncologists require a "tissue diagnosis" before treating cancer.

Answer 2

Tissue diagnosis: Tissue diagnosis is the diagnosis rendered by a pathologist and is based upon the microscopic examination of a tissue specimen removed during a biopsy/surgical procedure.

Answer 3

Granulation Tissue?: Granulation tissue is a type of scar tissue which forms in wounds to allow for healing. It is composed of collagen, blood vessels, and immune cells that aid in healing. If excessive ("proud flesh") this may interfere with healing and require minor topical or surgical treatment.

Answer 4

Granulation Tissue: Granulation tissue is a beefy red wound bed that is rich in healing & immune defense factors. When wounds become infected and are opened for the infection to be physically removed, they are packed with wound care products that promote this tissue to grow and help in wound closure. The granulation tissue fights infection & contracts the wound shut over weeks - months depending on nutritional status.

Answer 5

Everything: Intravenous contrast helps show blood vessels, solid organs like the liver, and improves visualization of disease like tumors and infection.

Answer 6

Many: Organs: heart, lungs, larynx, esophagus, liver, kidney, pancreas, small intestine, hands, face, abdominal wall tissues: blood, skin, bone, cornea.

Answer 7

Porcine tissue graft: Porcine grafty is natural and will not erode but there is a higher rate of reoccurence of the problem fore which it is placed as it is natural tissue and not permanent mesh.

Answer 8

Higher failure rates: The use of porcine tissue in the repair of pelvic organ prolapse has been done for sometime now and many physicians, including myself, have seen higher failure rates than with permanent mesh. Complications associated with porcine grafts are similar to synthetic meshes except erosion or extrusion to the porcine graft tend to be less problematic depending on which product is used.

Answer 9

Normal finding: The thymus gland is found in your mediastinum, it is part of your immune system (it helps with the development of your t-cells). It is larger in youth and diminishes in size with age. This is not a finding that suggests a problem.
