A procedure done to remove tissue or cells from the body for examination under a microscope
BIOPSY
Type of biopsy used to remove very small pieces from a tumor.
FINE NEEDLE ASPIRATION BIOPSY
What molecules are studied in Molecular Pathology?
DNA, RNA and/or protein.
The specimen is put into a fluid called a fixative for several hours, depending on the specimen type
Permanent sections
It is the study of tissues removed from living patients during surgery to help diagnose a disease and determine a treatment plan.
SURGICAL PATHOLOGY
Type of biopsy done with a long, thin tube that has a close-focusing telescope on the end for viewing.
ENDOSCOPIC BIOPSY
Biopsy that involves taking a deeper sample of skin with a biopsy instrument that removes a short cylinder, or "apple core," of tissue.
PUNCH BIOPSY
What is the purpose of Molecular Pathology?
To diagnose disease and/or to guide the prevention and treatment of disease.
The specimen can be examined shortly after it has been removed from the patient
Frozen sections
It's a medical exam of a body after death.
AUTOPSY
This type of biopsy is often used when a wider or deeper portion of the tissue is needed
INSICIONAL OR EXCISIONAL BIOPSY
Biopsy that involves taking a small amount of tissue.
BONE MARROW BIOPSY
Specific changes to the composition of genes in molecules are knpwn as...
Mutations
These are done when the specimen is a liquid or there are small, solid chunks suspended in liquid.
Smears
It's the exam of a single cell type, as often found in fluid specimens.
CYTOLOGY
Type of biopsy when the entire tumor is removed.
EXCISIONAL BIOPSY
Where does the tissue is taken from in a Bone Marrow Biopsy?
The tissue is usually taken from the back of the hip bones
Rearrangements of large portions of DNA are known as...
Translocations
This is usually considered the "bottom line" in a biopsy report.
Diagnosis
What is Histology?
The exam of an entire block of tissue
Type of biopsy when only a portion of the tumor is removed.
INSICIONAL BIOPSY
What are shave biopsies used for?
To diagnose some basal cell or squamous cell skin cancers as well as other skin lesions.
What happens to the specimen after the biopsy is done?
it's processed as a histologic section or a smear
It describes how it looks to the naked eye and where the biopsy was taken from in a biopsy report.
Gross description
What is the purpose of Cytology?
It's mainly used to diagnose or screen for cancer. It's also used to screen for fetal abnormalities, for pap smears, to diagnose infectious organisms, and in other screening and diagnostic areas
