Pathology Note: Path/o = disease - logy = process of study |
The study of disease |
|
What is the disease process of pathology? |
Any Abnormal change within the body; bodies response to injury |
|
Etiology Note: Eti/o = cause -logy = process of study |
Study of disease causes |
|
Inflammation |
Initial response of body tissue to local injury |
|
Hyperemia Note: Hyper= above, excessive |
Heat & Redness associated with inflammation |
|
Exudate |
Plasma in tissue producing SWELLING |
|
Phagocytosis Note: Phag/o= eat, swallow - cytosis = condition of cells; slight increase in number. |
The process of W.B.C enzymatically digesting: infecting organisms & cellular debris |
|
Scar tissue |
Replacement of DEAD TISSUE with granulation tissue Ex: Fibrous tissue, adhesions, Keloid. |
|
5 signs of inflammation |
1. Rubor (redness) 2. Calor (heat) 3. Tumor (swelling) 4. Dolor (pain) 5. Loss of function |
|
Toxins Note: tox/o = poison |
Produced by BACTERIA Damages tissue, creates inflammation |
|
Pus Note: py/o, purul/o |
Yellow fluid produced by PRYOgenic bacteria |
|
Abscess |
Localized, Encapsulated, Collection of pus |
|
Bacteremia Note: Bacter = bacteria - emia = blood condition |
Bacteria in BLOOD (Blood poisoning, sepsis) |
|
Granuloma Note: Granul/o = granule(s) -oma = tumor; mass; fluid collection |
Localized area of chronic inflammation, often w/ CENTRAL NECROSIS Necrosis = dead area |
|
Edema Note: -edma = swell |
Accumulation of abnormal amounts: of fluid in the INTERCELLULAR TISSUE spaces of body cavities |
|
Anasarca Note: ana- = up; apart; backward; a new Sarc/o = flesh (connective tissue) |
Swelling of: SUBCUTANEOUS TISSUE throughout the body (Generalized edema) |
|
Ischemia Note: Isch/o = hold back; back -emia = blood condition |
Interference of: BLOOD SUPPLY to organ/ part of organ |
|
Collateral Vessels Note: Coll/a = glue |
Newly developed: blood supply |
|
Infarct Note: In- = in, into |
Localized area of: ISCHEMIC NECROSIS produced by occlusion of ARTERIAL SUPPLY/ VENOUS DRAINAGE. Necrosis= death of tissue |
|
Gangrene |
Tissue nercrosis |
|
Hemorrhage Note: Hem/o = blood -rrhage = burst forth (of blood) |
Rupture of blood vessel |
|
Hematoma |
Accumulation of: BLOOD within body tissue |
|
Atrophy |
Reduction in the: SIZE or NUMBER of cells |
|
Hypertrophy Note: Hyper- = above; excessive -trophy = nourishment; development (condition of) |
Increase in: CELL SIZE |
|
Hyperplasia Note: - plasia = development; formation; growth |
Increase in: NUMBER of CELLS |
|
Dysplasia Note: dys- = bad; painful; difficult; abnormal - plasia = development; formation; growth |
Loss of: NORMAL CELL UNIFORMITY |
|
Neoplasia Note: Neo- = New- plasia = development; formation; growth |
"New Growth": ABNORMAL PROLIFERATION of cells, tumor |
|
Oncology Note: -logy = process of study |
Study of NEOPLASMS |
|
Benign |
Closely resemble: CELLS OF ORIGIN, remain localization |
|
MaligNant Note: Mal- bad |
Neoplasms that: INVADE & DESTROY adjacent structures; metastasize "CANCED" |
|
-oma |
Suffix added to: CELL TYPE from which tumor originates |
|
Carcinoma Note: Carcin/o = Cancerous; cancer - oma = CELL TYPE from which tumor originates |
Malignant neoplasms originating from EPITHELIAL CELLS |
|
Sarcoma Note: Sarc/o = Flesh (connective tissue) -oma = CELL TYPE from which tumor originates |
Malignant tumors in: CONNECTIVE TISSUE Ex: (bone, muscle, cartilage) |
|
Seeding |
Diffuse: SPREAD of cancer |
|
Give 2 examples of SEEDING? |
1. Lymphatic spread 2. Hematogenous spread |
|
Grading |
Assesses: AGGRESSIVENESS/ degree of malignancy |
