Pathology (Joe) Flashcards
Pathology (Joe)
Degeneration:
Calcification
Metastatic = Ca++ into normal tissue
Hypervitaminosis D
Dystrophic = Ca++ into abnormal/damaged tissue
Atherosclerosis, atheroma
Degeneration:
Caseous
cheesy
tuberculosis
Types of Degeneration
Albuminous
cloudy swelling
membrane injury, ion transfer fucked
Degeneration:
Coagulation
Infarction (MI)
Degeneration:
Enzymatic
Pancreas
(digests itself inside-out)
Degeneration:
Fatty
- *Liver = “nutmeg liver”** (reversible if caught early)
- *Heart = “tabby cat heart”** (stripes)
fatty dot → fatty streak → fatty plaque (atheroma) → fibroatheroma (fibrous tissue, calcium)
Degeneration:
Liquefactive
- *CNS**
- brain melts, tertiary syphilis, leprosy*
- *or skin**
- infection*
Degeneration:
Wallerian
peripheral nerves
degenerates to next Node of Ranvier
“dying back phenomenon”
Degeneration:
Zenker’s (Waxy)
hyaline cartilage
most common in skeletal muscle
(at epiphyseal plates)
muscle replaced with hyaline cartilage
Cellular Degeneration
Karyolysis: nuclear rupturing/fading/destruction
Karyorrhexis: nuclear swelling
Pyknosis: nuclear condensation
All the above = “nuclear dissolution”
leads to an anuclear necrotic cell
Developmental Changes
Agenesis: absence of organ (usually paired organs; renal, testicular.. odontoid)
Aplasia: small remnants of the organ, lack of development
Hypoplasia: smaller than normal, usually defective
Primary Pathology
vs
Secondary Pathology
Primary
- arrives spontaneously
- organ in question is fucked up
Secondary
- usually insidious
- resultant from other trauma/pathology
- organ in question is malfunctioning, due to some other organ not working properly
Growth Disturbances
Cancer
Metaplasia: functional change from one cell type to another
Dysplasia: change in size/shape/fx, precancerous, but last stage that can be returned to normal
- *Anaplasia:** complete disorganization of a cell (cancer)
- squamous cell carcinoma*
Collagen Types
Type 1
bone, muscle, tendons, ligaments
Type 2
disc (specifically nucleus pulposis)
- *Type 3**“reticular collagen”, spleen and lymph nodes
- *early wound healing**
Type 4
basement membrane of all tissues
Pneumoconiosis
Silicosis
silica from sand, rock, glass
Rocky QUarry disease
Pneumoconiosis
Asbestosis
asbestos
leads to mesothelioma
malignant tumor
Naval shipyard
Pneumoconiosis:
Siderosis
Iron dust particles
Iron Ore Mill/Steel Mill occupants
Pneumoconiosis:
Byssinosis
cotton dust
Brown Lung
Pneumoconiosis:
Anthracosis
Black Lung Disease from miners
Caplan’s Syndrome
(anthracosis + RA)
W.Virginia coal mines
Pneumoconiosis:
Histomycosis/Histoplasmosis
Endemic fungus
Mississippi/Ohio Valleys
“Mississippi Valley Fever”
“Ohio Valley Fever”
Pneumoconiosis:
Coccidiomycosis
Endemic fungus in deserts of SW USA
“San Joaquin Valley Fever”
(just Valley Fever in other states)
Pneumoconiosis:
Blastomycosis
Endemic fungus on Eastern seaboard
Florida to Nova Scotia
Asthma
Sputum analysis:
Curschmann’s Spirals
& Charcot-Leyden Crystals
↑IgE, ↑Eosinophils
(↑<em>IgE: wheezes, sneezes and weird ass diseases)</em>
Cystic Fibrosis
- Chloride channels affected
- “sweat test”
- mother notices, tastes salt = Salty Baby Syndrome
- Affects:
- GI mucous linings
- respiratory mucous linings
- exocrine secretions
- Susceptible to pseudomonas aeruginosa
- frequently requires lung transplants
Hemosiderosis
iron in lungs due to bleeding
rib fracture
pulmonary embolism (?)
stab/gunshot wound
Pulmonary Fibrosis
honeycomb lung
Tuberculosis
caseous necrosis in lung
Gohn complex, granulomas, epithelioid histiocytes
If spread to spine = “Pott’s Disease”
(with fracture or collapse of VB = Gibbus deformity)
Wegner’s Granulomatosis
Vasculitis of lung and kidney arteries
any system can be affected (polyangitis)
Emphysema
Alpha-1-antitrypsin (A1AT) deficiency = loss of elasticity
can’t breathe out
Azotemia
decreased tubular excretion of nitrogen
↑nitrogen in the blood
Hydronephrosis
most commonly caused by prostate problems/ureter stones
Kidney Stones
“Nephrolithiasis”
acute nephritic shock:
mc stone: calcium oxalate/ Ca++ urate
pain pattern: constant LBP, radiates to flank
localized groin pain = stone in ureters
painful voiding, pink urine
Dx: Murphy’s Punch
Nephritic Syndrome
RBCs and minor amount of protein in urine
(hematuria, mild proteinuria)
acute glomerulonephritis
Nephrotic Syndrome
- *“Pre-eclampsia”**
- *“HEP”: H_ypertension / _E**dema / massive Proteinuria
Eclampsia
HEP + seizure/convulsions+ coma
(potentially fatal)
Polycystic Kidney
multiple cysts on kidneys
moth-eaten appearance
idiopathic
Renal Shock
acute tubular necrosis
Wilm’s Disease
“nephroblastoma”
mixed (palpable) tumor of kidney in children
(if kids experience LBP = no bueno)
*mc malignant tumor found in kids
Addison’s Disease
↓cortisol, ↓BP
hypoadrenia/adrenal fatigue
inadequate cortisol levels = ↑↑ACTH to stimulate cortisol release
↑↑ACTH leads to ↑MSH
↑Melanocyte Stimulating Hormone = hyperpigmentation
fatigue
Cushing’s Disease
↑cortisol (z. fasciculata)
hyperadrenia
moon faces, buffalo hump, purple striae, central obesity
hypertension, water retention
<i>(opposite of Addison’s Disease)</i>
Conn’s Disease
↑↑Aldosterone (z. glomerulosa)
↑↑ADH = water retention
hypertension
Goiter
hyperplasia of thyroid cells due to lack of iodine

Cryptorchism
undescended testes
can cause testicular cancer
Endometriosis
mc site: ovary
<em>(endometrial cells should only be in uterus or outside body)</em>
