Diffuse Interstitial Fibrosis
Show a thickened interstitium next to a more normal thickness interstitium? Is this a non-specific finding in many chronic lung disease states? Name some common things which this might be associated...
Bronchopneumonia
What is the main differentiation between bronchopneumonia and lobar pneumonia? Where do broncho-pneumonias start? Why might this lung be heavier than normal? Why might there be fewer air bubbles when...
Lung - Acute Infarct - Septic
Why are true infarcts of the lung uncommon even with pulmonary emboli? Why might this one be called septic? Can you see bacteria?[if] Why might this be called a hemorrhagic infarct (rather than anemic...

Liver - Cirrhosis 1
What TWO features are ALWAYS needed to diagnose all types cirrhosis? Demonstrate each one.
Acute And Chronic Cholangitis
Which parts of the cut sections of the liver show the inflammatory changes? What is the usual cause of cholangitis? Why might this be called acute and chronic from a histopathological point of view?...
Diffuse Cortical Necrosis

Demonstrate tubules with hydropic change. What is hydropic change? Is hydropic change a NON-specific finding in many diseases?
Myocardial Infarction - Recent
Demonstrate granulation tissue. What is granulation tissue? Can the term granulation tissue be used, more or less, interchangeably, with the term organizing inflammation?
Myocardial Infarct - Remote
Draw a line separating the fibrosis (scar) from the normal cardiac muscle tissue. How might one differentiate scar (fibrosis), from coagulation necrosis, from normal cardiac muscle (in words)?
Myocardial Infarct
Demonstrate the coagulation necrosis. Demonstrate the neutrophilic infiltrates (i.e., acute inflammatory infiltrate)
Acute Fibrinous Pericarditis
Demonstrate the fibrin. Is it limited to the pericardial layer? What are some common causes of acute pericarditis?
