2. You will need to be able to identify and provide characteristics of the following microscope slides: Autolysis of the liver (cirrhosis) Tuberculosis (Ghon tubercle) Chronic gastritis Dissecting aneurysm Peptic ulcer Atherosclerosis Arteriosclerosis Lobar pneumonia Pulmonary emphysema Lung cancer Myocardial infarction Melanoma Diverticulosis Thrombus Diabetic Pancreas

4. Hyalinization of islet cells

6. Diverticulosis Small herniations (pouches) form in the gastrointestinal tract The mucosa (lining of the intestine) becomes thickened with epithelium cells

9. Aneurysm Fresh: Point of dissection Healed: Scar tissue

11. Autolysis of the Liver Disorganized intercellular material Granular appearance of cytoplasm Orange-peel look White spots within the cytoplasm Fat Clumping of nuclear material

12. Hint:

14. Atherosclerosis Foam cells Made up of lipids Cholesterol clefts

17. Lung Cancer Large nuclei Nuclear clumping Multiple nuclei Abnormal organelles Tar may be present

19. Thrombus Blood clot that occludes vessel Made up of platelets, clotting factors, red blood cells, white blood cells, fibers

21. Arteriosclerosis Calcium deposits in the tunica media and atheroma The calcium interrupts the elastic fibers of the media

23. Myocardial Infarction Cardiac cells have lost their striations Cytoplasm has shrunk creating space between cells Nuclei are no longer present White blood cells have moved into the area

25. Chronic Gastritis Intestinal metaplasia occurs (parietal cells and chief cells degenerate) Goblet cells are apparent White blood cells appear

27. Tuberculosis Ghon tubercle present Necrosed center (possibly calcified) Fibrous cap on the tubercle

28. Hint Slide

30. Pneumonia Alveoli are congested with white blood cells Fluid fills some of the alveoli

32. Emphysema Alveoli are extremely large Some alveoli are broken No white blood cells present

34. Melanoma Large nuclei Nuclear clumping Multiple nuclei Abnormal organelles Occurs in the melanocytes

36. Peptic Ulcer Erosion of normal tissue White blood cells present
