  1. Inflammation p.1 SYLLABUS: Robbinsand Cotran, PathologicBasis of Disease, Chapter: Acuteand ChronicInflammation(all)

  2. Inflammation p.1 103Lobar pneumonia 106Appendicitis 155 Nasal polyp • Pericarditis (fribrionous) • Follicular hyperplasia of the lymph node 119Candidiasis (esophagus)

  3. Lobar pneumonia • alveoli filled with fibrinous exsudate • (fibrin stain)

  4. Lobar pneumonia

  5. Lobar pneumonia

  6. Appendicitis • neutrophilic inflammatory infiltration of all the layers of appendix • possible mucosal ulcerations, inflammatory exsudate in the lumen of appendix, necrosis of the wall extending to serosa

  7. Appendicitis

  8. Appendicitis

  9. Appendicitis

  10. Nasal polyp • edematous mucosa with a loose stroma • often hyperplastic or cystic mucous glands • a variety of inflammatory cells, including neutrophils, eosinophils, and plasma cells with occasional clusters of lymphocytes

  11. Nasal polyp

  12. Nasal polyp

  13. Pericarditis (fibrinous inflammation) • fibrinous exsudate (eosinophilic meshwork of threads and amorphous masses) covering pericardium

  14. Pericarditis (fibrinous inflammation)

  15. Pericarditis (fibrinous inflammation)

  16. Follicular hyperplasia of the lymph node (Reactive lymphoid hyperplasia, follicular pattern) • increase in number and size of germinal centers, due to expansion of follicular center, occasionally of mantle as well • follicular polarization retained

  17. Follicular hyperplasia of the lymph node

  18. Follicular hyperplasia of the lymph node

  19. Candidiasis (esophagus) Organisms: a mixture of budding yeast forms (blastoconidia) and pseudohyphae, tubular structures separated by narrowed areas Tissue reaction: usually purulent but may be minimal or granulomatous

  20. Candidiasis (esophagus)

  21. Candidiasis (esophagus)
