1. Respiratory Infections

10. Pathological description of pneumonia

16. Lobar pneumonia (upper lobe – grey hepatisation), terminal meningitis

17. Pneumonia – fibrinopurulent exudate in alveoli (grossly “red hepatisation”)

18. Pneumonia – neutrophil and macrophage exudate (grossly “grey hepatisation”)

20. Pneumonia – fibrous organisation

22. Bronchopneumonia

30. Immunosuppressed patient – fatal haemorrhage into Aspergillus-containing cavity

31. HIV-positive patient CMV (cytomegalovirus) and “pulmonary oedema” on transbronchial biopsy….

32. Special stain also shows Pneumocystis

43. Primary TB – Ghon Focus

45. Granulomatous inflammation with caseous necrosis

46. Acid fast stain – spot the organism (a red snapper)!

49. Secondary TB – rapid death due to miliary disease

50. Miliary white foci – blood spread to lower lobe

51. “ Galloping consumption” – TB bronchopneumonia

52. Decreased immunity – many more organisms on acid fast stain

59. Bronchiectasis with chronic suppuration

60. Bronchiectasis

61. Bronchiectasis distal to an obstructing tumour
