Pathology of Pneumonia
1. Pneumonia

……..
I have no concerns that this group of students are in any way
resting on their laurels. So far the feedback from the medical staff
has been excellent. There have been a number of preceptors who
have noted the substantial difference between this years 4th yrs and
last years 4th yrs. A number of their preceptors in the hospital, who
are not easily impressed, have gone out of their way to tell me how
impressed they have been with this group.
…………
Impressive….! Keep it up…..!

42. Pneumonia
Bronchopneumonia (patchy)
Extremes of age. (infancy and old age)
Secondary to Risk factors.
Staph, Strep, Pneumo & H. influenza
Patchy consolidation – not limited to lobes.
Suppurative inflammation
Usually bilateral
More in Lower lobes

48. Pneumonia
Interstitial / atypical Pneumonia
Primary atypical pneumonia in the
immunocompetant host (Mycoplasma or
Chlamydia)
Interstitial pneumonitis
immunocompromised host : Pneumocystic carinii; CMV
Immunocompetant host: Influenza A
Gross features:
Lungs are heavy but not firmly consolidated
Microscopic features:
Septal mononuclear infiltrate
Alveolar air spaces either ‘empty’ or filled with
proteinaceous fluid with few or no inflammatory cells

Interstitial Pneumonia:
Lymphocyte
Infiltrate in

Pathology - Core Learning Issues:
Pathology of pneumonia and the course of pathological changes.
Different diagnostic modalities in the diagnosis of pneumonia
(chest x-ray, blood gases, sputum culture, bronchial washings,
serology)
Histopathology of pneumonia – Lobar, Broncho.
Complications of pneumonia, ARDS, effusions, empyema etc.,.
Basic science - Core Learning Issues:
Anatomy of the lobes of the lung. Why does aspiration occur on
right side?
Spread of infectious disease - mechanisms
Physiology of Respiration, Blood gases and Pulse Oxymetry.
Metabolic and respiratory acidosis.
Importance of oxygenation and oxygen delivery
Common respiratory pathogens

69. Pneumonia
Peter is 58 years old and is a non-smoker and he suffers aspiration of
gastric contents during cardiac resuscitation. Over the next 10 days he
develops a non-productive cough & fever. A chest radiograph reveals a 4
cm diameter mass with an air-fluid level in the right lung. A sputum gram
stain reveals mixed flora.
Of the following conditions which is he most likely to have?
1. Lobar pneumonia
2. Broncho pneumonia
3. Interstitial pneumonia

arterial hypertension for 5 years
urinary tract infection 1 month previously, which
was treated with ciprofloxacin 200 mg three-times
daily for 5 days
Patient has smoked 20 cigarettes/day for

Examination
Clinical findings:
awake
deteriorated clinical state
dyspnoea during rest (32 breaths/min)
rales (abnormal respiratory sound) over the
left lung
prolonged exhalation

Additional investigations
Chest X-ray is requested by the GP
X-ray shows a large infiltration in the
left upper and lower lobe of the lung,
suggestive of pneumonia

Patient is admitted to hospital on the
basis of his clinical and X-ray
findings, together with his smoking
history
