​Pathology - Atypical Pneumonia

​Pathology - Atypical  Pneumonia
Mycoplasma pneumonia; influenza, rhinovirus, and adenovirus infections: The organisms mentioned are Chlamydia psittaci and Coxiella burnetii. Legionella pneumophila
Lung: Frequently involving multiple lobes: characterized by scattered infiltration of mononuclear inflammatory exudate inside the walls of the alveoli; it is possible to observe pink hyaline membranes lining the alveoli.

Symptoms and signs 
Symptoms of malaise include fever and muscle aches. The clinical presentation of malaise, including occasional cough, is generally milder compared to bacterial pneumonias.
Imaging: Chest X-ray shows irregular areas of infiltration.
Laboratory results: Abnormally high white blood cell count. Increased amounts of cold agglutinins in Mycoplasma pneumoniae infection.

Therapy  
Treatment with antibiotics involves providing supportive care.
Pneumocystis carinii pneumonia (PCP) is the predominant opportunistic illness observed in individuals with AIDS. The condition has an interstitial pattern of lung disease and can be diagnosed with the use of a silver stain on a bronchial lavage sample.
Cryptogenic organizing pneumonia can occur following atypical pneumonias or exposure to toxins through inhalation. The patient exhibits symptoms such as weight loss, fever, cough, hypoxemia, and dyspnea. The chest X-ray reveals scattered infiltration that resembles atypical pneumonias. The treatment involves the administration of steroids or cyclophosphamide if steroids prove to be unsuccessful.
