Summary
Pulmonary alveolar microlithiasis (PAM) is a rare lung disease. This report details the first Korean case of PAM in a young man, diagnosed via biopsy after imaging revealed lung abnormalities.
Area of Science:
- Pulmonology
- Radiology
- Pathology
Background:
- Pulmonary alveolar microlithiasis (PAM) is a rare interstitial lung disease of unknown cause.
- Characterized by diffuse, microscopic calcium deposits (microlithiasis) within the lung alveoli.
- Over half of patients are asymptomatic at diagnosis.
Observation:
- A 19-year-old male Korean patient presented with asymptomatic interstitial thickening on chest radiograph.
- High-resolution CT scan revealed diffuse, ill-defined micronodules and interstitial thickening.
- Open lung biopsy confirmed the diagnosis of Pulmonary alveolar microlithiasis.
Findings:
- The case represents the first documented instance of PAM in Korea.
- The patient remained asymptomatic throughout the diagnostic process.
- No disease progression was observed during a 6-month follow-up period without treatment.
Implications:
- Highlights the importance of imaging in diagnosing rare lung conditions like PAM.
- Suggests that asymptomatic PAM may exhibit a stable clinical course initially.
- Contributes to the understanding of PAM's geographical distribution and clinical presentation.

01:23Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
01:28Pulmonary Tuberculosis II
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
01:20Chronic Obstructive Pulmonary Disease-II: Pathophysiology
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

01:10Atelectasis II: Pathophysiology
Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through collapsed...
01:26Alveoli and Alveolar Ducts
The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...
