Study Notes
Lung Cancers
- Squamous Cell Carcinoma: Centrally located in the lung, strongly associated with smoking. Can cavitate (form a cavity). Stains positive for keratin.
- Adenocarcinoma: More common in non-smokers. Often found peripherally in the lung. Often secretes PTHrp (parathyroid hormone-related peptide). May be associated with hypercoagulable state.
- Small Cell Carcinoma: Also central, strongly associated with smoking.
- Large Cell Carcinoma: A less common type of lung cancer.
Other Lung Conditions
- Mesothelioma: Cancer of mesothelial cells, linked to asbestos exposure. Often appears as a white encasing rind around the lungs producing a "pancoast tumor". May cause Horner's syndrome; miosis, ptosis, anhidrosis, and SVC syndrome (flushing of the face + congestion of neck veins) or brachiocephalic syndrome (only the right side of face/neck).
- Bronchogenic Carcinoid Tumor: A neuroendocrine tumor that can produce serotonin-like substances, causing carcinoid syndrome (tachycardia, flushing, diarrhea).
- Nasopharyngeal carcinoma: A type of squamous cell carcinoma of the airway, associated with EBV.
- Laryngeal Cancer: Squamous cell carcinoma of the vocal cords, strong smoking association. Spreads to cervical lymph nodes.
- Laryngeal Papillomatosis: Pediatric condition characterized by vocal cord warts, usually due to HPV infection.
- Pneumoconioses: A group of lung diseases caused by inhalation of inorganic dust particles.
- Asbestosis: Resulting from asbestos exposure, which may eventually lead to mesothelioma.
- Berylliosis: Resulting from beryllium exposure.
- Silicosis: Resulting from silica exposure, often in foundry workers.
- Anthracosis: Due to coal dust inhalation.
- Caplan Syndrome: Combination of rheumatoid arthritis and pneumoconiosis.
- Idiopathic Pulmonary Fibrosis (Usual Interstitial Pneumonitis): Restrictive lung disease characterized by reticular/reticulonodular pattern on CXR/CT.
- Chronic Obstructive Pulmonary Disease (COPD): Combination of chronic bronchitis (productive cough for 3+ months/year) and emphysema (destruction of alveoli). Associated with smoking. Emphysema can be pan-acinar or centri-acinar. A1-antitrypsin deficiency is a genetic link to emphysema.
- Chronic Bronchitis: Excessive mucus production in the bronchioles. Characterized by a "blue bloater" presentation.
- Emphysema: Loss of alveoli, leading to decreased lung elasticity. Characterized by "pink puffer" presentation.
- Asbestosis: Resulting from asbestos exposure. This may precede the development of mesothelioma.
- Important Note About COPD Exacerbations: A COPD exacerbation is often indicated by increased CO2 levels.
