CWP
Most common pneumoconiosis associated with TB
Silicosis
Pneumoconiosis with least risk of developing lung cancer
CWP
Pneumoconiosis affecting Lower lung
Asbestosis
Pneumoconiosis affecting Lower lung
Silicosis
CWP
Berylliosis
Caplans syndrome
Rheumatoid arthiritis nodules ( in upper lung ) + pneumoconiosis ( mostly silicosis )
Most common type of lung cancer caused by pneumoconiosis
Non small cell carcinoma
( Adenocarcinoma)
Most common lung cancer caused in Asbestosis
Bronchogenic Cancer
Diagnosis of Silicosis
ACUTE :
Hilar LNAP
BAL- milky fluid , PAS + flocculent densities
HRCT - Crazy pavement appearance
Ground glass opacities with interstitial septal thickening along with interspersed normal areas
CHRONIC :
CXR- Egg shell calcification in upper lung (<1cm nodules )
- conglomerate masses
Cause of productive cough in acute silico proteinosis
Secondary alveolar proteinosis
Due to collection of Surfactants as a result decreased macrophage action ( because of exposure to silica dust )
Silica reaction
Formation of calcified fibrotic nodule in lung parenchyma which causes inflammatory reaction leading to PMF in later stages
Silicosis increases risk of
TB
COPD
LUNG CANCER
COR PULMONALE
CAPLANS SYNDROME
Erasmus syndrome
Systemic sclerosis after exposure to SILICA
Comet tail sign
HRCT finding
Seen in Rounded atelectasis / folded lung syndrome / Blesovsky syndrome
Diffuse pleural thickening pulls bronchoalveolar bundles thus producing sign
Rare complication of Asbestosis
Intense pleural reaction causing folding of lung and pleura
Virus ass with mesothelioma
Simian virus 40
IOC for Asbestosis
Thoracoscopy guided biopsy
Most specific cancer in Asbestosis
Mesothelioma
Most common lung cancer in Asbestosis
Non small cell lung cancer ( adenocarcinoma)
Ferrugineous bodies or asbestos bodies , other name
Asbestos fibres covered with FERRITIN
Golden beaded appearance on HPE
