Abstract
|
|
|
Among the pneumoconiosis, the silicosis is an occupational lung disease, ordinally due to prolonged inhalation of air containing free silicon dioxide.
We had chanced to perform autopsy of three cases of silicotuberculosis. Both lungs with hard and contracted appearance, were showed massive fibrous adhesion to pleura and also revealed fritty appearance on cut sectioning, and the cut surfaces were shown dark greenish to black pigmentation.
Characteristically, many dense black or grey colored silicotic nodules mesuring upto 1-4㎜ in diameter, with anthracotic pigments were distributed throughout both lung parenchyma especially along the peribronchial regions in all three cases, commonly.
Microscopically, the nodules were noted as the mass of concentrically laminated dense fibrotic tissue, In addition to those findings, the pulmonary perenchmas were replaced by wide areas of fibrosis and also accompained with exudative and productive form of tuberculosis(common in all three cases), bronchopneumonia(except case-1) and also compensation emphysema, atelectatic lesions.
At the peripheral areas of the silicotic nodules, focal accumulation of the plasma cells, lymphocytes and many foci of endarteritis were shown in three cases, commonly.
The silica was confirmed by polarizing microscopy as birefringent, white colored crystals.
