Lab 3.c Asbestosis (glass slide 28-D7603)

Some of your glass slides show a carcinoma in addition to asbestosis. Remember that the risk of developing carcinoma of the lung is increased in persons with asbestosis, especially if they are also cigarette smokers.

Slides A & B

Slide A In this low power view, the airspaces appear irregular and the alveolar walls appear thickened. This thickening is due both to collapse of alveoli and to fibrous thickening of their walls.
Slide B At high power, look for asbestos bodies (also known as ferruginous bodies). These are fibers of asbestos that are coated with iron pigment.

*Questions:

1.How does the pattern of fibrosis in asbestosis differ from silicosis? 
2.What other malignant tumor is associated with asbestos, besides carcinoma of the lung?
