*Brown pigmented airspace macrophages - ''smoker's macrophages''. | |||
*Inflammation of the terminal bronchioles. | |||
Note: | |||

==Desquamative interstitial pneumonia== | |||
*Abbreviated ''DIP''. | |||
===General=== | |||
*Thought to be advanced ''[[RBILD]]''. | |||

Features: | |||
*Brown pigmented airspace macrophages - ''smoker's macrophages''. | |||
*Architecture preserved; "linear fibrosis". | |||
Notes: | |||
*Some fields of view may be indistinguishable from RBILD. | |||
*Amiodarone toxicity, fibrotic NSIP - may appear similar. | |||
