Hyalinizing Granuloma: An Unusual Case of a Pulmonary Mass
Figure 2
(a) Marked changes in lung architecture determinated by deposition of hyaline tissue masses accompanied by sparse lymphocytic infiltrate that compresses and distorts the remaining bronchioles (hematoxilin-eosin stain; original magnification, x40). A higher magnification (b) demonstrates that the mass is composed by hypocellular collagen lamellae (hematoxilin-eosin stain; original magnification, x100).
