<unk>  is characterized by localized changes in lung architecture determined by deposition of hyaline collagenous fibrosis accompanied by sparse lymphocytic infiltrate that compresses and distorts the remaining bronchioles. A higher magnification, the mass is composed by hypocellular collagen lamellae.
