- SURROUNDING LUNG WITH MILD EMPHYSEMATOUS CHANGES. | |||

====Micro==== | |||
The sections show lung with a well circumscribed lesion with a fibrous capsule partially lined by respiratory-type epithelium. The lesion consists of abundant respiratory epithelium and glands with focal sheeting and small collections of neutrophils focally. Small foci of degenerative changes are seen. The epithelium of the lesion as a gland cytomorphology. Mitotic activity is not readily apparent. Fat is not identified as a component of the lesion. Around the periphery of the lesion pulmonary edema is present. | |||
The piece surrounding lung more distant from the lesion has mild emphysematous changes. No interstitial fibrosis is identified. No significant inflammation is present. The arteries are approximately the size of accompanying airway. The arteries have no appreciable intimal thickening. | |||
