	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 bland 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 sections show lung with a well circumscribed lesion with a fibrous capsule partially lined by respiratory-type epithelium.
