			==Sign out==
			<pre>
			Lung, Right Lower Lobe, Open Lung Biopsy:
			- Organizing pneumonia.
			- Emphysematous changes.
			- NEGATIVE for significant pulmonary fibrosis.
			- NEGATIVE for malignancy.

			Comment:
			There is no evidence of granulomatous disease.
			</pre>
			===Micro===
			Organizing pneumonia with well-formed Masson bodies is seen subpleural and peribronchial. It is pathcy and mild. Significant fibrosis is absent. Eosinophils are not readily apparent.

			'''Organizing pneumonia''', abbreviated '''OP''', is a histologic pattern in [[lung pathology]].

			==General==
			*Multiple causes, e.g. transplant rejection, infection.

			Clinical diagnoses:<ref name=Ref_WMSP91>{{Ref WMSP\|91}}</ref>
			*[[Lung transplant pathology\|Transplant rejection]].
			*Cryptogenic organizing pneumonia (COP), [[AKA]] (idiopathic) bronchiolitis obliterans organizing pneumonia (BOOP).
			**Should '''not''' be confused with ''[[constrictive bronchiolitis]]'' (AKA ''[[bronchiolitis obliterans]]'').
			*[[Collagen vascular disease]].
			*Toxic injury.
			*Infection.
			*Peri-tumor - in proximity to a space-occupying lesion (abscess, neoplasm).

			Note:
			*BOOP is used as a synonym for ''organizing pneumonia'' which has the long differential diagnosis above.<ref name=Ref_WMSP91>{{Ref WMSP\|91}}</ref>
			**Confusingly, it may be used to refer to the idiopathic form of organizing pneumonia, now generally known as ''cryptogenic organizing pneumonia'' (COP).
			***In other words, strictly speaking, ''BOOP'' is '''not''' the same as ''COP''; idiopathic BOOP ''is'' COP.

			==Microscopic==
			Features:<ref name=Ref_Klatt110>{{Ref Klatt\|110}}</ref>
			*Distal airway disease -- airways plugged with organizing exudate ("[[Masson bodies]]").
			**"Organized exudate" = fluffy light-staining paucicellular regions with stellate cells (fibroblasts & immature connective tissue).
			*'''No''' hobnailing of pneumocytes.
			**Type 2 pneumocytes hyperplasia is absent.

			DDx:
			*[[Diffuse alveolar damage]], proliferative phase - has type 2 pneumoncyte hyperplasia.
			*[[Bronchiolitis obliterans]].
