Basic autopsy cutting
In non-forensic Autopsy:
- The lungs may be cut after removing the heart through cutting through the major vessels close to it, or by removing each lung by cuts by each lung hilum.
- Dissect the pulmonary arterial system, from the pulmonary trunk and including at least segmental arteries.
- Dissect the bronchial tree, at least to segmental bronchi. Check for obstructions.
- Weigh each lung (possibly first if having cut each lung at the hilus).
- Make some additional sections through the lung parenchyma. Squeeze at each side to detect any pus and edema.
- For context, see Autopsy
- A spongy consistency, and watery and frothy liquid being pressed from the parenchyma, indicates simple edema.
- A spongy consistency and reddish (blood-stained) fluid being pressed from the parenchyma, indicates acute congestion.
- A brownish or dark reddish color of the fluid pressed from the parenchyma indicates chronic congestion, and may not have a spongy consistency.
Generally 10% neutral buffered formalin.

- Alveolar fluid. Further information: Alveolar fluid
- Vascular congestion, which can usually be seen easiest in the alveolar walls. It indicates left sided heart failure, especially when seen together with alveolar fluid.
- Inflammatory cells, where a mild to moderate lymphocytic infiltrate is consistent with with heart failure, while neutrophils indicate pneumonia.
- Mycobacteria in regions of the world with substantial prevalence
- Carcinoma Further information: Lung tumor
- Aspiration: Other foreign contents in airways. Further information: Aspiration in autopsy
Carcinoma (in this case bronchioloalveolar cell adenocarcinoma) Further information: Lung tumor
- Left sided heart failure:
Additional potential findings are mentioned in the general Lungs article.
Report findings and if they are consistent with already known diagnoses.

- Objectively, siderophage-like cells would be reported as "brown pigment-containing macrophages", but can be presumed to be siderophages in this context.
