Lungs

Contents
Tissue sampling
Fixation
Generally 10% neutral buffered formalin.
Presentations
Basic microscopic screening
- For screening of lung autopsies, see Lung autopsy
Mainly look for carcinoma. Further information: Lung tumor
If granulomas are seen, generally stain for acid-fast bacteria and fungi.
Common findings
Active searching for them is not mandatory.
Anthracosis (interstitial black material).
Respiratory epithelial shedding in a small bronchus. If present, look for vascular leakage, mucus hypersecretion and/or widespread airway narrowing, together indicating asthma.[1]
Other pertinent findings
Pulmonary aspergillosis, seen as acutely branching septated hyphae.[2]
Pulmonary mucormycosis, seen as non-septated and broad-branching, and sometimes branching at right angles (black arrow).[3]
For fungi not conforming to the two main forms above, a general pathologist may attempt to get input by readily available expertise locally, but if it cannot be readily speciated, then it's generally acceptable to simply report as fungi present.
