Author: Mikael Häggström [note 1]

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.

Other pertinent findings

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.
