Ferruginous body is a histopathologic finding in lung pathology that strongly suggests exposure to asbestos.
- Uncommon finding.
- Strongly suggestive of asbestos exposure.
Conditions associated with asbestos exposure (mnemonic PALM):
- Segmented twirling baton-like structure (approximately 3-5 micrometres x 20-80 micrometres) with long slender fibre within.
- Black/brown crystal-like appearance.
- Dirt - especially on H&E.
- Prussian blue stain +ve.
Comment: No cell block is available for further work-up, e.g. iron staining. The findings herein should be correlated with imaging and the clinical history. Ferruginous bodies are associated asbestos exposure.
