Crystals (gout) and blood cells in polarized light. (WC/Gabriel Caponetti)
Acquired cystic disease-associated renal cell carcinoma with non-polarized light and polarized light to highlight the oxylate crystals. H&E stain. (WC/Nephron)
Polarization, formally light polarization, in pathology refers to a technique used in light microscopy that makes use of polarized light.
Notable things that polarize
- Amyloid - apple-green birefringence.[1]
- Oxylate crystals - ethylene glycol poisoning,[2] acquired cystic disease-associated renal cell carcinoma, benign breast calcifications.[3]
- Gout crystals - negatively birefringent, yellow when aligned, needle-shaped.[4]
- Pseudogout crystals - positively birefringent, blue when aligned, rhomboid-shaped.[4]
Some other things that polarize
- Dirt.
- Collagen.
