| Fatty Cast A fourth type of cast is the fatty cast. Fatty casts are clear cylinders containing droplets of fat which are highly refractile. These casts originate from the breakdown of the tubular epithelium containing oval fat bodies. Fatty casts are characteristic of degenerative tubular disease and are frequently seen with heavy proteinuria. | View Page |
| Cholesterol Crystals Cholesterol crystals may be seen in renal tubular disease. These crystals look like plates of glass, sometimes with a notch out of one corner. Under polarized light, they exhibit a stained glass effect. These crystals are rarely seen unless the specimen has been refrigerated, because the lipids remain in droplet form. Large amounts of protein, lipid droplets, fatty casts or oval fat bodies should be found along with cholesterol crystals. Cholesterol crystals are found in acid or neutral urine. | View Page |
