White blood cell cast in which leukocytes are intact and easily identified as having multilobed nuclei. In some areas, hyaline matrix can still be seen and is not obscured by heavy concentration of PMNs

Red blood cell and hemoglobin cast. Erythrocytes have degenerated, resulting in granular, yellowish brown hemoglobin in the cast matrix. However, numerous intact erythrocytes are still present and easily identifiable on the surface

Fatty cast. Lipid globules are prominent on its surface, but some uninvolved surface areas can also be seen underlying the lipids. Some lipid globules are also adjacent to the cast

Typical fatty cast in urine. Entire surface seems to comprise lipid globules of variable sizes. In the background, are several red cells and considerable cellular debris

Waxy cast, typified by “broken-off” ends and parallel serrated margins. Its brittleness is apparent, as it appears to be “splitting”
