62
SEC appearance
Thin, flat having “**flagstone**” appearance, distinct edges
Small, centrally located nucleus with small amount of cytoplasm (**fried egg** appearance)
Can also be anucleated.
Fine granulation in cytoplasm
63
transitional cells appearance
Centrally located nucleus
**Round** or **pear-shaped** with a dense oval-to-round nucleus
Abundant cytoplasm- nucleus to cytoplasm ratio is **1:5**
The peripheral borders of the nucleus and cytoplasm are distantly outlined.
64
RTE appearance
**Eccentrically** placed nucleus (not easily visible in unstained sediment)
Nucleus to cytoplasm ratio **1:1**
collecting duct: **cuboidal**, at least one straight edge
65
OFB appearance
Highly refractile due to absorbed lipids
Positively identified using polarized microscopy
**Maltese cross** formation
66
Trich appearance
Pear-shaped flagellate with undulating membrane
67
cast appearance
Cylindrical with parallel sides, vary in length and width
Ends may be round, blunt, or broken
68
amorphous urate appearance
Yellow-brown sand-like granules
Clumps or attached to other structures
Pink sediment (uroerythrin)
69
