Oval Fat Bodies Diagram. These fat droplets consist of triglycerides neutral fat and cholesterol. Oval fat bodies in urine oval fat bodies in urine with polarized light transitional epithelial cells from the renal pelvis ureter or bladder have more regular cell borders larger nuclei and smaller overall size than squamous epithelium.
Lipids may also appear in the urine as free fat droplets fig. Under polarized light oval fat bodies demonstrate the maltese cross appearance. To facilitate the breakdown of fat and protein ingested through the food we consume.
The intracellular lipids coalesce into refractile globules within the tubular cells forming what are called oval fat bodies figure 4.
They are an infrequent finding and always abnormal occurring in the same tubular diseases as fatty casts. Fat stain will stain triglycerides and neutral. The oval fat body contains only a few fat droplets thus having a smaller size than other fat bodies 500x figure 165. Free body diagrams have been used in examples throughout this chapter.
