Howell-Jelly Body
- They are histopathological findings of basophilic nuclear remnants(smooth,round remnants) (clusters of DNA) in circulating erythrocytes.
- Usually, only one per cell is seen but, occasionally, there may be more than one in some cases.
- During maturation in the bone marrow late erythroblasts normally expel their nuclei, but in some cases a small portion of DNA remains.
- Its presence usually signifies a damaged or absent spleen because a healthy spleen would normally filter this type of red blood cell.
- Howell–Jolly bodies are also seen in: amyloidosis, severe hemolytic anemia, megaloblastic anemia, hereditary spherocytosis, heterotaxy with asplenia and myelodysplastic syndrome (MDS).
- Also can be seen in premature infants.
