General
- Benign and rare.
- Typically asymptomatic and hormonally inactive.[1]
- Symptoms: back or abdominal pain.
- Diagnosis - usu. by abdominal CT.
Treatment:
- Watchful waiting if small (<=7 cm) and asymptomatic.[1]
Microscopic
Features:[2]
- Adipose tissue.
- Hematopoietic elements from all three lineages:
- Erythroid.
- Myeloid.
- Megakaryocytic.
- +/-Calcification.[1]
DDx:[3]
- Angiomyolipoma of the kidney.
- Lipoma.
- Liposarcoma.
- Teratoma.
