Liposarcoma is a malignant tumor that arises in fat cells in deep soft tissue, such as that inside the thigh or in the retroperitoneum.
They are typically large bulky tumors which tend to have multiple smaller satellites extending beyond the main confines of the tumor.
what is the retroperitonium?
The retroperitoneum (adj. retroperitoneal) is the anatomical space behind (retro) the abdominal cavity.
- Primarily retroperitoneal:
- urinary
- adrenal glands
- kidneys
- ureter
- bladder
- circulatory
- aorta
- inferior vena cava
- digestive
- esophagus (part)
- rectum
- Reproductive
- uterus
- Secondarily retroperitoneal:
- the head and neck of the pancreas (but not the tail)
- the second and third portions of the duodenum (but not the first or fourth)
- ascending and descending portions of the colon (but not the transverse or sigmoid)
Here's a case from http://www.msnbc.msn.com/id/25680599/wid/11915773?GT1=43001
REDMOND, Ore. - Throughout her life, Linda Rittenbach has struggled with her weight.
“You get bigger and bigger and bigger,” said Rittenbach, who has two grown children. “And then you go to your doctor and they tell you, ‘You need to lose weight — you’re fat!’”Rittenbach had tried every diet, every workout, but the pounds wouldn’t go away. Doctors suggested weight loss surgery.
Doctors told her a 140-pound cancerous tumor — a rare kind of liposcarcoma — was growing near her stomach. They said it had likely been growing for 15 to 20 years.
here's another case from sarcoma alliance: all they say of interest here is: Andy has well-diff. liposarcoma of the retroperitnium.
