Liposarcoma is most commonly found in the extremities, as well as the retroperitoneum and also in the esophagus.
Liposarcoma also known as myxoid liposarcoma of the extremities presents as a deep mass in the lower extremity.
The most common liposarcoma is well-differentiated liposarcoma which grows slowly and generally does not spread to other parts of the body.
Well-differentiated liposarcoma also has a tendency to regrow after initial treatment.
A more aggressive form of well-differentiated liposarcoma is called dedifferentiated liposarcoma.
A liposarcoma lump may feel like a soft or rubbery lump under your skin.
You may be able to move the liposarcoma lump by pushing on it with your fingers.
Sclerosing well-differentiated liposarcoma is more commonly seen in the retroperitoneum and paratesticular area.
It is characterized by the presence of scattered bizarre stromal cells with hyperchromatic nuclei associated with multivacuolated lipoblasts.
The cells are present in a dense collagenous stroma.
Soft tissue sarcomas occur in approximately 5000 patients in the United States per year.
Overall, liposarcomas account for less than 20% of all soft tissue sarcomas, and the average patient age at presentation is 50 years.
Liposarcoma is a rare type of cancer that develops in your fatty tissue.
This type of tumor can grow anywhere in your body.
Common places include your abdomen, thigh, and behind your knee.
A liposarcoma is a malignant tumor.
Liposarcoma can be life-threatening, but it depends on the type.
Well-differentiated liposarcoma has a 100% 5-year survival rate, and most myxoid types have 88% 5-year survival rates.
Round-cell and dedifferentiated liposarcomas have a 5-year survival rate of about 50%.
If you have a type of liposarcoma, you have a very rare form of cancer.
Many times, healthcare providers can successfully treat this condition with surgery that removes and essentially cures the cancer.
But some liposarcomas come back. You may need to have regular checkups for many years after completing treatment.
Pleomorphic Liposarcoma is the least common form of liposarcoma that affects an arm or leg, a pleomorphic sarcoma is often more aggressive than other liposarcomas, spreading to other sites of the body such as lung and into soft tissue.
