What is a well-differentiated liposarcoma?

Disease definition. Well-differentiated liposarcoma (WDLS), the most common type of liposarcoma (LS; see this term), is a slow growing, painless tumor usually located in the retroperitoneum or the limbs. It is composed of proliferating mature adipocytes.

Is well-differentiated liposarcoma malignant?

Answer: Well-differentiated (WD) liposarcoma is a low-grade adipocytic malignancy that does not metastasize.

Can CT scan detect liposarcoma?

Diagnosing liposarcoma typically involves a physical exam, a biopsy (a procedure to extract a tissue sample from the tumor to be examined and tested for cancer cells in a lab), blood tests, and imaging tests including ultrasound, X-ray, MRI, or a CT scan.

What is the difference between well-differentiated and dedifferentiated liposarcoma?

Dedifferentiated, round cell and pleomorphic liposarcoma are high-grade, aggressive tumors with metastatic potential while well-differentiated and myxoid liposarcoma are low-grade tumors that follow a more indolent clinical course [1,2].

How common is well-differentiated liposarcoma?

Well-differentiated liposarcoma is the most common entity of all head and neck sarcomas and accounts for 30–40% of liposarcomas. It is locally aggressive and may recur if excision was not complete with a very low tendency to metastasis [9].

What is a well-differentiated tumor?

Well-differentiated cancer cells look and behave more like the normal cells in the tissue they started to grow in. Tumours that have well-differentiated cancer cells tend to be less aggressive. This means they tend to grow and spread slowly. Well-differentiated cancers are low grade.

Can liposarcoma be benign?

They both form in fatty tissue, and they both cause lumps. But these are two very different conditions. The biggest distinction is that lipoma is noncancerous (benign) and liposarcoma is cancerous (malignant). Lipoma tumors form just under the skin, usually in the shoulders, neck, trunk, or arms.

What does CT soft tissue neck show?

A CT Neck (Soft Tissue) is an exam that takes very thin slice images of the neck, starting from just above the ears and ending just below the clavicles (collar bone). This allows more accurate diagnosis of conditions involving areas such as the nasal passages, mouth, throat, vasculature, thyroid and parotid glands.

How can you tell the difference between a lipoma and liposarcoma?

The biggest distinction is that lipoma is noncancerous (benign) and liposarcoma is cancerous (malignant). Lipoma tumors form just under the skin, usually in the shoulders, neck, trunk, or arms. The mass tends to feel soft or rubbery and moves when you push with your fingers.

How can you tell the difference between a lipoma and a liposarcoma?

While both lipoma and liposarcoma form in fatty tissue and can cause lumps, the biggest difference between these two conditions is that lipoma is benign (noncancerous) and liposarcoma is malignant (cancerous).

Can you have liposarcoma for years?

Life expectancy for liposarcoma is often expressed in 5-year survival rates, that is, how many people will be alive 5 years after diagnosis. Well-differentiated liposarcoma has a 100% 5-year survival rate, and most myxoid types have 88% 5-year survival rates.
