Moreover, there has been little in the literature to compare the MRI features … Liposarcoma is usually large (average diameter, >20 cm) and is a slow-growing tumor . There is a low incidence of distance metastasis (7%) compared to other histological subtypes that range from 15 to 34% [ … liposarcoma: [ lip″o-sahr-ko´mah ] a malignant tumor characterized by large anaplastic lipoblasts , sometimes with foci of normal fat cells. We aimed to test the hypothesis that in retroperitoneal dedifferentiated liposarcoma (DDLS) the presence of the dedifferentiated (DD) component at the resection margin is associated with adverse outcome. I was diagnosed July 2008 with dedifferentiated liposarcoma of the retroperitoneum. fatty stroma background. The retroperitoneum is deep in the abdomen (tummy) and pelvis, behind the abdominal lining, where organs such as the major blood vessels, kidneys, pancreas and bladder are located. METHODS: Patients who underwent resection with curative intent for retroperitoneal liposarcoma and who received NRT or surgery alone were identified in the US National Cancer Data Base (2004-2013). But when the interventional radiologist and the neurosurgeon came into the room, I knew that something was wrong from the look on their faces. Primary retroperitoneal liposarcoma (PRPLS) has a higher incidence within the age group of 60 to 70 years old, with no gender predominance.

Retroperitoneal sarcoma is a relatively rare type of cancer, accounting for just 15 percent of all soft tissue sarcomas and less than 1 percent of diagnosed cancers. This type of cancer grows … However, preoperative diagnosis is a common problem due to lack of characteristic clinical presentations. Soft tissue sarcomas are an extremely rare malignancy accounting only 1% of all tumors in adult patients [].Liposarcomas are the most common type of sarcomas arising in the retroperitoneum that could become life-threatening [2, 3].These tumors can grow to a massive size and involve adjacent structures that could make their control even more difficult []. Most are large at presentation, occurring in the 6 th to 7 th decades of life, with no gender predilection. Computed tomography scan-driven selection of treatment for retroperitoneal liposarcoma histologic subtypes. The standard of care treatment is surgical resection, though the role of neoadjuvant radiation is being examined. There are five subtypes of liposarcoma: well differentiated, dedifferentiated, myxoid, round cell and pleomorphic. Because of their rarity and anatomic location, these malignant tumors can cause a diagnostic dilemma and present several therapeutic challenges. 80% of primary retroperitoneal tumours are malignant, the commonest tumours being lymphoma and sarcoma.

As a consequence, the majority of patients with high-grade RLS will develop locally recurrent disease following surgery, and this constitutes the cause of death in most patients. It has been assumed that MRI, based on its high soft-tissue resolution, could discover and discern different subtypes of this tumor. Part of the challenge in making the diagnosis is there isn’t a specific list of symptoms for sarcoma. Within their subtypes – well differentiated (WDL), dedifferentiated (DDL), myxoid (MLS) and pleomorphic (PLS) - they exhibit a diverse genomic landscape. Search for more papers by this author In general, liposarcoma is a disease while lipoma is just a disorder.
