Retroperitoneal liposarcoma (RLS) is a rare, biologically heterogeneous tumor that present considerable challenges due to its size and deep location. As a consequence, the majority of patients with high-grade RLS will develop locally recurrent ...

2025年2月14日 · Retroperitoneal liposarcoma is a subtype of liposarcoma and is a malignant tumor of mesenchymal origin that may arise in any fat-containing region of the body. It is one of the most common primary retroperitoneal neoplasms. Most cases occur in patients in the 5 th to 7 th decades of life, with no gender predilection 4.

Retroperitoneal sarcomas comprise approximately 10% of all soft tissue sarcomas. Though any soft tissue sarcoma histologic types may arise in the retroperitoneal space, liposarcoma (especially well-differentiated and dedifferentiated types) and leiomyosarcoma do …

Retroperitoneal liposarcoma frequently recurs within 2 years of the initial surgical resection. For the early detection of recurrent retroperitoneal liposarcomas, a shorter follow‐up interval with CT or MRI would be helpful. Keywords: liposarcoma, recurrence, retroperitoneal.

2023年3月20日 · Liposarcoma, a tumor of lipoblasts, is a rare mesenchymal neoplasm that involves deep soft tissues, including the esophagus, retroperitoneum, and popliteal fossa.[1] The relative frequency of liposarcoma at various body sites is dependent on the tumor subtypes.

2024年4月28日 · Intraperitoneal origin, however, is an extremely rare location with unknown incidence, as it has only been mentioned in case reports. This paper presents a case of DDLPS arising from the porta hepatis that was initially misdiagnosed and complicated by multiple recurrences. It also reviews the literature on intraperitoneal liposarcoma.

2014年3月13日 · Peritoneal liposarcoma is a rare mesenchymal tumour and identification of fat on CT images can point to the diagnosis. Presence of areas of soft tissue attenuation within the fatty tumour is the hallmark of de-differentiation.

This article provides an in-depth review into the natural history, pathology, clinical manifestations, and prognostic features of retroperitoneal liposarcomas. It also discusses the reliability of diagnostic procedures and novel curative approaches …

2021年4月1日 · Liposarcoma is a soft tissue malignancy, commonly observed in the extremities. However, retroperitoneal liposarcoma is seldom reported and its diagnosis is frequently neglected. This study aims to present the clinical characteristics, diagnosis, and prognosis of five liposarcoma subtypes and report our experience of patient treatment. Methods ...

2015年2月9日 · Retroperitoneal liposarcoma (RLS) is a rare, biologically heterogeneous tumor that present considerable challenges due to its size and deep location. 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.
