Summary
This case report details a retroperitoneal well-differentiated liposarcoma with lipoma-like and sclerosing components. The sclerosing type presented challenges in CT differentiation from other soft tissue tumors.
Area of Science:
- Oncology
- Radiology
- Surgical Pathology
Background:
- Retroperitoneal liposarcomas are rare soft tissue tumors.
- Well-differentiated liposarcoma (WDLS) can exhibit diverse histological patterns.
- Accurate preoperative diagnosis is crucial for effective management.
Observation:
- A case of retroperitoneal WDLS with both lipoma-like and sclerosing components is presented.
- The sclerosing subtype appeared as a solid density mass on computed tomography (CT).
- This imaging characteristic posed diagnostic challenges, mimicking undifferentiated liposarcoma and other soft tissue neoplasms.
Findings:
- Histopathological examination confirmed the presence of both lipoma-like and sclerosing WDLS.
- CT findings highlighted the difficulty in distinguishing the sclerosing component from aggressive tumors.
- Angiography revealed the ureteral artery as the primary vascular supply to the tumor.
Implications:
- This case underscores the importance of considering sclerosing WDLS in the differential diagnosis of retroperitoneal solid masses.
- Advanced imaging techniques and histopathology are essential for accurate classification.
- Understanding tumor vascularity, such as the prominent ureteral artery feeder, can inform surgical planning and interventional radiology approaches.
