Sonographic Appearances of Liposarcoma: Correlations with Pathologic Subtypes

Liposarcoma is the second most common malignant soft-tissue tumor. This entity is pathologically categorized into 4 subtypes: well-differentiated, myxoid, dedifferentiated and pleomorphic. Although features on magnetic resonance imaging and computed tomography for these 4 subtypes have been reported quite precisely, those on sonography have not been fully investigated. The present study was therefore aimed at clarifying the sonographic appearances of each liposarcoma subtype and assessing correlations with histopathology.

ConclusionWhile sciatic hernias are rare, lipomatous/ liposarcomatous tumors presenting as sciatic hernias are extremely rare. This case report highlights a combination of rare phenomena. The information presented adds to the current evidence that will guide accurate diagnosis and appropriate treatment of future cases.

SummaryRadiation therapy (RT) is an integral part of the treatment of adult soft tissue sarcomas (STS). In extremity STS, RT generally increases local control (LC) compared to wide excision alone while the magnitude of benefit depends on the individual risk profile. Neoadjuvant treatment results in less late toxicity paralleled by improved functional outcome but comes along with increased wound complications compared to postoperative radiation. In retroperitoneal sarcoma, neoadjuvant radiation seems to improve LC at least in liposarcomas while its impact in other histologies remains unclear. Postoperative radiation should ...

AbstractRetroperitoneal sarcomas (RPS) are rare heterogeneous tumors arising in the retroperitoneum with unique biological and behavioral patterns that are thought to be closely linked to histology. The aim of the study was to audit our results and analyze various clinico-pathological factors including surgical excision, histology, and their implications on the recurrences and survival outcomes in RPS. Retrospective analysis of patients treated at a tertiary referral center in India from March 2008 to July 2017 was performed. The clinico-pathological variables were analyzed for their association with tumor recurrence and s...

We report a case of a 66-year-old woman with a history of retroperitoneal liposarcoma resection who presented to the emergency department with abdominal pain. Ultrasonography revealed a large abdominal mass with renal displacement. Dynamic renal scintigraphy with 99mTc-DTPA was conducted to evaluate renal function. However, severe impairment of the right kidney function and abnormal tracer accumulation were observed during the examination. SPECT/CT was performed; 2 kidneys were successfully localized, and the recurrence of tumor was correctly detected.

ConclusionsWe present the first reported case of clear cell renal carcinoma synchronous with dedifferentiated liposarcoma of a limb. The association between renal cell carcinoma and dedifferentiated liposarcoma is unusual, and there are few reports of this presentation in the literature. More research about these tumors along with genetic tests needs to be performed to seek a better understanding of the fundamental basis of this rare association.
