Isolated metastatic extremity liposarcoma to the liver, an uncommon and transient finding.

Garces CA, Reith JD, Grobmyer SR, Hochwald SN - World J Surg Oncol (2008)

Bottom Line: An extensive evaluation revealed isolated disease to the liver.The lesion was surgically removed with a right hepatic lobectomy and the pathology was consistent with metastatic myxoid/round cell liposarcoma.As expected, the patient experienced progression of disease at sites outside of the liver 5 months after the liver resection.

ABSTRACT

Background: Extremity liposarcomas can metastasize to different areas of the body but have rarely been demonstrated to metastasize to the liver. Due to the unusual occurrence of isolated metastatic extremity liposarcoma to the liver, the optimal treatment of this condition is unknown.

Case presentation: Less than one year after resection of a myxoid/round cell liposarcoma of the left lateral calf, a 61-year-old male presented with a CT scan showing a 2 cm low-density lesion in the right lobe of the liver. The lesion tripled in size over the next few months. An extensive evaluation revealed isolated disease to the liver. The lesion was surgically removed with a right hepatic lobectomy and the pathology was consistent with metastatic myxoid/round cell liposarcoma.

Conclusion: Although extremity liposarcoma rarely metastasizes solely to the liver, the best chance at cure is with complete resection. Unfortunately, cure rates are very low in the setting of metastatic disease. As expected, the patient experienced progression of disease at sites outside of the liver 5 months after the liver resection.

Figure 2: Histologic section of the primary tumor in the extremity showing a liposarcoma.

Mentions: A 61-year-old male noted a mass in his left lateral calf. A biopsy was performed revealing a myxoid liposarcoma. The patient subsequently underwent resection of an 8.0 × 6.0 × 3.5 cm tumor with wide margins (Figure 1). Histologically, greater than 95% of the mass consisted of myxoid liposarcoma with extensive hypercellular ("transitional") foci (Figure 2), and less than 5% consisted of round cell liposarcoma (Figure 3). The tumor was classified as grade 2 of 3.
