Surgical Treatment of Well-Differentiated Liposarcoma

Abstract

Between 1976 and 1998, we experienced ten cases of well-differentiated liposarcomas. In all cases surgical treatment was performed. In the first operation, we performed marginal resection in eight cases, wide resection in one case, and intralesional resection in one case. Local recurrence appeared in three cases. Two cases underwent marginal resection and one case underwent intralesional resection.
The prognosis of well-differentiated liposarcomas is comparatively good. Metastasis does not appear except when they are dedifferentiated. Moreover, sometimes it is clinically difficult to distinguish them from some benign fatty soft tissue tumors. It should be better to preserve the nerves and vessels which are attached to the tumor and to resect the other tissues which are attached to the tumor with a wide margin as much as possible in the first operation.
