Abstract

Well-differentiated liposarcomas of the extremities are one of the most frequent types of malignant soft tissue tumors in adults. These tumors are typically locally aggressive and show a tendency to recurrence after surgical excision even though they do not metastasize and very rarely dedifferentiate. Its clinical presentation is generally a progressively growing mass causing aesthetic, functional, or compressive symptoms depending on the tumor’s size and localization. Several authors recommend a wide excision with free margins in order to minimize the risk of recurrence, while others report good results and a low rate of recurrence with more conservative or even marginal excision thereby avoiding complications due to surgical site morbidity. We present a retrospective study of 11 patients with a large-sized well-differentiated liposarcoma of the lower limb with a mean follow-up of 3.2 years. The mean size was 22 × 19 × 17 cm, and a marginal resection was made, respecting the affected neurovascular structures, in all cases. Only one recurrence was found and the functional results were 81.6% according to the MSTS functional scale 1 year after surgery. We believe that the marginal excision is a good alternative when the tumor is located near vascular or nerve structures, and as to our experience, it is not associated with elevated recurrences.
