Abstract

Dedifferentiated liposarcoma (DDL) is a rare soft tissue tumor that represents a non-lipogenic progression of well-differentiated liposarcoma (WDL). Unlike WDL, DDL has the propensity for metastasis and is associated with an increased incidence of local recurrence. For DDL of the extremities that is resectable with acceptable functional outcomes, treatment includes primary surgical resection with negative margins. Although rare due to advances in reconstructive techniques, amputation for DDL of the extremities should be considered in which appropriate tumor resection cannot be performed without adequate preservation of limb function. We present the clinical progression of a patient with a large DDL of the right thigh who was initially lost to follow-up, but ultimately underwent delayed definitive therapy with the intent for limb salvage. This case illustrates the importance of assessing neurovascular, osseous, and soft tissue involvement to properly predict and preserve limb function while achieving adequate tumor resection.
