Typical disease course of dedifferentiated liposarcoma in an elderly patient, who presented with a recurrent RLS in February 2011 2 years after primary surgery (A). The patient was treated with neoadjuvant radiotherapy (45 Gy in fractions of 1.8 Gy) and macroscopically completes resection. In May 2012, a solitary metastasis in the right liver lobe (B) was treated with RF ablation. In September 2012, a solitary 1.6 cm metastasis was removed thoracoscopically from the right lower lobe. In May 2013, a second retroperitoneal recurrence developed (B) for which repeat macroscopically complete surgery was performed. In September 2014, a small recurrence was noted against the left iliac bone [(C) arrow] for which additional surgery is planned. No other local or metastatic locations were noted.
