Huge liposarcoma of the left retroperitoneum

Liposarcoma is one of the most common soft-tissue sarcomas. Unless it grows to massive proportions, it rarely causes symptoms. A 64-year-old man presented with weight loss, asthenia, and increasing abdominal girth caused by a large liposarcoma in the left retroperitoneum. Despite resection with sarcoma-free margins and intensive follow-up evaluation, he died of a tumor recurrence 2 years later. Complete surgical resection of the liposarcoma is the only curative option, but establishing a prognosis remains a challenge.
