Liposarcomas are a subtype of soft tissue sarcomas that often appear in the fth and sixth decades and can occur in a range of anatomical places. However, liposarcomas of omental origin are uncommon, with only a few examples reported worldwide. The following is a case report of a 32- year-old woman who presented with abdominal pain and early satiety, as well as an abdominal mass. She underwent investigations, which revealed a 20x15-cm intraabdominal mass, and was scheduled for surgical exploration, which revealed a 20x8x18-cm mass arising from the omentum with no capsulation or feeding vessel. The lump, together with the greater omentum, was excised and sent for histological investigation, which revealed it to be a liposarcoma of the omentum. In conclusion, our case report demonstrates that liposarcoma of the omentum has vague clinical symptomatology and that omentectomy may be recommended to prevent metastasis, but further research studies are needed before it can be adopted as the therapy of choice.
