Proximal Gastrectomy in a Case of Giant Gastric Liposarcoma and a 5-Year Follow-Up

Even though liposarcomas account for 10–20% of all mesenchymal malignancies, they are extremely rarely located in the stomach. We report the case of a female patient with gastric liposarcoma. CT revealed a giant hypoechogenic tumour subcardially on the posterior gastric wall. Endoscopic tumour resection by piecemeal technique was done, and a lipoma was confirmed on histopathological examination. A recurrent bleeding tumour was proven 6 weeks later. The patient underwent an open proximal gastrectomy with pyloroplasty, and liposarcoma was surprisingly revealed in the resected specimen, finally. Five years later, our patient had been without recurrence or any somatic difficulties. The CT finding of a submucosal fatty tumour with heterogeneous density within the gastric wall should raise the suspicion for liposarcoma. The goal is the surgical removal of the tumour with sufficient margins ensuring R0 resection.
