title: Giant lesser sac liposarcoma mimicking infected pancreatic pseudocyst.
abstract: The most common site for abdominal liposarcoma is the retroperitoneum. We report a 32-year-old man with lesser-sac myxoid liposarcoma with extensive cystic degeneration. Cystogastrostomy was attempted elsewhere with a misdiagnosis of pancreatic pseudocyst. However, the procedure was abandoned after biopsy, which showed features of liposarcoma. The patient was re-explored at our institute 2 weeks later. Complete excision of the tumor was done. Histology revealed features of myxoid liposarcoma. The patient received adjuvant radiotherapy and is doing well 12 months later.
