Summary
Primary tumors of the lesser sac are rare, often misdiagnosed as retroperitoneal masses. This case highlights a myxoid liposarcoma, a unique and treatable variant.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Lesser sac tumors are uncommon and frequently misdiagnosed.
- Retroperitoneal lesions are a common differential diagnosis.
Purpose of the Study:
- To report a rare case of primary lesser sac myxoid liposarcoma.
- To review literature on primary lesser sac tumors, focusing on myxoid liposarcoma.
Main Methods:
- Case presentation of a 62-year-old male with abdominal distension.
- Diagnostic workup included physical examination, radiological imaging, image-guided biopsy, and surgical exploration.
- Histopathological examination confirmed myxoid liposarcoma.
Main Results:
- A large, multi-lobulated tumor originating from the lesser sac was identified.
- Initial biopsy suggested atypical lipoma, but final pathology confirmed myxoid liposarcoma.
Conclusions:
- Primary lesser sac liposarcomas are rare neoplasms.
- The myxoid variant exhibits unique biological behavior, sensitivity to chemotherapy/radiotherapy, and specific cytogenetic markers.
