Summary
Giant retroperitoneal lipomas are rare benign fatty tumors. This case highlights successful surgical removal and long-term recovery for a large retroperitoneal lipoma.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Retroperitoneal lipomas are exceptionally rare neoplasms.
- Benign fatty tumors in the retroperitoneum present diagnostic challenges.
Observation:
- A 32-year-old female presented with a 2-year history of pain and an abdominal mass.
- Imaging revealed a large retroperitoneal mass posterior to the ascending colon.
- Surgical exploration identified a large, encapsulated tumor weighing 3.4 kg.
Findings:
- Histological examination confirmed the tumor as a benign lipoma, composed of fatty cells.
- The giant retroperitoneal lipoma measured 20 x 13 x 10 cm.
Implications:
- Complete surgical excision is an effective treatment for giant retroperitoneal lipomas.
- Long-term follow-up indicates a favorable prognosis with no recurrence after 17 years.
