Summary
This case report details a retroperitoneal liposarcoma successfully treated with surgical resection. The patient experienced resolution of weight gain, edema, and reactive pleural effusion post-operation.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Retroperitoneal liposarcoma is a rare malignant tumor.
- Reactive pleural effusion can occur secondary to intra-abdominal pathology.
Observation:
- A 58-year-old male presented with weight gain and edema.
- Imaging revealed an 11 cm retroperitoneal liposarcoma encasing the right kidney and bilateral pleural effusion.
- Two liters of ascites were noted during surgery.
Findings:
- The tumor was completely resected along with the right kidney via a transperitoneal approach.
- Histological diagnosis confirmed well-differentiated liposarcoma.
- Postoperative recovery was uneventful, with effusion resolution and normalized protein levels.
Implications:
- Complete surgical resection is effective for localized retroperitoneal liposarcoma.
- Resolution of reactive pleural effusion can be achieved after successful tumor removal.
- This case highlights the importance of considering malignancy in patients with unexplained effusions and abdominal masses.
