Summary
A large retroperitoneal myxofibrosarcoma was surgically removed. Despite aggressive treatment, the patient experienced rapid metastasis, highlighting challenges in managing high-grade sarcomas.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- A 63-year-old male presented with flank pain and malaise.
- Imaging revealed a large retroperitoneal tumor adjacent to the right kidney.
Observation:
- The tumor, weighing 2,900g, was surgically excised.
- Histopathology confirmed high-grade myxofibrosarcoma.
Findings:
- The patient developed isolated lung metastasis, followed by lymph node metastasis.
- Despite surgical interventions and one cycle of chemotherapy (doxorubicin and carboplatin), rapid progression of liver and para-aortic lymph node metastases occurred.
Implications:
- This case underscores the aggressive nature of high-grade myxofibrosarcoma.
- The rapid progression and poor response to treatment highlight the need for novel therapeutic strategies for advanced myxofibrosarcoma.
