Summary
A rare pleomorphic liposarcoma in the anterior mediastinum presented with fatigue and hoarseness. Despite surgical resection and radiotherapy, metastasis occurred, highlighting this aggressive sarcoma
Area of Science:
- Oncology
- Thoracic Surgery
- Pathology
Background:
- Anterior mediastinal tumors can present with non-specific symptoms like fatigue and hoarseness.
- Liposarcomas are malignant tumors arising from adipose tissue, with pleomorphic liposarcoma being a rare and aggressive subtype.
Observation:
- A 70-year-old male presented with a 5-month history of fatigue and hoarseness.
- Chest computed tomography revealed a large anterior mediastinal mass.
- Needle biopsy confirmed high-grade malignant sarcoma, histopathologically diagnosed as pleomorphic liposarcoma.
Findings:
- The patient underwent complete tumor resection via median sternotomy.
- Post-operative follow-up revealed right supraclavicular lymph node metastasis at 6 months.
- Despite radiotherapy, liver metastasis appeared 16 months after the initial operation.
Implications:
- Pleomorphic liposarcoma is associated with a poor prognosis and requires vigilant monitoring.
- This case underscores the importance of early detection and aggressive management of rare mediastinal sarcomas.
- Further research into novel therapeutic strategies for advanced pleomorphic liposarcoma is warranted.
