Background:
Mediastinal lipoma/liposarcoma is a rare tumor of the mediastinum.
Case Presentation:
This article reported one case of giant anterior superior mediastinum well-differentiated liposarcoma involving the left thoracic cavity with symptom of dysphagia. The mediastinum liposarcoma was completely resected through a left thoracotomy. Histologic examination and molecular pathological test clarified the diagnosis as well-differentiated mediastinal liposarcoma. There has been no evidence of recurrence during the 8 months follow-up.
Conclusion:
Molecular pathological examination of the MDM2, CDK4 and p16 gene in tumors provides the diagnostic gold standard in distinguishing well-differentiated liposarcoma from lipoma. Complete surgical resection is the first-line treatment choice for mediastinal lipoma/ liposarcoma.
