A case of resected mediastinal liposarcoma

Abstract

A 56-year-old woman consulted us regarding a tumor shadow in the anterior mediastinum in May 2009. Chest CT showed a mass in the anterior mediastinum consisting of fat with slight enhancement. Chest MRI showed a mass consisting of fat and solid components. She was diagnosed with a mature teratoma, and underwent surgery. The tumor was resected by median sternotomy and diagnosed as a mucinous neoplasm based on a perioperative pathological study. The specimen was a yellow mass. On postoperative pathological analysis, a mixed liposarcoma was identified.
