Giant liposarcoma of the esophagus: A case report

Liposarcomas rarely develop in the aerodigestive tract.Here,we present a primary esophageal liposarcoma that was discovered between the T3 and T7 levels of the esophagus during right pleural exploration of a 51-year-old male patient.The patient had presented with non-specific symptoms,including progressive dysphagia over the previous 6 mo,without complaints of chest or epigastric pain,regurgitation,or weight loss.A radical three-hole esophagectomy was performed.The tumor was extremely large(14 cm × 7.0 cm × 6.5 cm),but completely encapsulated.Upon histological examination,the tumor was diagnosed as a giant,well-differentiated esophageal liposarcoma with a dedifferentiated component.Non-specific radiological and endoscopic results during the clinical work-up delayed diagnosis until post-operative histology was performed.In this report,the clinical,radiological and endoscopic diagnostic challenges specific to the case are discussed,as well as the surgical and pathological findings.
