Giant liposarcoma of the esophagus with Li-Fraumeni-like syndrome

Abstract

Primary esophageal liposarcoma is a rare malignancy, with only 25 cases reported in the English literature. In this report, we present a new case of giant esophageal liposarcoma in a 49-year-old woman with a family history of upper gastrointestinal tract cancer. This was a transmural tumor located in the lower esophagus. Subtotal esophagectomy was successfully performed, and histopathology revealed a well-differentiated liposarcoma. The patient was followed-up for 20 months without recurrence. However, asynchronous ovarian serous adenocarcinoma was found 1 year after the esophageal surgery, and Li-Fraumeni-like syndrome was diagnosed.
