Deceptive Giant Dedifferentiated Liposarcoma of the Esophagus: An Extremely Rare Surgical Case

Abstract

Dedifferentiated liposarcoma rarely occurs in the esophagus. It always has atypical clinical manifestations and different pathologic features, which usually lead to misdiagnosis and mistreatment. Given its poor prognosis, early and accurate diagnosis is of the utmost importance. The accumulation of similar cases is critical for surgeons and pathologists to raise awareness of such tumors. This report aims to discuss the diagnosis and provide a reference for the clinical diagnosis and treatment for pathologists and clinicians.

Esophageal Liposarcoma: A Case Report and Review of the Literature

“…and 11 additional case reports from the review of PubMed as described above, with duplicates excluded[2][3][4]6,[9][10][11][12][13][14][15]. Our case represents the 77th reported case of esophageal liposarcoma.…”

“…They are derived from primitive mesenchymal cells and usually arise from the esophageal submucosa [3]. Since the publication of the first case report in 1983, 76 cases of esophageal liposarcoma have been reported in the English-language medical literature [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The clinical presentation of these tumors is usually with symptoms of dysphagia, dyspnea, or, in some cases, regurgitation of the mass [2].…”
