Progressive dysphagia from an esophageal liposarcoma, a complex problem in a challenging setting

Esophageal lipomatous tumors are extremely rare, and due to their nonspecific clinical manifestations, distinguishing them is nearly impossible without the aid of histopathology, immunohistochemistry, and molecular analysis. Complete resection with clear margins is the treatment of choice to avert metastasis, improve prognosis, and prevent complex complications due to the polyp growth and location. We present the case of a 70-year-old male who presented in 2023 with dysphagia due to an esophageal polyp; surgery was recommended. However, he did not accept any treatment due to fear. One year later, and since his symptoms worsened, he finally decided to undergo endoscopic treatment at another medical institution. However, during that procedure, he suffered severe asphyxia, which caused a cardiopulmonary arrest. Once he partially recovered and because he continued with dysphagia, surgery was completed, and the polyp was removed. The final diagnosis was esophageal liposarcoma.
