Hazardous giant pharyngoesophageal liposarcoma.

A man in his early 80s presented to the otorhinolaryngology department with progressively worsening dysphagia to solids and a recent episode of difficulty breathing accompanied by a very brief expulsion of a solid mass from the mouth. Based on the endoscopic appearance of a fatty lesion of an elongated mass with a thick stalk on the posterior pharyngeal wall, a diagnosis of the benign fibrovascular polyp was given after clinical and radiological correlation. The pharyngeal polyp was resected at the base of its pedicle by transoral endoscopy with a thunder beat vessel sealing device. Histopathological examination of the mass revealed a well-differentiated liposarcoma composed of mature adipocytes. Following surgical excision, the patient made a full recovery. This case signifies the integrated role of preoperative biopsy, new surgical technologies and targeted therapies in managing pharyngoesophageal polyps.
