Giant esophageal polyp: a clinical and radiological entity with variable histology.

Giant pedunculated esophageal polyps are very rare. They may stay asymptomatic for a long time, and first come to the attention of the patient and the clinician after regurgitation into the mouth. Regurgitation, however, can be dangerous and has been known to lead to asphyxia and death due to closure of the larynx by the polyp mass. For this reason resection of the giant polyp is essential when it is discovered. We have seen four cases of giant esophageal polyps (GEP) at our institution. All four patients have undergone removal of the giant polyps. The histological diagnoses were fibrovascular polyp, liposarcoma, hamartoma and multiple lipomas. The mode of clinical presentation, radiological appearances, variable histological diagnoses, and therapy options in these four patients are presented along with a review of the literature.
