Polypoid lesions of the esophagus occur infrequently and may be benign or malignant. Pseudosarcoma, a malignant polypoid tumor of the esophagus is rare and appears to be a distinct pathological entity; the polypoid portion is composed of sarcomatous spindle cells and the base of the polyp shows in situ or invasive squamous cell carcinoma. We experienced a case of pseudosarcoma of the esophagus and report the case with the review of literature.
