Polypoid carcinoma of the esophagus: a distinct radiological and histopathological entity.

The radiological manifestations of four cases of polypoid carcinoma of the esophagus are reviewed. A large pedunculated intraluminal mass, mimicking a foreign body was seen in three of the four cases. Due to this predominant exophytic growth, the follow-up esophagogram was normal in two patients after radiotherapy, despite the very large size of the lesions. The unique histopathology and radiology of this entity are discussed.
