Pseudosarcoma of the esophagus. Three new cases and review of the literature.
Three newly found patients with an esophageal pseudosarcoma are described. The features of this unusual polypoid tumor are reviewed based on these three patients and 21 additional reported patients. The origin of the sarcomatous element as a metaplastic reaction to the underlying carcinoma is discussed. The exuberant growth may present with obstructive symptoms earlier than the usual carcinoma of the esophagus, permitting curative surgical resection in some patients.
