title: [Polypoid pseudosarcomatous carcinoma of the esophagus. Report of two cases with favorable outcome after medical treatment].
abstract: The authors report two cases of esophageal polypoid pseudosarcoma with favorable outcome after endoscopic and medical treatment. Neither of the two patients could undergo general anesthesia. Endoscopic resection or monopolar electrocoagulation of the tumor was associated with chemotherapy and radiation therapy. A complete response of the tumor was observed in both cases. The two patients were alive and well with no evidence of recurrence or metastasis 3 and 5 years after diagnosis. Immunohistochemical study of those two tumors with monoclonal antibodies to intermediate filaments (keratin and vimentin) suggests duality in the spindle cell component. It may explain the biological behaviour of these particular cancers that have a better prognosis than other types of squamous cell carcinomas of the esophagus.
