[Carcinosarcoma of the esophagus: diagnostic importance of partial endoscopic polypectomy]

The clinical and pathological manifestations of a case of carcinosarcoma of the esophagus are reported. Barium swallow and endoscopy revealed a polypoid mass in mid esophagus. The tumor was large, pedunculated, covered by smooth mucosa with some erosions. Histologically the tumor was composed of a mixture of invasion keratinizing cells and intermingled bundle of spindle shaped cells resembling fibrosarcoma. The tumor was removed with surgery and did not show submucosa infiltration. It was not detected any metastasis or local recurrence during the 12 months follow-up period. The diagnosis was made by an endoscopic partial polypectomy. We conclude that partial polypectomy may be of value in preoperative diagnosis of esophageal polypoid mass.
