Clinical and pathological characteristics of carcinosarcoma of the esophagus: report of four cases.
Carcinosarcoma of the esophagus is a rare malignant neoplasm composed of both carcinomatous and sarcomatous elements. Four out of 850 patients with carcinoma of the esophagus or the cardiac portion of the stomach undergoing operation at Capital Hospital, Beijing, had carcinosarcoma of the esophagus. They ranged from 50 to 58 years old, but only 45% of all 850 patients with carcinoma were in the age group from 51 through 60 years old. All 4 patients with carcinosarcoma of the esophagus were men. On barium swallow esophagogram, the 4 patients had a characteristic intraluminal polypoid lesion in the middle third of the esophagus. Such lesions of the esophagus also can occur in patients with benign fibrovascular polyps, leiomyoma, and the polypoid form of esophageal carcinoma and esophageal melanoma. The last two can be differentiated from carcinosarcoma only by pathological examination after excision. After radical excision and esophagogastrostomy, the 4 patients were followed up for 19, 4, 4, and 3 years. They were in good condition without recurrence.
