A case of esophageal carcinosarcoma is described herein. A 58-year-old man presented with dysphagia and was admitted to our hospital. Imaging studies revealed a type 3 tumor in the upper intrathoracic esophagus with direct invasion to the left main bronchus. Analysis of a biopsy specimen revealed carcinosarcoma. The patient underwent esophageal bypass and chemoradiotherapy. Eight months after surgery, he died of esophago-bronchial fistula. Autopsy examination revealed liver metastasis, peritoneal dissemination and intramural metastasis. The sarcomatous component was predominant in the intramural and liver metastatic lesions.
