 The patient was a 55-year-old man who was found to have an esophageal tumor because of increasing dysphagia about four months ago. Barium swallow esophagogram and endoscopy demonstrated a large polypoid lesion in the lower thoracic esophagus. The size of this tumor was about 9 cm. Histological examination of the EMR specimen revealed that it was a carcinosarcoma. Thoracic esophagectomy with cervical, thoracic, abdominal lymph node dissection was performed. Histopathological findings showed squamous cell carcinoma and sarcoma-like proliferation of spindle-shaped atypical cells. A transitional feature was observed between the two sides. Therefore it was diagnosed as a so-called carcinosarcoma. Three months after the operation, both liver lobes had multiple metastatic lesions. Furthermore, four months later, the lung field had small metastatic lesions. The patient died nine months after his operation. Carcinosarcoma of the esophagus is a comparatively rare malignant tumor. We reported a case of esophageal so-called carcinosarcoma and reviewed some literature on the subject.
