 An 80-year-old male was admitted to our hospital because of dysphagia for the past month. Esophagography showed a large spindle shaped elevated lesion located in the middle to lower esophagus. Endoscopic examination of the esophagus revealed a large spindle shaped tumor from 28 to 38cm from the incisors. Endoscopic findings using iodine staining revealed that the tumor was unstained and the surrounding mucosa of the tumor was stained. We suspected this tumor was carcinosarcoma of the esophagus because of its unique shape, so we performed esophagectomy. Histopahtologic examination of the tumor revealed well differentiated squamous cell carcinoma with prominent keratinization. Carcinosarcoma, squamous cell carcinoma and malignant melanoma were mentioned as possible differential diagnoses of the tumor, which presented such a unique form.
