 The patient was a 70-year-old man who came to our hospital with the chief complaint of heartburn occurring without relationship to meals. Gastroendoscopy showed a reddish area with an irregular surface in the mid-thoracic esophagus. The lesion was achromatic on iodine staining and was identified by biopsy to be a well differentiated squamous cell carcinoma. Endoscopic mucosal resection (EMR) was performed for treatment of the lesion, using the two-channel method. Histopathological examination confirmed that the lesion was a well differentiated squamous cell carcinoma partly infiltrating to the m3. After the patient gave informed consent, no additional treatment was performed. Subsequent examinations did not suggest the presence of remnant tumor. At 13 months after EMR, the patient abruptly developed right hypochondralgia, and cholangiocarcinoma was found. To improve the prognosis of esophageal cancer, when follow-up is performed, attention should not only be paid to metastasis in the head and neck region, but also to the development of neoplasms elsewhere.
