A 77-year-old male with a long history of alcohol consumption and smoking was admitted for hoarseness and dysphagia. Computed tomography revealed thickening of the middle intrathoracic esophageal wall and multiple mediastinal lymph node swellings. Esophagogastroduodenoscopic examination disclosed an advanced-stage squamous cell carcinoma lesion in the middle intrathoracic esophagus with synchronous early stage Barrett's adenocarcinoma. The patient underwent endoscopic submucosal dissection for the adenocarcinoma followed by chemoradiation therapy for the squamous cell carcinoma. In spite of their common risk factors, the simultaneous manifestation of esophageal squamous cell carcinoma and Barrett's adenocarcinoma is extremely rare and requires further study.
