A 68-year-old man who was admitted with dysphagia had undergone endoscopic and pathological examinations at another hospital, before being referred to our hospital with a diagnosis of esophageal adenocarcinoma. Endoscopy showed a type-3 lesion, 30-37cm from the incisors. The pathological examination showed the lesion to be squamous cell carcinoma. He underwent thoracoscopic esophagectomy, without neoadjuvant therapy. A pathological examination of the excised specimens showed the lesion to contain a squamous cell carcinoma component, an adenocarcinoma component and a basaloid-squamous carcinoma component. These components were similar in volume. The deepest part of the carcinoma was located at the adventitia. The squamous cell carcinoma had metastasized to the 106 recR lymph nodes. The pathological stage was pT3pN1cM0 and pStage III. Esophageal carcinomas with these 3 components are rare.
