Abstract: We report a carcinoid tumor in the mucosal layer of the esophagus of a 63-year-old man. Barium X-ray and endoscopy indicated the tumor to be a polypoid lesion in the lower esophagus. Endoscopic ultrasonography (EUS) demonstrated the lesion to be a sharply demarcated hyperechoic tumor in the mucosal layer. Biopsy yielded a diagnosis carcinoid of the esophagus. In the resected specimen of the esophagus, the tumor was 11 mm in longest dimension with a shallow depression on it smooth surface. Histologically, the tumor was located in the mucosal layer, as shown by EUS, and was composed of small round cells which were positive for argyrophil, but not argentaffine. Carcinoid tumor of the esophagus found at an early stage, and localized in the lamina propria layer, is very rare. The present case is the second report in Japan.
