Esophageal Cancer with a Synchronous Multiple Carcinoid of the Duodenal Bulb.

Carcinoid tumors of the duodenum are relatively rare. Although they were considered benign lesions, they are now classified malignant, occasionally with poor prognosis. We report a case of esophageal cancer with a synchronous multiple carcinoid of the duodenal bulb. An upper endoscopy visualized with esophageal scan disclosed a stenotic lesion in the lower esophagus and revealed multiple 4--5-mm-diameter masses which were on the fore wall of the duodenal bulb. The postoperative pathology report confirmed the diagnosis of esophageal squamous cancer and duodenal bulb carcinoid.
