Abstract
We describe a case of primary upper thoracic esophageal adenocarcinoma with gastric adenocarcinoma. A 59year-old man admitted for nasal bleeding was found in gastroesophageal endoscopy to have two pedunculated polyps in a slightly depressed lesion (0-Ip+0-IIc) in the upper thoracic esophagus and a broad tumor in a slightly depressed lesion (0-IIa+IIc) in the middle gastric body on the major curvature. Biopsies showed moderately differentiated adenocarcinoma of the esophagus and poorly differentiated adenocarcinoma of the stomach. Computed tomography showed an enlarged lymph node (106 rec L) diagnosed as metastasis. Tumors were resected by a transthoracic esophagectomy and total gastrectomy with D2 lymph nodes dissection. There were no barrett.s mucosa nor ectopic gastric mucosa in the resected specimen. The peripheral epithelium in the esophageal tumor was consistent with carcinoma in situ differentiating into adenocarcinoma. Such a case of primary esophageal adenocarcinoma is rare.
