A CASE OF SUPERFICIAL ESOPHAGEAL CARCINOMA WITH GIANT INTRAMURAL METASTASIS TO THE STOMACH

Abstract

We encountered a case of superficial esophageal carcinoma with giant intramural metastasis to the stomach. Esophageal and gastric lesions were identified on endoscopy in a 76-year-old man. The esophageal lesion was 7 mm in diameter and located in the lower thoracic esophagus. The gastric lesion was a giant submucosal tumor approximately 70 mm in diameter, located in the posterior wall of the upper gastric body. On endoscopic ultrasonography-guided fine needle aspiration and biopsy, the gastric lesion was diagnosed as squamous cell carcinoma. Endoscopic ultrasonography revealed the esophageal lesion as a superficial carcinoma invading the submucosa, diagnosed on biopsy as also representing squamous cell carcinoma. Stomach wall metastasis from a superficial esophageal carcinoma was therefore diagnosed.
