We herein report a rare case of esophageal carcinoma with giant intramural metastasis to the stomach. Endoscopy revealed a 71-year-old man with deglutition disorder to have a lesion in the middle esophagus and a giant submucosal tumor about 60 mm in diameter in the gastric cardia with erosion on its top. Histopathologically, the tumor was shown to be moderately differentiated squamous cell carcinoma, so we diagnosed him with esophageal carcinoma with intramural metastasis to the stomach. Chemoradiation therapy was administered given to prevent regional recurrence, A complete response was achieved, and this patient remains alive without recidivation at 10 months.
In the past, there have been a few cases in which gastric lesions were diagnosed as intragastric metastasis before surgery, and as a result regarding the diagnosis of gastric submucosal tumor, many cases were diagnosed as intragastric metastasis only by surgery. This is a rare case of esophageal carcinoma with giant intramural metastasis to the stomach that has been successfully treated with chemoradiation therapy; thus, we report this case along with a discussion.
