Metastasis of cancer to cancer: report of a case of esophageal carcinoma metastasizing to early gastric cancer.
A rare case of esophageal carcinoma metastasizing to early gastric cancer is reported herein. A 66 year old man who had experienced dysphagia for 8 months was preoperatively diagnosed as simultaneously having esophageal and gastric cancers. Thus, a lower esophagectomy and total gastrectomy with paraesophageal and paragastric lymph node dissection were performed. The surgical specimen revealed an ulcerative tumor in the lower esophagus and a slightly depressed lesion with a central elevation similar to that of early type IIc + IIa gastric cancer in the upper part of the stomach. Microscopically, the esophageal tumor was revealed to be well differentiated squamous cell carcinoma while the gastric tumor was found to be early gastric cancer with a metastatic focus of esophageal cancer in the center. Though less than one hundred cases of metastasis of cancer to cancer have previously been reported, metastasis from cancer of one digestive organ to that of another digestive organ is very rare. To our knowledge, this report represents the first case of an esophageal carcinoma metastasizing to a gastric carcinoma.
