Abstract
We herein report a case of synchronous triple cancer involving the esophagus, stomach (double cancer), and ureter.
A 62-year-old man was diagnosed as having double cancer of hte esophagus and stomach by endoscopy performed for a follow-up study of gastric ulcer. Preoperative screening abdominal ultrasonography showed a right hydronephrosis, and a cytological examination of the urine revealed malignant transitional cells. A preoperative diagnosis of synchronus triple cancer (esophagus, stomach and ureter) was thus made. After an endoscopic mucosal resection for the early esophageal cancer, a radical total gastrectomy and a right nephroureterectomy were successfully carried out. Postoperative pathological examination revealed that the esophageal cancer was squamous cell carcinoma, the gastric cancer was well-differentiated adenocarcinoma, and the ureteral cancer was transitional cell carcinoma. Whenever we encounter cancers of the gastrointestinal tract including hepato-biliary-pancreatic system the possible coexistance of multiple malignancies occurring in other organs must be kept in mind.
