Abstract

Metastatic cancer to the esophagus is rare and the breasts are the most common primary tumors that metastasize to the esophagus. Since metastatic breast cancer is located in the submucosal layer, diagnosis by general forceps biopsy is difficult. Hence, various techniques including endoscopic ultrasound guided fine needle aspiration, endoscopic ultrasound guided fine needle biopsy, unroofing technique, and submucosal tunneling method are used for diagnosis. Moreover, the patient's medical history should be inspected carefully and previous histological findings of cancer should also be evaluated. Herein, the authors report a case of metastatic breast cancer along with literature reviews. Endoscopy was performed in patient who had undergone breast cancer surgery 13 years previously. Histological examination from a midesophageal stricture was normal. Endoscopic ultrasound was performed and uneven hypoechoic masses were found in the third layer of the esophageal wall. The esophageal stricture was finally diagnosed as metastatic breast cancer by endoscopic ultrasound-guided fine needle biopsy.
