Invasive breast cancer is the most common carcinoma in women, 23% of all cancers in the world. It is classified according to its histological pattern and expression of immunohistochemical markers; 75% are ductal type. The incidence of metastases is 10 to 80% of the cases according to their immunophenotype, the main sites of metastases are bone, visceral and brain.
A 64 years old lady with a history of radical left mastectomy due to unspecified breast cancer in 2000, received chemotherapy, radiation therapy and tamoxifen. After her discharge from hospital, the patient remained unattended. In 2014 she started with dysphagia, in 2016 was documented esophageal stricture by panendoscopy, three endoscopic dilations were performed, in the last one she presented incidental perforation. An esophagectomy was performed; the pathological study reported metastasis of ductal carcinoma of the breast.
Ductal carcinoma of the breast rarely metastasizes to the digestive tract but, its probability must have this and insist on monitoring of patients after their cancer treatment.
浸润性乳腺癌是女性中最常见的癌症，占全球所有癌症的23%。它根据组织学模式和免疫组化标志物的表达进行分类；75%为导管型。根据免疫表型，转移发生率为病例的10%至80%，主要转移部位是骨、内脏和脑。
一位64岁女性，2000年因未明确的乳腺癌行左侧乳房根治性切除术，接受了化疗、放疗和他莫昔芬治疗。出院后，患者未得到随访。2014年她开始出现吞咽困难，2016年经全面内镜检查证实有食管狭窄，进行了三次内镜扩张，最后一次扩张时出现了意外穿孔。行食管切除术；病理研究报告为乳腺导管癌转移。
乳腺导管癌很少转移至消化道，但有这种可能性，并且必须坚持对癌症治疗后的患者进行监测。
