Although breast cancer most frequently metastasizes to the bone, lung, pleura, liver, adrenal glands and brain, it can also affect other organs such as the small bowel and ovaries, especially if the type of cancer is infiltrating and lobular. We present a case of metastases to the small bowel and ovaries from pleomorphic type infiltrating lobular breast carcinoma presenting as intestinal obstruction. Barium transit study revealed a stenosis in the jejunum and another in the terminal ileum at the ileocecal valve area. A flat formation in the area of the ileocecal valve was observed on endoscopy but the results of biopsy were negative, a fairly frequent finding due to the absence of infiltration of the intestinal mucosa. Pathological and immunohistochemical study of the intestinal and ovarian surgical specimens confirmed the diagnosis of metastases from lobular carcinoma of the breast, which was corroborated by breast biopsy.
尽管乳腺癌最常转移至骨、肺、胸膜、肝、肾上腺和脑，但它也可累及其他器官，如小肠和卵巢，尤其是浸润性小叶癌类型。我们报告一例多形性浸润性小叶乳腺癌转移至小肠和卵巢并表现为肠梗阻的病例。钡剂通过研究显示空肠有一处狭窄，回盲瓣区域的回肠末端也有一处狭窄。内镜检查在回盲瓣区域观察到扁平肿物，但活检结果为阴性，由于肠黏膜未受浸润，这是相当常见的发现。对肠道和卵巢手术标本进行的病理及免疫组化研究证实为乳腺小叶癌转移，乳腺活检也证实了这一诊断。
