The commonest sites for breast cancer metastases are the bones, lungs, liver, pleura, adrenals and central nervous system. However, although other sites have been reported, solitary metastases to the gastrointestinal tract are extremely uncommon. Widely disseminated gastrointestinal metastases may be found in up to 20% of patients. Although only 15% of patients with breast cancer will have the lobular variety, these make up the majority of patients with solitary gastrointestinal metastases. Here we present three cases where solitary lobular breast cancer metastases have been demonstrated to be the cause of bowel obstruction. In two cases of duodenal obstruction was demonstrated and in the third colonic obstruction. In all cases a focal extrinsic compression was found.
乳腺癌转移最常见的部位是骨骼、肺、肝脏、胸膜、肾上腺和中枢神经系统。然而，尽管有其他部位转移的报道，但胃肠道孤立转移极为罕见。高达20%的患者可能会出现广泛播散的胃肠道转移。虽然只有15%的乳腺癌患者为小叶型，但这些患者构成了胃肠道孤立转移患者的大多数。本文报告3例经证实为小叶型乳腺癌孤立转移导致肠梗阻的病例。其中2例表现为十二指肠梗阻，第3例为结肠梗阻。所有病例均发现有局灶性外压。
