[Small bowel metastasis from breast cancer: a case report].
Breast cancer is a common malignancy in women and frequently metastasizes to various organs such as liver, lung, brain, bone and so on. But metastasis to gastrointestinal tract is rare. We describe a 73-year-old woman with small intestinal metastasis of breast cancer. She was diagnosed as right breast cancer in stage I, received modified radical mastectomy 6 years ago and had been followed up without any evidence of residual disease. During investigation for lower abdominal pain and weight loss of 9 kg, we found a small bowel mass. The histology of the tissue taken from small bowel mass was adenocarcinoma, poorly differentiated. The immunohistochemical stain of this specimen showed 75% positivity of estrogen receptor and 90% positivity of progesterone receptor. This is a case of small bowel metastasis from breast cancer and we report this case with a review of literatures.
