Renal, gastric, and multiple intestinal metastases of invasive ductal carcinoma of breast / 대한내과학회지

ABSTRACT

We describe a 53-year-old woman with renal, gastric, and multiple intestinal metastases of invasive ductal carcinoma of breast. She was diagnosed as left breast cancer of stage II, received left modified radical mastectomy 10 years ago and has been followed up without any evidence of residual disease. During investigation for indigestion and lower abdominal pain, we found multiple masses in left kidney, multiple levels of colon, ovary, peritoneum and bone. The histology of the tissue taken from renal mass was adenocarcinoma, which had identical features with those of masses resected from her left breast 10 years ago. During 28 month palliative chemotherapy, we found gastric metastasis of breast cancer and finally, the colonic metastatic masses caused intestinal obstruction. The diagnosis of gastrointestinal metastases of breast cancer is very important in the view of improvement of survival and quality of life because they can lead to intestinal obstruction, bleeding, and perforation.
