Breast cancer is the second commonest primary tumour responsible for gastro
intestinal metastases after malignant melanoma. The real incidence of gastr
ointestinal metastases in breast cancer patients is probably underestimated
owing to the non-specific presenting symptoms and death of patients caused
by other more obvious metastases. The predominant histological subtype of
gastrointestinal metastases of breast cancer is invasive lobular carcinoma
and the median interval from diagnosis of primary breast cancer to gastroin
testinal metastases is five years. We report two cases of disseminated brea
st cancer with gastrointestinal involvement with a rather long survival.
