Abdominal pain with anorexia in patients with breast carcinoma.

Breast cancer is the second commonest primary tumour responsible for gastrointestinal metastases after malignant melanoma. The real incidence of gastrointestinal 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 gastrointestinal metastases is five years. We report two cases of disseminated breast cancer with gastrointestinal involvement with a rather long survival.
