Stomach and Colon Metastasis from Breast Cancer / 이화의대지

ABSTRACT

Gastric metastasis from breast cancer is rare and only six cases have been reported in Korea. Colon metastasis is more rare than gastric metastasis. We report a 63-year-old woman with gastric and colon metastases of invasive lobular carcinoma of breast. She was diagnosed as right breast cancer, received right modified radical mastectomy 10 years ago and has been treated with chemotherapy and hormone therapy. Investigating for melena and a small caliber of stool, we found gastric and colon metastases. The diagnosis of metastatic breast cancer was made through gross pathologic and immunohistochemistry staining. We report a case with gastric and colon metastases from breast cancer and a review of the associated six case reports in Korea.
