Metastasis of a sigmoid carcinoma to the breast

Breast metastases are usually a rare event. We present the case of a 42-year-old patient with a primary carcinoma of the sigmoid metastatic to the breast and metastasis in the liver as well. Although seldom, it is important that metastatic cancer to the breast be differentiated from primary breast carcinoma as both the treatment and the prognosis differ significantly.
