Adenocarcinoma Metastasis to the Breast

Metastasis to the breast from extramammary tumors is extremely rare accounting for less than 0.5%. Very limited case reports are published with the established diagnosis. Lung carcinomas, gastric carcinomas and melanomas are relatively more frequent primary sites causing the matastasis. Diagnosing metastatic breast cancer can be challenging, a thorough physical examination and a high index of suspicion is required. When deciding upon a management plan, the extent of dissemination and the life expectancy should be taken in consideration. Most of colorectal metastasis to breast carry a poor prognosis, hence palliative care is usually the management of choice. Here we report a case of a 51-year-old female who is a known case of rectosigmoid adenocarcinoma which has metastasized to the breast during the course of her treatment in our institute. Upon diagnosing the patient with breast metastasis palliative treatment was the managment of choice. As expected, this patient had a poor prognosis and has died after one year of being diagnosed with the metastatic disease.
