Abstract

Background
Metastasis from extramammary primary tumor to breast is extremely rare.
Case Summary
A 59-year-old woman with 1-year history of rectal cancer presented with asymptomatic breast mass. At 16 months after the diagnosis of rectal mucinous adenocarcinoma, a breast mass was confirmed by ultrasonography and identified by pathology and immunohistochemistry as a metastasis from the rectal cancer. Treatments included chemotherapy (6 cycles: 300 mg irinotecan on day 1, 4.5 mg raltitrexed on day 2, 450 mg bevacizumab on day 3), radiotherapy, and surgical resection. Two years of follow-up examinations (6-months intervals) showed no evidence of recurrence or novel distant metastasis.
Conclusion
Breast metastasis from rectal carcinoma is a rare secondary malignancy. Final diagnosis can be established by histopathology and
immunohistochemistry.
