Breast metastasis of cervical cancer: A case report and systematic literature review

Abstract

It has been reported that extramammary malignant tumors metastasize to the breast, but cervical cancer metastasis to the breast is very rare. At present, there are only dozens of reports about cervical cancer metastasis to breast in the world. It is difficult to distinguish between primary breast cancer and metastatic breast cancer. We report a 44-year-old woman who underwent surgery, chemotherapy, and radiotherapy for cervical cancer 5 years ago. Then, she was hospitalized for finding a left breast mass measured 2.9 × 2.7 cm in chest CT. Pathological examination combined with immunohistochemical staining showed that the mass came from the cervix. Then, the patient received systematic chemotherapy and interstitial brachytherapy (IB) for the breast mass and got a great result. Cervical cancer rarely metastasizes to the breast. In this case, we confirmed the diagnosis of breast mass by histopathological examination and immunohistochemistry. IB achieved a good result in the treatment of the breast mass. We hope to provide reference of prognosis and treatment when facing this situation by presenting this case.

Breast metastases from extra-mammary cancers: A report of 3 challenging cases and literature review

“…Imaging presentations of these metastases are also nonspecific, although the presence of multiple lesions can aid in diagnosis [1] .…”

“…Secondary breast locations for extra-mammary tumors account for approximately 0.5%-6.6% of all breast cancers [1] . These secondary tumors can originate from a wide variety of primary sites, with the most common being melanoma, hematologic malignancies (leukemia and lymphoma), ovarian carcinoma and pulmonary carcinoma [2 , 3] .…”
