Background: Metastases to breast and axilla from extramammary sites areuncommon and have been reported in only ۲% of breast malignancies. Ovariancancer metastatic to breast and axillary lymph nodes is extremely rare and onlyaccounts for ۰.۰۳%-۰.۶% of all breast neoplasms. The most common histologicfeature of ovarian cancer metastatic to breast is papillary serous adenocarcinoma.Differentiating the secondary breast malignancies from primary ones is crucial asthe treatment and prognosis are different, which could avoid many unnecessaryprocedures. Prognosis is generally poor because most patients have simultaneousspread of the disease. Case presentation: A ۶۷-year-old woman with a history of ovarian cancer,undergoing chemotherapy presented with redness and swelling in her left breastand pathologic axillary lymph nodes. Work ups revealed ovarian cancermetastases to breast and axillary lymph nodes. She underwent chemotherapy withsecond line chemotherapeutics. The results were satisfying and the patient is well. Conclusion: The history of cancer in patients with a breast mass, even ifclinically benign, may give rise to potential metastases. Screening with physicalexamination and serial mammography for patients with ovarian cancer could bebeneficial. Early and accurate diagnosis of breast metastatic tumors is critical forproper management and preventing unnecessary and possibly harmful procedures.
