Breast cancer is the first female cancer in Morocco and worldwide. The most common metastatic sites in breast cancer are the liver, bones, lungs and, less frequently, the brain. Metastases in genital tract are very rare, thus the literature reported a few cases. Case report: A 56 years old women, with family history (two sisters followed for breast cancer, a mother died of leukemia and the father died of liver cancer), was followed since 2007 for locally advanced and nonmetastatic breast cancer, she was treated initially by upfront chemotherapy then a total left mastectomy with homolateral axillary lymphadenectomy and then hormonotherapy (Tamoxifene). The follow up of our patient reveals multiple metastatic sites including the site of mastectomy, lymph nodes, the bone and a rare site wich is the uterine cervix. We are reporting this case to alert our hospital practitioners to the possibility of this association and the need for a full gynaecological examination and eventually a biopsy for all breast cancer patients. Conclusion: Any genital bleeding that occurs during the follow-up of patients on breast cancer's traitement should not be routinely linked to hormonotherapy. Our case draws our attention to the importance of gynaecological examination as part of breast cancer follow-up in order to detect metastases in the genital tract, even if they are extremely rare.
