title: Maxillofacial metastasis from breast cancer.
abstract: Metastatic tumors to paranasal sinuses are exclusively rare. In this paper, we report a case of breast carcinoma metastasizing to the right maxilla. The metastasis occurred 5 years after radical mastectomy and presented as a primary sinonasal mass. The diagnosis was confirmed with histopathologic and immunohistochemical examination however the patient died before starting any specific treatment because of tumor bleeding.
