Metastatic tumours to the paranasal sinuses are an exceedingly rare event, the large majority being of renal origin. Herein, a case of metastatic breast carcinoma to the right maxilla is described which occurred 4 years after radical mastectomy, clinically and radiologically presenting as a primary sinonasal mass. Only the histopathologic examination together with a broad spectrum of immunohistochemical antibodies were useful in confirming the origin of the neoplasm.

Abstract
Metastatic tumours to the paranasal sinuses are an exceedingly rare event, the large majority being of renal origin. Herein, a case of metastatic breast carcinoma to the right maxilla is described which occurred 4 years after radical mastectomy, clinically and radiologically presenting as a primary sinonasal mass. Only the histopathologic examination together with a broad spectrum of immunohistochemical antibodies were useful in confirming the origin of the neoplasm.
