Breast carcinoma metastases in paranasal sinuses, a rare occurrence mimicking a primary nasal malignancy. case report.
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.
