title: [Ethmoid metastasis of primary breast tumor].
abstract: Metastatic tumors to the paranasal sinuses are uncommon. Symptoms and imaging studies are non-specific and usually similar to primary neoplasms in this region. Histological study of the neoplastic tissue is essential in order to ascertain its origin. A case of breast adenocarcinoma that metastasized to the ethmoid sinus is reported and the literature is reviewed.
