Metastatic osteosarcoma of the ethmoid: an unusual cause of recurrent epistaxis and proptosis

Abstract

Osteosarcoma is the most common primary malignant tumour of bone and it usually metastasises to the lung. In the nasal cavity metastatic disease is extremely rare. We describe a case of osteosarcoma presenting with recurrent epistaxis, and proptosis due to secondaries in the nasal cavity. To our knowledge such a case has not been reported previously in the available English literature.
