title: Low-grade osteosarcoma of the ethmoid sinus.
abstract: Osteosarcoma uncommonly arises in craniofacial bones and has only rarely been reported to arise in the ethmoid sinus. Most primary osteosarcomas arising in paranasal sinuses are high-grade malignancies. A low-grade osteosarcoma arising in the ethmoid sinus has not previously been described. We report the clinical, radiological and histological findings of a case of low-grade (parosteal osteosarcoma-like) osteosarcoma which arose in the ethmoid sinus.
