Low-grade osteosarcoma of the ethmoid sinus.
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.
