ethmoidal osteosarcoma

Friday 6 November 2009

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 (parosteal osteosarcoma-like) arising in the ethmoid sinus has also been described.
