Primary chondrosarcoma of ethmoid bone in a 6-year-old child.
Chondrosarcoma (CS) is a distinctly uncommon tumor in young patients and tends to be located in the extremities. Cartilaginous tumors in young patients are benign tumors. We report a case of a childhood CS in a 6-year-old boy who presented with right-sided proptosis. Radiological examination revealed a large destructive mass in right ethmoidal sinus extending into the surrounding sphenoidal sinus, intracranially, and the into right orbit, causing proptosis. Biopsy of the mass showed characteristic features of a well-differentiated CS. There are no reports of CS presenting as proptosis and arising from ethmoid bone. This case highlights the rarity of this tumor with regard to age of presentation and site of origin.
