Where is one of the most common locations of the head and neck chondrosarcoma?
Maxillary bone.
A large lytic-expansile cauliflower growth mass lesion with bone destruction and numerous polymorphic ossified and calcified foci axial and size with axial width up to 70 x 65 mm and height up to 60 mm in left maxillary bone extended within left orbital and nasal cavity is seen which is also bulged within the left cheek and buccal space and also retromaxillary and pterygopalatine fossa. The mass compressed the left eye onto the left orbital roof and also extended within the left zygoma bone body and maxilla alveolar process, and infratemporal fossa.
The right eye has no native lens and has exodeviation. Small calcified focus in the anterior temporal side uveo-scleral layer of both eyes in the insertion of lateral rectus muscle tendon is seen.
