Abstract

Conventional osteosarcoma, a subgroup of intramedullary osteosarcoma(OS) ,is the most common osteosarcoma that occurs in adolescents and early adulthood. We present a case of 22‑year‑old male patient with the chief complaint of proptosis, pain and swelling in the left orbital region & diagnosed as chrondoblastic osteosarcoma(COS) of left orbital bone. COS is very rare at orbital location, this report aimed to discuss clinical, radiographic, histopathologic, IHC findings and diagnostic pitfalls & manangement of COS in view of the literature.
