Osteochondroma (OC) is one of the most common benign neoplasms which usually develops in long bones (arise from the metaphyseal ends of long bones) and very rarely occurs in craniofacial region.

An osteochondral neoplasm of the soft tissue, an uncommon lesion of uncertain pathogenesis, usually arises from the synovial tissue in joints and tendon sheaths. Rarely, extra-skeletal OCs also arise outside of synovial compartments. Since the etiology of OC remains controversial the diagnosis of extra-skeletal OC should be considered when a discrete ossified mass is localized in the soft tissue. Here A case of pathologically proven Para-articular soft tissue Osteochondroma is presented together with clinical and radiologic findings. The unique feature of this case is that it's a rare subtype of soft tissue chondromas occurring in and around the joints.
