​Pathology - Osteochondroma

​Pathology - Osteochondroma 
arises from the growth plate's lateral portion being displaced, which causes the bone to proliferate away from the long axis.
The most frequent benign tumor of the bone is osteochondroma.
Most frequently observed in guys under 25.

Gross: Usually appears in the tibia or femur metaphysis; a cartilage cap protrudes from the bone to cover the growing stalk of the bone.
Microscopic: Hyaline cartilage covers the freshly produced bone that results from endochondral ossification, which covers the medullary cavity that forms the stalk's core.

frequently asymptomatic and found by accident on radiographs; if symptomatic, it may show up as a mass or pain from a stalk fracture, nerve impingement, or irritation of the soft tissue around the mass; in rare cases, it may progress to chondrosarcoma.
Imaging: Radiographs show the growth of the bone stalk.

Surgery in case of symptoms.

several hereditary exostosis is an autosomal dominant disorder in which there are several osteochondromas.
Benign tumors originating from osteoblasts include osteoid osteoma and osteoblastoma. Osteoblastomas typically originate in the spine, whereas osteoid osteomas typically start in the femur or tibia.
The most prevalent symptom of these lesions in men under 25 is bone discomfort.
