Chondroblastoma are rarer benign neoplasms arising from the epiphyseal ends of the long bones. Rarely these lesions can occur in the oral cavity.
CHONDROBLASTOMA CLINICAL FEATURES:
Age: Most of the patients are below the age of 25years.
Sex: Male people are affected more often than females.
Site: Intraoral chondroblastomas are usually rare and whenever they occur, mandibular condyle is the most favored site.
CHONDROBLASTOMA CLINICAL PRESENTATION:
- Chondroblastomas clinically present a relatively large, bony hard lesion, causing bulging of the jawbones.
- Displacement of the regional teeth often occurs.
- Pain may be present especially during palpation.
CHONDROBLASTOMA RADIOGRAPHIC FEATURES:
Radiographically Chondroblastomas usually present-a large radiolucent area in the bone, with well-defined margins.
There can be presence of few radiopaque foci within the radiolucent zone.
- Histologically chondroblastomas present a highly cellular structure consisting of numerous round or polyhedral ‘chondroblast-like’ cells within a thin fibrous tissue stroma.
- Within the fibrous stroma, few areas of calcification are seen, besides this, there can be presence of multiple multinucleated giant’s cells.
