Pathological (late) fractures of the mandibular angle after lower third molar removal: a case series.

Introduction: Pathological (late) fracture of the mandibular angle after third molar surgery is very rare (0.005% of third molar removals).

High-grade chondroblastic and fibroblastic osteosarcoma of the upper jaw.

Osteosarcomas (OS) are extremely uncommon in maxillofacial region (6%-10% of all sarcomas). Jaw lesions are diagnosed on average two decades later than sarcomas of long bone, with a peak incidence between 20 and 40 years. Head and neck OS (HNOS) are associated with a lower metastatic rate than long bone OS, and they have a better 5-year survival rate, ranging between 27% and 84%.
