Osteosarcoma is a very uncommon tumor of the maxillofacial region. Due to the occurrence of the tumor at a young age and its aggressive nature, radical surgery forms the only modality of treatment. A combination of radiotherapy and postoperative chemotherapy has been used for the management of this tumor. A case report of osteosarcoma of the posterior maxilla in an adolescent with a 1-year disease-free follow-up is presented in this report.

Cementoblastoma is a benign odontogenic mesenchymal tumor characterized by cementum production. Cementoblastoma is considered a relatively rare neoplasm with a predilection to the posterior region of the mandible. The main clinical differential diagnoses include hypercementosis, cemento-osseous dysplasia, condensing osteitis, idiopathic osteosclerosis, osteoblastoma, odontoma, and osteosarcoma.

Background: Osteosarcoma of the jaws is a rare primary malignant tumor of bone. The clinical, radiological and histopathological features of a case associated with cemento-osseous dysplasia is presented.
Case Report: A 57-year-old mixed-race female presented with a large, progressive, swelling of the right mandible.
Introduction: conventional parosteal osteosarcoma is an uncommon malignant bone tumor, comprising 4% of all osteosarcomas. Although rare, parosteal osteosarcoma is the most common type of osteosarcoma of the bone surface. We present the clinical, histological and imaging characteristics of a rare histologic variant of a parosteal osteosarcoma, review the literature and emphasize the importance of radio-pathological correlation as well as the interpretation of a representative biopsy in order to obtain the correct diagnosis.

Background: Scoliosis is one of the long-term consequences of surgical resection of pediatric chest wall tumors. This study aimed to identify the risk factors associated with scoliosis development following the resection of chest wall tumors.
Methods: Retrospective cohort study of 64 children who underwent resection of malignant chest wall tumors from 2009 to 2022.

Introduction: Extra-articular hip resection may be necessary in cases of malignant tumour of the pelvic bone or of the proximal femur invading the hip joint. When the tumour is in the proximal femur, it is possible to resect the acetabulum en bloc by performing a periacetabular osteotomy, but this creates a discontinuity in the pelvic ring with difficult reconstruction and diminished function. Several techniques described recently seek to be as sparing as possible on the pelvic bone by preserving the posterior column or both columns in order to facilitate reconstruction and improve function.
