Osteosarcoma of the mandible: A case with a clinical appearance similar to benign lesions

A 34-year-old woman with complaints of mandibular swelling that started 4 months earlier was referred to the Oral Diseases Department. Based on the clinical and radiographic appearance, the primary diagnosis was an intraosseous reactive lesion. However, the result of histopathology indicated osteosarcoma.

Osteosarcoma (osteogenic sarcoma) of the jaws presenting in general dental practice - a series of four cases

Introduction Osteosarcoma is the most common primary malignant bone tumour, usually arising in the long bones, with occurrence in the head and neck accounting for 8% of all osteosarcomas. Clinical features include swelling, pain, facial dysesthesia and abnormal mobility of teeth. Treatment consists of a combination of surgery, radiotherapy and chemotherapy.Case series Here, we present four cases of osteosarcoma of the jaws - two maxillary and two mandibular. All cases were initially assessed in the dental primary care setting before being referred for specialist opinion.Discussion The purpose of this paper is to present an overview of an uncommon but serious disease which can mimic common life-threatening dento-facial conditions. We discuss the diagnostic features, with an overview of clinical, histopathological and radiographic features.Conclusion These cases are important reminders of the potential clinical and radiographic appearance of a rare cause of facial swelling, and highlight the role of the general dental practitioner in early diagnosis and referral.

Early Diagnosis: A Seeming Misfortune for Osteosarcoma of Mandible-Rare Case Report

Osteosarcoma is a mesenchymal malignant tumour of long bones; it is the second most common malignancy of bone after multiple myeloma but it rarely affects jaw, accounting only for 4-8% of all osteosarcomas (Baumhoer et al. in Oral Oncol 50(2):147-153, 2014). The rare occurrence of tumour makes it challenging to diagnose either by radiographic or histopathologic examination. Here we presented a rare case of chondroblastic variant of osteosarcoma of body of mandible in a 54 year old female.

Custom facial reconstruction for osteosarcoma of the jaw

Osteosarcoma accounts for most primary bone cancers in children and young adults. High-grade lesions are typically managed with a combination of chemotherapy and wide-margin surgical excision. Although this malignancy typically affects the metaphyseal region of long bones, it also can be seen in the axial skeleton. Of axial locations, tumors in the head and neck can be particularly troubling to treat. Segmental bone loss after resection of malignant mandibular tumors continues to present important challenges to the reconstructive surgeon. Recent advancements in 3-dimensional modeling have facilitated custom templates for patient-specific reconstructions. This report describes the case of a young woman with osteosarcoma of the mandible undergoing customized template composite facial reconstruction using a vascularized osteoseptocutaneous fibula flap.

Osteosarcoma of the mandible: A case report with an early radiographic manifestation

Osteosarcoma is a classical malignant bone-forming neoplasm which usually presents with an aggressive clinical course. The current case is presented with the radiographic feature of widening of the periodontal ligament space of the involved teeth, which is considered to be the earliest radiographic manifestation of osteosarcoma involving the jaw bone. The main aim of this case report was to focus on the importance of early diagnosis of this tumor based on clinical and radiographic examinations, and confirmation by histopathology. Considering the rarity of the disease type and particularly taking into account the fast progression and aggressiveness of this neoplasm, it is clear that the presentation of a clinical case represents a major contribution to better understanding of osteosarcomas involving the jaw bone.
