Their evolution is generally slow in time. They have a high tendency for locoregional recurrence after surgical treatment. Their prognosis depends on their degree of differentiation and the quality of resection. The authors report a clinical case of mesenchymal mandibular chondrosarcoma (MC), which is considered to be a subtype of CS, and specify the epidemiological, diagnostic, therapeutic and evolutionary features of this tumor. Case Report: A 73-year-old woman reported in February 2018 in our department complained of a slowly enlarging mass involving the right part of the lower jaw for the last 18 months. On examination a firm multilobular painful mass was palpated with cortical expansion, occupying the right side. A CT scan with 3D reconstruction was achieved and showed osteolysis lesions and cortical thickening. The mass biopsy for histological examination found a grade I well-differentiated bone chon-drosarcoma. We performed a hemi-mandibulectomy with complete resection of the tumor. The anatomopathologic examination of the resection specimen was in favour of a grade II mesenchymal chondrosarcoma. No radiotherapy was needed. The patient’s follow up was uneventful. Discussion: CS grading is the key to its management. Low grade CS (grades I and II) of the facial skeleton are luckily the most common, they are best treated with a local resection using 1.5 cm margins for bone and soft tissue. According to published literature, CS was historically considered as a radio resistant tumor. Radiotherapy and chemotherapy were therefore mainly reserved for high-grade tumors and for non-operable lesions. However, radical local surgery appears to be the treatment of choice for low grade chondrosarcoma. Conclusion: CS’s definitive diagnosis depends on appropriate radiographic evaluation along with adequate biopsy with meticulous histopathological examination and adjunctive immunohistochimical analysis. Neither chemotherapy nor radiotherapy is indicated as primary treatment. A long period follow-up should be advised as recurrence and metastasis are very frequent. 展开更多
