Chondrosarcome mandibulaire: à propos d’un cas et revue de la littérature

Abstract

Les chondrosarcomes sont des tumeurs cartilagineuses malignes à localisation maxillaire rare. Ils sont caractérisés par une évolution généralement lente dans le temps et par une tendance élevée aux récidives locorégionales après traitement chirurgical. Leur pronostic médiocre dépend de leur degré de différenciation et de la qualité de résection. Les auteurs rapportent un cas clinique de chondrosarcome mandibulaire et précisent les particularités épidémio-logiques, diagnostiques, thérapeutiques et évolutives de ces tumeurs. Mots clés Chondrosarcome · Mandibule · Tumeur cartilagineuseAbstract Chondrosarcoma is a malignant cartilaginous tumor rarely found in the jaw bone. Tumor progression is slow with strong propensity to recurrence after surgical removal. The prognosis is poor and depends on the degree of differentiation and the quality of resection. We report a case of mandibular chondrosarcoma and discuss the epidemiology, diagnosis, treatment, and follow-up of these tumors.

A Case Report of a Mesenchymal Chondrosarcoma of the Mandible

“…For some authors, there is a male predominance and for others both sexes are equally affected [2]. Its evolution is generally slow in time with a high tendency to locoregional recurrence after surgical treatment.…”

“…Metastasis is common, with diffusion occurring more often by the hematogenous way than by the lymphatic way. The lung and bone are the preferred sites [2].…”

“…It is a cartilage malignant tumor characterized by the formation of the cartilage by tumor cells. It represents 11% of all malignant bone tumors [2]. Localization at the head and neck is rare; about 5%; and the mandibular region of the mesenchymal type is exceptional.…”

“…These rare tumors most often affect young people in their second or third decade [4]. Their poor prognosis depends on their degree of differentiation and the quality of resection [2]. Treatment consists essentially of complete resection.…”
