In Sub-Saharan Africa, the association of polyadenitis and febrile syndrome, after excluding tuberculosis and lymphomas, must raise the suspicion of rare diseases such as Kikuchi-Fujimoto disease.

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.

Laryngeal chondrosarcoma is a rare malignant tumor that arises from the cartilaginous structures of the larynx. It is a slow-growing neoplasm with high tendency to locoregional recurrence after treatment. Surgery is the primary treatment. Prognosis depends on histological differentiation degree and quality of surgical excision which can be very mutilating. Distant metastatis can occur in cases of histological high-grade tumors. From a new observation and a review of the literature, we discuss the clinical characteristics, therapeutic modalities and patient outcomes.
