RESUMO
Chondrosarcoma is a malignant cartilaginous tumor that rarely occurs in the maxillofacial bones. A 44-year-old woman complained about swelling and mild pain during mastication in the right parasymphysis region. Clinical and radiographic examinations revealed characteristics of osteosarcoma. A microscopic examination revealed an abundant proliferation of malignant neoplastic cartilage cells of varying sizes arranged as immature tissue and the absence of an osteoid matrix. This article presents a case of chondrosarcoma of the jaw and discusses the differences between osteosarcoma and chondrosarcoma.

According to the World Health Organization, hemangiomas are benign vasoformative neoplasms or developmental conditions of endothelial origin. The body region is the most commonly affected part of the mandible, and only 4 cases of condylar tumors have been reported in the literature to date. The differential diagnosis between high and low flow vascular lesions is crucial for successful treatment, decreasing the occurrence of serious intraoperative hemorrhage. The clinical, radiographic, and pathological features of an intraosseous vascular lesion in the mandibular condyle in a 22-year-old male are presented, and the differential diagnostic aspects between hemangioma, vascular malformation, and high or low flow lesions are discussed.
