Chondrosarcoma in the mental foramen region of the mandible: A case report

Chondrosarcoma is a malignant tumor that is characterized by the formation of cartilage by tumor cells. The tumor is commonly observed in regions where cartilage is already present. In total, 5-12% of chondrosarcomas occur in the head and neck region. However, the occurrence of chondrosarcoma in the mental foramen region is extremely rare. The aim of the present study was to report a case of chondrosarcoma in the mental foramen region. An 18-year-old man presented with a 3-month history of a painless mass over the labial aspect of the right mandible, which was associated with the patient feeling unwell and the loosening of the lower anterior teeth. The patient underwent segmental mandibulectomy and the final pathological diagnosis was chondrosarcoma. Following mandibulectomy, the patient continued to receive routine follow-up. In addition, the present study reviewed the literature concerning chondrosarcomas in the head and neck region.
