title: Maxillary osteosarcoma in a young patient undergoing postorthodontic treatment follow-up: the importance of ongoing oral examinations.
abstract: Osteosarcoma is a common primary malignant tumor in long bones; it generally occurs in young adults. It is considered infrequent in the head and neck regions, where it is usually associated with poor outcomes and rates of survival. From a histopathologic point of view, osteosarcomas are commonly classified as osteoblastic, chondroblastic, or fibroblastic, although several unusual microscopic subtypes have also been reported. The purpose of this article was to present a case report of a maxillary chondroblastic osteosarcoma involving the maxillary sinus and the maxilla of a young woman who was diagnosed during early postorthodontic treatment follow-up. Treatment, prosthetic rehabilitation, and follow-up details are provided. Most importantly, this patient shows the importance of complete and systematic oral examinations during any routine dental treatment.
