Abstract
Tumors of jaw are among the most uncommon of all types of neoplasms. Osteosarcoma of the jaw represents a distinct group of lesions from the common type often occurring in long bones, which rarely affects the anterior maxilla. A 43-year-old male patient with a previous history of dental losses in the anterior maxilla region and biopsy results without conclusive diagnosis for 18 months attended the oral medicine service complaining of an asymptomatic hard nodule in the anterior maxilla. An incisional biopsy was performed, and diagnosis was chondroblast osteosarcoma. The patient was referred to the oncologist and head and neck surgeon, received 3 cycles of chemotherapy with cisplatin and doxorubicin, maintained stable disease, and then underwent conservative maxillectomy. The surgical planning included the collaboration of the dental team, with installation of immediate removable maxillary obturator prostheses, allowing the patient more comfort postoperatively and improving in speech, swallowing, and esthetics.
