Background: Chondrosarcoma is a malignant neoplasm characterized by the production of a cartilaginous matrix.
Case report: We present the case of a 58-year-old male patient referred to the maxillofacial surgery and traumatology service due to swelling in the posterior region of the right maxilla, with a duration of 8 months, and a previous history of a fibro-osseous lesion in the region. Intraoral examination revealed a rounded lesion with ulceration, firm upon palpation, in the area of teeth 17 and 18. The panoramic radiograph revealed a radiopaque lesion with a flocculated pattern in the right maxilla, and computed tomography showed a hyperdense lesion containing hypodense areas. Histopathological analysis revealed the presence of immature cartilage, with rounded neoplastic cells, nuclei of varied sizes, and intense pleomorphism, leading to a diagnosis of chondrosarcoma. The patient underwent surgical resection followed by radiotherapy and, after one year of follow-up, has shown no signs of recurrence.
Conclusions: Although rare in gnathic bones, chondrosarcoma should be considered in the differential diagnosis of osseous enlargement in this region.
期刊介绍：
Head & Neck Pathology presents scholarly papers, reviews and symposia that cover the spectrum of human surgical pathology within the anatomic zones of the oral cavity, sinonasal tract, larynx, hypopharynx, salivary gland, ear and temporal bone, and neck.
The journal publishes rapid developments in new diagnostic criteria, intraoperative consultation, immunohistochemical studies, molecular techniques, genetic analyses, diagnostic aids, experimental pathology, cytology, radiographic imaging, and application of uniform terminology to allow practitioners to continue to maintain and expand their knowledge in the subspecialty of head and neck pathology. Coverage of practical application to daily clinical practice is supported with proceedings and symposia from international societies and academies devoted to this field.
Single-blind peer review
The journal follows a single-blind review procedure, where the reviewers are aware of the names and affiliations of the authors, but the reviewer reports provided to authors are anonymous. Single-blind peer review is the traditional model of peer review that many reviewers are comfortable with, and it facilitates a dispassionate critique of a manuscript.
