Sinonasal Chondrosarcoma, an Unusual Location

Abstract

Introduction: Chondrosarcoma is a tumour with a cartilaginous matrix frequently encountered in long bones and the pelvis with rare sinonasal location. Patient and methods: We report the case of a 25-year-old patient who was referred to us for an extension work-up for sinonasal chondrosarcoma confirmed by anatomopathological examination. Results: Facial magnetic resonance imaging (MRI) confirmed by a CT scan showed an osteolytic tumour process of the hard palate and walls of the left maxillary sinus that was locally advanced. Conclusion: The sinonasal location of a chondrosarcoma is rare. Characterized by cross-sectional imaging, confirmation was provided by histological assessment.
