Chondrosarcoma of the Nasal Cavity and Paranasal Sinuses: A Rare Entity

Chondrosarcomas are slow-growing malignant tumors that originate in cartilaginous structures. They typically manifest in the head and neck region, with a preference for the maxillofacial skeleton, particularly the mandible and maxilla. However, chondrosarcoma of the sinonasal tract is exceptionally rare, and only few cases have been reported. This report details the case of a 43-year-old woman who incidentally discovered chondrosarcoma in the maxillary and ethmoid sinuses with nasal extension. Subsequently, the patient underwent surgery via a paralatero-nasal approach with adjuvant radiotherapy. The aim of this study was to describe the clinical findings, management, and outcome of sinonasal tract chondrosarcoma. The primary treatment for chondrosarcomas remains surgery, with a transnasal endoscopic approach offering a viable option for complete resection in select cases.
