Chondrosarcoma is a malignous cartilage tumor, which rarely involves Head and Neck. The tumor mainly affects males during the third and fourth decades of life. In the face, it's often situated in the maxillary sinus and bone and rarely found in the nasal septum. In this study, we describe a thirteen-year-old patient who was admitted because of a right malar facial deformity unusually painful. On the physical examination we found a 3cm-length deformity in the left malar, associated with a normal anterior rinoscopy. In order to diagnose this deformity, the patient was submitted to a paranasal sinus computadorized tomography (CT), face magnetic resonance and a lesion biopsy, which initially revealed condroma. This mass was surgically excised and reappeared five months later. Because of this unusual phenomenon, we requested a lamina revision, which revealed Chondrosarcoma type 1. Therefore, a new surgery was performed objecting total tumor excision. In addition, the patient was sent to radiotherapy sessions. One year later from the last surgery, the patient is still assimptomatic without any sign of tumor regrowth. Chondrosarcomas are malignous slow growing tumors, but locally aggressive. As a matter of fact, they are very likely to regrow. The treatment is often surgery, since they are low radiosensitive and chemiotherapy is merely palliative. The objective of this study is to show a chondrossarcoma case in the maxillas, etmoid and sphenoid sinus and septum, discussing its clinical presentation, diagnoses, treatment and prognoses.
