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.
Learning Points: The sinonasal location of a chondrosarcoma is rare.A slow-growing tumour with a cartilage matrix in adults, it is revealed mainly by neurosensorial signs and mass effect in its sinonasal location.Radiological characterization includes areas with a weak signal on T1- and T2-weighted images in MRI, not enhanced by gadolinium, corresponding to the cartilage matrix.

To study the feasibility and efficacy of pericranial flaps for the repairs of large anterior skull base defects. The average length of the pericranial flaps needed for skull base repair was determined with computed tomography measurements in 20 adults and anatomical dissections in 5 cadaver specimen. A series of patients who underwent endoscopic skull base surgeries and subsequent reconstructions with pericranial flaps at the Department of Otolaryngology Head and Neck Surgery, Shanghai Jiao Tong University School of Medicine Affiliated Sixth People's Hospital from 2016 to 2022 were retrospectively reviewed.

Sinonasal bone lesions encompass a diverse spectrum, ranging from nonneoplastic and benign conditions to aggressive, malignant neoplasms. These lesions can affect individuals across various age groups, from pediatric to adult patients. Recognizing these entities is crucial, given the variability in treatment approaches, recurrence rates, and prognoses.

Article Synopsis
- - Enchondromas are benign cartilage tumors that usually develop asymptomatically in the metaphysis and diaphysis of bones.
- - A rare case of a giant sinonasal enchondroma is presented, highlighting its uncommon location since few similar cases exist.
- - More research is necessary to better understand the malignancy potential of enchondromas, particularly in unusual sites like the sinonasal area.

A 14-y-old intact female llama () was presented for evaluation of a right maxillary swelling of 3-mo duration. Clinically, the animal had mild nasal discharge, abnormal retropulsion of the right eye, and moderate gingival disease. An incisional biopsy of the maxillary mass revealed pleomorphic and mitotically active neoplastic spindle-to-stellate cells organized in haphazard lacunae embedded in abundant chondroid matrix.
