Chondrosarcoma of Nasal Cavity: a Rare Entity

Sino-nasal low-grade chondrosarcoma revealed by isolated bilateral loss of sight: an unprecedented presentation of a rare tumour

Chondrosarcomas are malignant cartilage-forming tumors representing less than 0.1% of all head and neck malignancies, and nasal cavity is an exceptional location among them. Clinical presentation could be consisting of either rhinological signs or asymptomatic endonasal mass. None of the previous reports mentioned ophthalmological symptoms at the forefront of the initial presentation. We report a case of sino-nasal low-grade chondrosarcoma in a patient who presented initially with isolated bilateral subtotal blindness, managed by endoscopic resection and adjuvant radiotherapy.

Rare case of nasal cavity chondrosarcoma presenting only with unilateral decreased vision

Chondrosarcomas comprise a heterogeneous group of malignant lesions characterized by production of cartilage matrix. Sinonasal involvement is extremely rare, with nasal congestion and obstruction being the leading symptoms. We present a rare case of large chondrosarcoma of the nasal cavity and paranasal sinuses, primarily presenting with ocular symptoms.

Increased 68Ga-FAPI Activity in Chondrosarcoma of Nasal Cavity

ABSTRACT

Chondrosarcoma is a rare entity tumor, which mainly appears in long bones and pelvic bones, but rarely in nasal cavity. Herein, we report the 68Ga-FAPI PET/CT findings in a 54-year-old man with chondrosarcoma of nasal cavity.
