Myxoid Chondrosarcoma of Nasomaxilloethmoid Region with Intracranial Extension

Abstract

Chondrosarcoma of the faciomaxillary area constitute only 4 % of non-epithelial tumours of the nasal cavity, paranasal sinuses and nasopharynx, making it one of the rare malignancy (Indian J Otolaryngol Head Neck Surg 60(3):284–286, [1]), with its myxoid variety still rarest. It is a slow-growing tumour, occurring mostly in middle-aged men. Primary chondrosarcoma of the nasal and paranasal sinus region, including the nasal septum, rarely extends into the cranial or intracranial areas unless there is recurrence (Indian J Ophthalmol 41(4):189–191, [2]. When it does occur, early diagnosis is difficult because patients generally present with common, nonspecific sinonasal complaints. A 45 year male patient came to ENT OPD with complaints of epistaxis, diplopia, facial swelling and loosening of teeth. On examination extensive swelling was present involving right maxilla, palate and ethmoid with shifting of Rt eye laterally. FNAC of swelling was non specific infected cystic lesion. On endoscopic examination there was erosion of Rt lateral wall of nose with mucoid material filling maxilla. Its wall was expanded & lined with velvety red mucosa. Maxillary antral biopsy report was myxoid chondrosarcoma. CT scan revealed extensive lesion of maxilla, ethmoid going up to optic nerve and brain. This case of myxoid chondrosarcoma is presented as it is a rare diagnosis. It presented with advanced disease involving nasomaxilloethmoid region and extended up to optic canal and middle cranial fossa. In a thorough review of Indian literature this was a rarely diagnosed tumour.
