Nasal Osteogenic Chondrosarcoma: A Case Report

Abstract

BACKGROUND: Osteosarcomas and chondrosarcomas are the most common malignancies of the jaw bones. Nasal osteogenic chondrosarcoma is rarely reported.
OBJECTIVE: To draw attention to a rare tumour, osteogenic
chondrosarcoma.
METHODS: A middle-aged woman presented with a three month
history of nasal blockade and mucopurulent discharge. She was fully clinically evaluated including anterior rhinoscopy and plain radiograph.
RESULTS: Detailed history, physical examination and plain radiography showed features suggestive of antrochoanal polyp with differential diagnoses of sino-nasal and nasopharyngeal tumour. At emergency tracheostomy, examination under anaesthesia, meticulous nasal and nasopharyngeal tumour  clearance was done. Histopathological examination of the mass revealed osteogenic chondrosarcoma.
CONCLUSION: Though rare, osteogenic chondrosarcoma affects nasal bones. Clinically the tumour mimicks an antrochoanal polyp and is associated with the challenge of recurrence.
