Sinonasal carcinoma: A rare case report.

Carcinoma of the nose and paranasal sinuses is an uncommon tumour accounting for less than 1% of all malignancies and about 3% of head and neck malignancies. It is more common in fifth and sixth decades with increased male preponderance. Occupational exposure to nickel has been known to increased its occurrence. Here we present a case of 25-year male presenting with right sided nasal blockage and pain in the right eye with swelling for 2 months. Imaging studies revealed a large soft tissue density with involvement of surrounding structures with bony erosion and extension to the orbit. Histopathology and Immunohistochemistry confirmed the diagnosis of poorly differentiated sinonasal carcinoma non keratinising type.
