abstract: Sinonasal neoplasms are rare and exceptional site for metastatic tumours and comprising <3 % of all malignant aerodigestive tumours and <1 % of all malignancies. Renal cell carcinoma is known to metastasise to the most unusual sites, the sinonasal region being one of them. We here by present a case of 60 year old male patient who presented with epistaxis and nasal obstruction. Clinical examination and CT scan revealed a tumour in the right nasal cavity and maxillary sinus. The presence of primary renal cell carcinoma was recognized only after surgical removal of metastatic tumour. Very few reports have been presented in literature of metastatic renal cell carcinoma in the sinonasal region. We present this case to document its occurrence; highlight the rarity, presentation and difficulties in diagnosis and treatment along with review of literature.
