Introduction: Solitary fibrous tumours (SFTs) of the nose and paranasal sinuses are extremely rare.These were originally described as neoplasms of the pleura originating from spindle cells. It is further sub-classified as a benign type of mesothelial tumour. Its occurrence in many extra pleural sites have been reported earlier, mainly in the liver, parapharyngeal space, sublingual glands, tongue, parotid gland, thyroid, periorbital region, and very occasionally in the nose and  paranasal sinus area.   Case Report: A ۲۸-year-old man with a ۶ month history of persistent progressive left nasal obstruction and watering of the left eye is reported. Further imaging by CT and MRI revealed a large, left-sided, highly vascular, nasal cavity mass (Fig ۱,۲,۳,۴) pushing laterally on the medial wall of the maxilla. The patient underwent a lateral rhinotomy, which proceeded with the excision of the mass. Histopathological analysis of the specimen was consistent with SFT.   Conclusion:  This case is reported to develop insights regarding diagnosis and management of such rare tumours.
