Solitary fibrous tumours (SFTs) are unusual mesenchymal tumours that were first described as primary spindle-cell neoplasms of the pleura. These tumours have been described in many other locations, including the urogenital system, orbit, mediastinum, and upper respiratory tract. These tumours are generally benign in nature, however some of them can be locally invasive and have the potential to be malignant. Although about 12%-15% of them occur in the head and neck area, SFT of the nasal cavity and paranasal sinuses are extremely rare. We present a case of a solitary fibrous tumour arising from the right maxillary sinus in a 50 year old Chinese man.
