title: Recurrent malignant sino-nasal solitary fibrous tumor: Eliminate the enemy at the first instance.
abstract: Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms that usually arise in the pleura or less commonly in relation to other serosal surfaces. Infrequent case reports of extra-pleural SFTs have been described at various sub sites within the head and neck area. We report a case of recurrent sino-nasal SFTs treated with surgery followed by re-excision and adjuvant radiation on recurrence and then salvage chemotherapy on progression. Further discussed are the challenges associated with accurate histological and immunohistochemical diagnosis, the difficulty in assessing the aggressiveness and malignant potential of these lesions and the appropriate treatment and follow-up duration that these neoplasms require. To the best of our knowledge this is the first reported case of recurrent malignant sino-nasal SFT in available scientific literature in English language.
