Solitary fibrous tumor of the nasal cavity.

The solitary fibrous tumor (SFT) is a mesenchymal neoplasm first described by Klemperer and Rabin in 1931. It involves primarily the pleura, but has been described in the urinary bladder, limbs, thorax and abdomen, lungs, kidneys, prostate, meninges, mediastinum, and head & neck. In the head and neck, this tumor may involve the orbit, salivary glands, soft tissues, eyelids, mouth and nose, nasopharynx, retropharinx, oropharynx, and the thyroid gland. This study presents the fifth case of nasal SFT in the literature, the second in the Latin-American literature.
