Bilateral Solitary Fibrous Tumor of the Vocal Fold Mimicking Reinke’s Edema

Abstract

The solitary fibrous tumor (SFT) is an uncommon benign tumor, which is usually found in the pleura. Even though SFTs have been reported in various areas including the head and neck these days, laryngeal SFT is very rare, not to mention the bilateral vocal fold. Here, we report a new case of bilateral laryngeal SFT with a review of related literature. A 67-year-old male patient was admitted to our institution because of husky voice he experienced for several months. Endoscopic examination revealed a bilateral vocal folds swelling. The lesion was removed with CO2 laser under direct suspension laryngoscope. The pathological diagnosis was made by various immunohistochemical stainings including vimentin, Bcl-2, CD99 and CD34. During the 24 months follow-up after the surgery, there was no sign of recurrence.
