Laryngeal solitary fibrous tumor treated with CO2 laser excision: case report.
The solitary fibrous tumor is an uncommon unilateral benign lesion that usually arises from the pleura. Recently, these tumors have been described in many other locations, such as the mediastinum, head and neck, orbit and urogenital system. To date, only two cases of solitary fibrous tumor arising from the larynx have been reported in the scientific literature. We describe a new case of laryngeal solitary fibrous tumor localized at the right false vocal fold. A 29-year-old man presented with a 6-month history of progressive hoarseness and foreign body sensation in the throat. A mass lesion was recognized in the right false vocal fold, and CT scan demonstrated a large, well-defined tumor without signs of infiltration. The tumor was removed by transoral CO(2) laser surgery. The definitive diagnosis was obtained by immunohistochemical analysis that showed vimentin and CD34-positive cells. The patient remains free of tumor after 15 months of follow-up.
