Solitary fibrous tumor of the larynx: a case report and review of the literature.

Solitary fibrous tumors are relatively rare mesenchymal neoplasms that were originally described as pleural- or peritoneal-based lesions. Although they were considered a form of mesothelioma, subsequent investigation failed to reveal mesothelial differentiation. Characterization of their histologic and immunohistochemical features, as well as identification in a multitude of nonmesothelial-based locations has further served to distinguish these lesions from the more diffuse and aggressive mesothelioma. Reports of solitary fibrous tumor in the larynx are extremely rare. We report a case of solitary fibrous tumor of the larynx in a 38-year-old man.
