ABSTRACT

Localized fibrous tumors of the pleura (LFTP) are rare, usually benign neoplasms of the pleura. This tumor has received many names including fibrous mesothelioma, benign mesothelioma, localized mesothelioma, subpleural fibroma, solitary fibrous tumor of the pleura, and LFTP, which reflect clinical and pathological characteristics of this tumor (1). Recently, the term fibrous tumor of the pleura has been preferred as it emphasizes its distinct separation from malignant mesothelioma. In contradistinction to LFTP, malignant mesothelioma is causally related to asbestos exposure, is usually diffuse in gross appearance, is of mesothelial origin and stains for cytokeratin, and is rapidly fatal. LFTP is the preferred description of this tumor rather than solitary fibrous tumors of the pleura (SFTP) because several reports have documented multiple LFTP within the same patient (2,3).
