Multifocal Ancient Thoracic Schwannomas: A Case Report and Review of Literature

Abstract

Primary pleural schwannoma is a rare benign tumor of the thorax. Because of their gradual progression, they are generally asymptomatic. Herein, we report a 53-year-old male patient with a well-circumscribed mass located at the right lower lung field. He was totally asymptomatic. His contrast-enhanced computerized tomography scan showed a round, well-defined, inhomogeneous, mildly-enhancing lesion with a few small internal speckle calcifications arising from the pleura along the right lateral sixth intercostal space, measuring about 5.5 4.2 cm in diameter, and another smaller lesion at the left apical hemithorax. Both masses were resected successfully under video-assisted thoracoscopic surgery. Histopathologic analysis revealed alternating areas of compact spindle cells and hypocellular areas and degenerative changes of blood vessels inside. Thus, the diagnosis of multifocal ancient thoracic schwannomas was established.
