title: Extraskeletal myxoid chondrosarcoma of the pleura. Report of a case clinically simulating mesothelioma.
abstract: A primary extraskeletal myxoid chondrosarcoma of the pleura that clinically mimicked a malignant mesothelioma in a 66-year-old man with a history of asbestos exposure is described. Although exceedingly rare in this location, the characteristic histologic features, immunohistochemical reactivities, and ultrastructural features support the diagnosis of extraskeletal myxoid chondrosarcoma. Many ferruginous (asbestos) bodies consistent with the exposure history were found in the lung tissue sections and confirmed by energy-dispersive spectrometry. This case demonstrates an unusual pleural primary neoplasm associated with asbestos.
