Solitary Diaphragmatic Metastasis of a Previously Excised Chest Wall Chondrosarcoma.

Chest wall chondrosarcomas are relatively infrequent tumours. Diaphragmatic metastasis are rarer still, and are generally associated with disseminated disease, usually involving the liver and the lungs. The authors present the case of a 65 year old man with a prior history of a chest wall chondrosarcoma, which on a routine chest CT was identified a single diaphragmatic metastasis. A redo thoracotomy was performed, with partial resection and reconstruction of the diaphragm. The post-resection histopathological examination revealed a conventional chondrosarcoma metastasis, centred in the diaphragmatic muscle, not reaching the pleura or the peritoneum.
