Extraskeletal mesenchymal chondrosarcoma involving the heart: report of a case.

Extraskeletal mesenchymal chondrosarcoma is a rare tumor frequently arising in the meninges and lower limbs. We describe a case of mesenchymal chondrosarcoma involving the heart in a 39-year-old man who presented with fever, chest pain and shortness of breath. His clinical course was rapid, leaving insufficient time for a complete diagnostic work-up, and the patient died 2 months after the onset of symptoms.
