Heart metastasis of extraskeletal myxoid chondrosarcoma.
Isolated, remote heart metastasis of myxoid chondrosarcoma is extremely rare. We present an unusual case of isolated remote metastasis of extraosseus myxoid chondrosarcoma from the right ankle region to the right ventricle, its clinical course, and treatment in a 46-year-old woman. Although heart biopsy done before the surgery revealed myxoma, histopathologic diagnosis of the heart tumor was confirmed after its surgical resection from the right ventricle. Nine months after the surgery the patient was doing well but, seven months later, she died in the local hospital because of global heart failure. On the autopsy, the only metastatic lesion found was in the heart. The pericardium and heart muscle were infiltrated with the tumor, whereas all other organs were free from malignant dissemination.
