title: Synovial sarcoma of the heart arising from a so-called mesothelioma of the atrio-ventricular node.
abstract: A primary tumour of the right atrium with morphological, ultrastructural and immunohistochemical features of a synovial sarcoma is described. This appeared to have arisen from a benign so-called mesothelioma of the atrio-ventricular node and had metastasized to the lungs. The histogenesis and relationship of these two tumours are discussed.
