title: Angiomatous variant of so-called mesothelioma of the atrioventricular node.
abstract: A case is presented of an elderly woman found to have an angiomatous tumor involving the atrioventricular (AV) node. The entire AV node was not involved, which explains her lack of symptomatology during her life. The divergent histologic patterns observed in these tumors suggest that the term AV node tumor is preferable to the term mesothelioma.
