Sarcomatous mesothelioma in the left ventricle: A rare entity

Abstract

Mesotheliomas are malignant tumors of the pleural and peritoneal surfaces. They occur occasionally in the pericardium and atrioventricular node in the heart. To our knowledge, mesotheliomas originating from the left ventricle are rare. A case of a large malignant mesothelioma arising from the ventricular septum in the left ventricle is presented, which was treated by surgical resection.

Two-Chamber Intracardiac Mesothelioma

“…1–2 An extremely rare incidence of primary unichamber intracavitary cardiac mesotheliomas correspond to scarce reports in the literature. 3 Masses involving the mitral valve can have both a ventricular and an atrial aspect, and this may have existed to some extent with these previous reports. However, this is the first report to date describing an intracardiac mesothelioma extending throughout two chambers in the left heart, running from the left atrium to the papillary muscles.…”

Sarcomatous Pleural Mesothelioma Metastatic to Left Ventricular Endocardium

“…1,[7][8][9] Endocardial involvement is rare. 1,7,10 This case report describes a patient with pleural mesothelioma who developed metastasis to the left ventricular endocardium without evidence of invasion of pericardium or myocardium.…”
