Cardiac Papillary Fibroelastoma, an Unusual Localization in an Asymptomatic Patient with Lieberkühn Type Adenocarcinoma of the Rectum: A Case Report

Cardiac papillary fibroelastoma is histologically a benign endocardial neoplasm. Though CPF has long been reported as the second most common primary cardiac neoplasm, it has since been pulled ahead of cardiac myxomas, largely due to evolving cardiac imaging modalities. We present a case of CPF originating from an unusual localization; the junction of the posterior mitral valve and endocardium of the left ventricle measuring 15 x 20mm, which was detected by a routine pre-evaluation transthoracic echocardiography before chemotherapy and treated by surgical mass excision in an asymptomatic female patient diagnosed with a Lieberkühn type adenocarcinoma of the rectum with a locoregional extension.
