Neoplastic Embolization from Cardiac Papillary Fibroelastoma with Unusual Presentation: A Case Report.

Papillary fibroelastoma is the second most frequent primary tumor of the heart. We report the case of a cardiac papillary fibroelastoma, arising from the interatrial septum, symptomatic from distal embolization to lower limb arteries. Such a clinical presentation is extremely infrequent for cardiac papillary fibroelastomas. Moreover, the site of origin not from cardiac valves and the pathogenetic mechanism underlying the clinical manifestation both represent peculiar additional findings of our case.
