Abstract

Cardiac papillary fibroelastoma (CPF) is a valvular tumor that may be mistaken for infective endocarditis (IE). We describe a case of CPF complicated by Coxiella burnetti IE. According to Duke's criteria, a diagnosis of IE was repeatedly considered as excluded or established during the clinical course, highlighting the criteria limitations.

Keywords: Coxiella burnetti; Endocarditis/diagnosis; Infective endocarditis; Papillary fibroelastoma; Primary cardiac tumor.

Cardiac papillary fibroelastoma: pathological findings. Histopathological findings: Hematoxylin & eosin[H&E] stained sections: A. (×40) A papillary mass showing numerous arborizing papillary fronds arising from a common central stalk continuous with that of the valve leaflet. B. (×100) The papillae consist of central cores of hyalinized stroma (*avascular, dense, fibrotic connective tissue, with almost acellular collagen). The fronds are coated by a single endothelial layer (arrows).
