title: Unusual left atrial appendage mass: atypical presentation of papillary fibroelastoma.
abstract: Papillary fibroelastomas are small, histologically benign neoplasms that are typically found on the valvular endocardium. We report a patient with a papillary fibroelastoma in an unusual location: the left atrial appendage. Although the mass was visualized both by computed tomography (CT) and transesophageal echocardiography, the diagnosis was histologically confirmed after surgical excision.
