Papillary fibroelastomas are rare and normally benign cardiac tumors typically attached to cardiac valves. This report describes two patients who were evaluated for intermittent dyspnea in one case and for the source of cerebral embolism in the other. In both patients transthoracic echocardiography revealed a pedunculated mobile mass adjacent to an atrioventricular valve, suggestive of papillary fibroelastoma. Postoperative histology was confirmatory of papillary fibroelastoma with a typical hyalinized hypocellular stroma covered by a single layer of endocardial cells.
乳头状纤维弹性瘤是一种罕见的通常为良性的心脏肿瘤，通常附着于心脏瓣膜。本报告描述了两名患者，一例因间歇性呼吸困难接受评估，另一例因脑栓塞来源接受评估。在这两名患者中，经胸超声心动图均显示出一个与房室瓣相邻的带蒂可移动肿物，提示为乳头状纤维弹性瘤。术后组织学检查证实为乳头状纤维弹性瘤，其具有典型的玻璃样变、细胞稀少的间质，表面覆盖单层心内膜细胞。
