Coronary and atrial compression by a giant cardiac hemangioma

Atrial Hemangioma: A Case Report and Review of the Literature

A primary cardiac tumor is a rare clinical entity which was reported an incidence of 0.03% in previous autopsy series. 75% cardiac tumors are cardiac myxoma and cardiac hemangiomas constitute only 1–2% of primary cardiac tumors. With the development of modern medical imaging technology and the enhancement of people’s health awareness, more and more asymptomatic cardiac hemangiomas were found and confirmed eventually. Here, we described a case of a 71-year-old man, who was hospitalized with intermittent palpitation for 1 year and a large mass of the heart was removed successfully via sternotomy which was confirmed as atrial hemangioma by postoperative histopathology. Furthermore, a comprehensive review of atrial hemangioma was conducted to date and a few recommendations for the diagnosis and treatment of this uncommon disorder were provided for clinicians.

Epithelioid Hemangioma (Angiolymphoid Hyperplasia With Eosinophilia) of the Heart With Peripheral Eosinophilia and Nephrotic Syndrome

Epithelioid hemangioma (EH) is a rare benign vascular lesion, characterized by endothelial cells with epithelioid/histiocytoid appearance. Heart involvement is extremely rare. We present an unusual case of cardiac EH in a young woman with supraventricular arrhythmia, nephrotic syndrome (membranous glomerulopathy), and peripheral eosinophilia after a pregnancy and normal partum resembling Kimura disease. Echocardiogram showed a large tumor mass in the right cardiac ventricle. The cardiac tumor was removed and the histopathology revealed an endothelial proliferation associated with abundant eosinophils. The neoplastic endothelial cells were eosinophilic and polygonal with epithelioid/histiocytoid morphology. Lymphoid nodules were occasionally seen. The neoplastic cells were positive for CD34, CD31, ERG, and factor VIII and negative for CK. A diagnosis of EH was rendered. The patient was alive and well after surgical resection. EH and Kimura disease represent separate entities, but clinical and/or histological overlapping can be observed. Epithelioid/histiocytoid endothelial cells constitute the hallmark feature that favors a final diagnosis of EH.
