Giant cavernous hemangioma of the left atrial appendage: a case description and literature review

[摘要] In 2015, the World Health Organization (WHO) proposeda new histological classification of cardiac tumors. Cardiactumors are divided into the following: (I) benign tumorsand tumor-like conditions, (II) tumors of uncertainbiological behavior, (III) germ cell tumors, (IV) malignanttumors, and (V) tumors of the pericardium (1,2). Clinically,primary cardiac tumors (PCTs) are rare entities, and cardiachemangiomas (CHs) are particularly rare benign vascularlesions, accounting for approximately 5–10% of benigncardiac tumors and less than 2% of all heart neoplasms (3,4).CHs occur as a result of abnormal dilation or hyperplasia ofsmall arteries, veins, or capillaries (5), and are histologicallydivided into capillary hemangioma, cavernous hemangioma,and arteriovenous malformation (1,2).
