A rhabdomyoma is a benign tumor of striated muscle. Rhabdomyomas may be either cardiac or extracardiac (occurring outside the heart). Extracardiac forms of rhabdomyoma are sub-classified into three distinct types: adult type, fetal type, and genital type. Cardiac rhabdomyomas are the most common primary tumor of the heart in infants and children.
The mass size can obstruct blood flow or interfere with cardiac valve function and produce symptoms of heart failure. A tumor that invades the heart walls may cause arrhythmias, heart block, or pericardial effusion with or without tamponade. Tumors that invade adjacent lung tissue may cause pulmonary symptoms that mimic bronchogenic carcinoma. [6]
Myxoma is a rare, benign stromal tumor of mesenchymal origin often confused with other conjunctival stromal tumors. Conjunctival myxomas are thought to originate in Tenon's capsule and can masquerade as conjunctival lymphoma, lymphangioma, ocular surface squamous neoplasia (OSSN), or amelanotic melanoma.

Most heart tumors begin with myxomas, fibromas, rhabdomyomas, and hamartomas, although malignant sarcomas (such as angiosarcoma or cardiac sarcoma) have been known to occur. In a study of 12,487 autopsies performed in Hong Kong seven cardiac tumors were found, most of which were benign. [ 1 ]
Some benign tumors are able to grow to a dangerous size because unlike other cells, “tumor cells have found a way to evade the normal life and death cycle of a cell — meaning they’ve learned ...
This benign tumor made by connective tissue and fibroblast is largely observed in the ventricles of the heart. [2] The left ventricle is the most common location of cardiac fibroma and accounts for approximately 57% of cardiac fibroma cases followed by the right ventricle with 27.5% of cases. [1]
The tumor weighed more than 1.5 pounds, which is, according to Northwestern Medicine, double the weight of an average heart and was completely covering DiLillo's heart.
A heart attack happens when an artery that sends blood and oxygen to the heart is blocked, the Mayo Clinic says. It can cause a range of potential symptoms, including chest pain that can feel like ...
