Sandbox:differential myxoma

The table below summarizes the findings that differentiate Cardiac Myxoma from other conditions that cause emboli and hemorrhage:

Disease	Findings
Papillary fibroelastoma	Is a rare benign primary tumor of the heart that typically involves one of the valves of the heart. Presents with syncope, chest pain, heart attack, stroke and sudden cardiac death. They are the third most common type of primary tumor of the heart. There is a slightly increased male predilection.
Lipoma	Also known as "Lipomatous hypertrophy (LHIS)" is a very rare benign primary cardiac neoplasm. It is the proliferation of mature adipocytes. Lipomas are typically found in adult patients but can affect all ages. A common clinical feature is arrythmias.
Rhabdomyoma	Is the most common primary cardiac tumor in children. It is conformed from hamartomatous accumulation of the striated cardiomyocytes. Rhabdomyomas occur with more frequency in the myocardium of the left ventricle or in the interventricular septum. Is commonly associated with tuberous sclerosis, and congenital defects of the heart.
Thrombus	Intracardiac thrombi, can occur when there is an elevated risk of blood clots developing, such as: atrial fibrillation (atrial thrombi predominate), mitral stenosis, heart valve replacement and myocardial infarction(ventricular thrombus formation).
Metastasis	Secondary malignant tumor of the heart, arising by lymphatic or haematogenous spread of a primary neoplasm. Presents with dyspnea,congestive heart failure, hypotension and malignante pericardial effusion. The most common primary any primary malignancy may metastasize to the heart, however, lung cancer is among the most common.
