Although cardiac myxomas are histologically benign, they may be lethal because of their strategic position. They can mimic not only every cardiac disease but also infective, immunologic, and malignant processes. Myxomas must therefore be included in the differential diagnosis of valvular heart disease, cardiac insufficiency, cardiomegaly, bacterial endocarditis, disturbances of ventricular and supraventricular rhythm, syncope, and systemic or pulmonary embolism. The symptoms depend on the size, mobility, and location of the tumor. Echocardiography, including the transesophageal approach, is the most important means of diagnosis; CT and MRI may also be helpful. Coronary arteriography in patients over 40 years of age is generally required to rule out concomitant coronary artery disease. Surgical removal of the tumor should be performed as soon as possible; the long-term prognosis is excellent, and recurrences are rare. In follow-up examinations as well, echocardiography is essential.

“…Right atrial myxomas may mimic constrictive pericarditis by producing functional stenosis of the tricuspid valve, with increased right atrial pressure [35,36,39]. Ventricular myxomas may mimic stenosis of the aortic or pulmonic valve because of the narrowing of the left or right ventricular outflow tract, respectively and may also cause syncope; embolism is common [31,40,41].…”

Primary cardiac neoplasms are very rare as compared to metastatic tumors. Myxomas are the most common of the primary cardiac tumors. Myxomas represent almost 50% of cardiac masses with an incidence reported at one in 10000 autopsies. A greater percentage (75%) are located in the left atrium, of these, 90% originate from an area in the atrial septum near the fossa ovalis. Right atrial myxoma are un common beign three to four time less frequent that those located in the left atrium. The incidence of those arising in the left and right ventricles is 2.5-4%. We report on case of right ventricular cardiac myxoma, confirmation with histopathological examination, what is first case in forensic medicine practice.

“…While only a subset of CM has macroscopically visible areas of hemorrhage, dispersed microscopic foci of recent and organizing hemorrhage is almost universal feature of all surgically resected tumors, also found in more than a half of the specimens obtained at autopsy. 41 Hemosiderin deposits and Gamna-Gandy bodies are also microscopic remnants of old episodes of hemorrhage [1 and 2].…”
