Background: Myxoma makes up close to 50% of adult primary cardiac tumors, and this mainly occurs in the left atrium, and rarely in the right atrium or ventricle. The patients clinically present with symptoms of hemodynamic obstruction, embolization or constitutional changes. Diagnosis is currently established most appropriately with 2-D echocardiography. Surgical resection of myxoma is a safe and effective treatment, Material and Method: We reviewed our clinical experience in the diagnosis and management of 57 cases of cardiac myxoma that were seen over a 20-year period from July 1984 to July 2004. Result: The mean age of the patients was $53.5{\pm}14.0$ years (range: 12 to 76 years). There were 38 (67%) females and 19 (33%) males. The preoperative symptoms included dyspnea on exertion in 27 patients, palpitation in 4, chest pain in 9 and syncopal episode in 4. The diagnosis was made by echocardiography alone in 51, and by combination of echocardiography, CT and angiography in 6. The tumor attachment sites were the interatrial septum in 50, the mital valve annulus in 3 and the left atrial wall in cases, The tumor was excised successfully via biatriotomy in 33 (58%), left atriotomy in 15 (26%), the septal approach via right atriotomy in 3, Inverted T incision in 3 and the extended septal approach in 3. The follow-up time ranged from 1 to 229 months (mean follow-up: $84.0{\pm}71.3$ months). There were no early and late deaths and no recurrence during the follow-up period except for follow-up loss in 5 patients. Conclusion: It's concluded that excision of cardiac myxoma is curative and the long-term survival is excellent. Immediate surgical treatment was indicated because of the high risk of embolization or of sudden cardiac death. Radical tumor excision may prevent recurrences.

Intracardiac varix is an endocardial, unilocular, blood-filled cyst that's lined by endothelial cells and it is filled with organizing thrombi. It has been reported that intracardiac varix is an extremely rare entity. We report here on two cases of intracardiac varix in the right atrium and these cases had been preoperatively misdiagnosed as myxoma.

The primary cardiac tumor was considered as a form of disease with poor prognosis in the past and it was hardly diagnosed before post mortem autopsy. But recent development of diagnostic procedure and the cardiac surgery using extracorporeal circulation increased the accuracy of diagnosis and the opportunity of successful treatment. The authors present two cases of left atrial myxoma which experienced during recent 4 years between 1979 and 1982. A 33 year old woman admitted with severe shortness of breath, generalized edema, ascites and the evidence of hepatopathy resulted from right sided heart failure. Preoperatively, the patient was treated with conservative medication to improve general condition for a few days. The tumor mass was removed successfully under the cardiopulmonary bypass. She, however, died of myocardial dysfunction showing low blood pressure. The tumor mass weighed 22gm and measured 5.2x4.5x3.6 cm in size. A 60 year old man admitted with shortness of breath on exertion and an episode of fainting. Following the removal of tumor mass under the cardiovascular bypass, the clinical course was satisfactory with no complication. The tumor mass weighed 105gm and measured 9x4x5 cm in size.

We experienced 6 cases of primary cardiac tumor, all received operation for removal of tumor. Mean age was 43.8 years-old ranging from 17 years-old to 66 years-old. Five cases were female, one case was male. Five cases were benign, myxoma, all located within left atrium. One case was malignant, angiosarcoma within right atrium. All patient showed cardiac manifestations. One case was in NYHA functional class II, two were in III, three were in IV. Four patients showed constitutional symptoms, but no one showed evidence of embolic phenomenon. All case of myxoma showed cardiomegaly except one malignancy. Only one case was regular sinus rhythm, three were sinus tachycardia 8z two were atrial fibrillation. The most common site of tumor origin was fossa ovalis limbus[four of all]. Two of five myxomas received emergency operation, one patient died postoperatively. Lived four patients showed no evidence of recurrence[mean follow-up, 3,5 years], but one patient has Grade II /IV mitral regurgitation & in OPD follow-up now, One malignant case, 17 years-old cerebral palsy female, was angiosarcoma occupied most of right atrial chamber originated from anterior wall of right atrium, received emergency operation which was removal of mass & reconstruction of right atrium with artificial pericardial patch. This patient died on postoperative 36th day due to persistent LCOS[low cardiac output syndrome] with combined sepsis.

Mazabraud syndrome is a rare benign disease that is accompanied by polyostotic fibrous dysplasia and intramuscular myxoma. Malignant transformation of fibrous dysplasia occurs in approximately 1% of cases. To date, only eight cases of malignant transformation, of fibrous dysplasia to osteosarcoma, in Mazabraud syndrome have been reported worldwide. The authors report the first case of osteosarcomatous transformation in a patient with Mazabraud syndrome in the Republic of Korea, focusing on imaging findings.

Primary and metastatic tumors involving the heart are relatively uncommon in dogs. In this study, we provide the echocardiographic diagnosis of intracardiac masses in 2 Yorksire terrier dogs. In the first case, the mass was attached between ascending aorta and pulmonary artery and caused moderate aortic regurgitation and moderate left ventricular dilation. The case was graded into ISACHC II heart failure. The dog was treated with common cardiac medications (i.e. furosemide, enalapril, pimobendan) and oral chemotherapeutic agent (i.e. lomustine). In the second case, the mass was occupied 2/3 of the left atrium and caused marked dilation of left atrium and severe mitral regurgitation (~5 m/s), but not severe congestive heart failure (ISACHC Ib). Although the nature of progression of the mass was likely to cardiac myxoma, the biopsy was not performed due to the owner's refusal. The dog was currently treated with cardiac medications (i.e. ramipril, clopidogrel) and bronchodilator (i.e. aminophylline). Those two dogs are still survived and are currently regularly checked.

Central odontogenic fibroma is a rare odontogenic neoplasm that originates from odontogenic ectomesenchyme. Here, a case of central odontogenic fibroma in a 17-year-old male is reported. Since the present case showed a multilocular radiolucency with partially ill-defined border between the right mandibular condyle and the distal root of the right mandibular third molar, differential diagnosis involved a wide range of pathosis from benign lesions like ameoloblastic fibroma and odontogenic myxoma to more aggressive lesions such as desmoplastic fibroma, juvenile aggressive fibromatosis, or fibrosarcoma.

Primary cardiac tumors are rare, being found in approximately 1 in 10, 000 routine autopsies in patients of all ages. of the primary cardiac tumors, 75% to 80% of patients are benign lesion, of the benign cardiac tumors, myxoma is the most common type in adults, whereas rhabdomyoma predominates in infants and children. About 50% of cardiac rhabdomyoma patients, die in the first 6 months of life and 80% by 1 year of age. We report on the one infant and the one neonate operated upon successfully for removal of cardiac rhabdomyoma.

Between March, 1988 and July, 1992, 114 patients underwent Open Heart Surgery under hypothermic cardiopulmonary bypass. There were 29 cases of congenital heart anomalies (25％), and 85 cases of acquired heart diseases (75％) consisting of 53 cases of valvular heart disease, 31 cases of ischemic heart disease, and a case of left atrial myxoma. The age distribution of 114 cases was 4 to 73 years, and mean age was 43 years old consisting of mean age of congenital heart disease 23, valvular heart disease 47, and ischemic heart disease 57 years old. Overall operative mortality was about 7.9％.
