Although cardiac myxoma is one of the most common types of benign cardiac tumors, infected cardiac myxoma is very infrequent. The diagnosis of infected cardiac myxoma may be challenging because the presenting symptoms are non-specific and established management guidelines are lacking. This report describes a 39-year-old woman with a 5-month history of uncontrolled fever, chills, and myalgia who was diagnosed with myxoma and underwent mass excision. Although blood and urine cultures were negative for growing bacteria, a pathologic examination showed that the excised mass was a left atrial myxoma, with pan-bacterial polymerase chain reaction (PCR) of the surgical specimen revealing Haemophilus parainfluenzae at 99.87%, resulting in a diagnosis of infected cardiac myxoma. Laboratory tests, such as PCR, may supplement culture results in the diagnosis of infected cardiac myxoma.

Systemic emboli occur in approximately one-third of patients with cardiac myxoma. Embolization is common because of the friability of the tumor and intracardiac location. Embolic episodes in young patients with normal sinus rhythm should arouse suspicions of cardiac myxoma in the absence of active endocarditis. We present one case of 17 years old girl having saddle embolism combined with left atrial myxoma. We planned staged operation. First, the emergency thromboembolectomy of aortic bifurcation was performed through bilateral transfemoral approach with use of Forgaty catheter. One week later, the extirpation of myxoma was successfully done with ECC.

Myxoma constitue about 50% of a II primary cardiac, tumor (incidence 0.03%) and occur in any of the cardiac chambers, but about 75% of themare found in the left atrium. As is well known, left atrial myxoma usually simulates mitral valvular disease, and it tends to bring about postural syncope and frequent embolic manifestaticns. The clinical manifestation of left atrial myxoma upon the circulation are obstructive effects, embolic effects and constitutional effects. Diagnosis is now most of all important since surgery can be dramatically curable, whereas untreated myxoma apparently invariably lead to deadful course. Preaprative diagncsis by echocardiogram is so simple and accurate for detection of myxoma that awareness of mitral valvular heart disease with rapid deterioration must be screened. We have diagnosed one case of the left atrial myxoma preopratively by phonocardiogram, echocardiogram and levophase pulmonary angiograJ;n and successfully treated by operation under extra corporeal circulation. A 38 years old housewife was admitted to the National Medical Center because of dyspnea, and paroxysmal cough on occasions for prior to hospitalization. Operation was carried out by median sternotomy and left atriotomy with mild hypothermia under E.C.C. The left atrial myxoma was extirpated including endocardial fragment and its weight was 23gm. The hospital course was not eventful and she can work nowadays without symptoms.

A 33-year-old man presented to the physician with epigastric discomfort. Computed tomography of the chest and echocardiography showed a mass in the left atrium; this mass was resected and diagnosed as myxoma. 12 months later, myxoma recurred in the right atrium, and it was resected without recurrence for 10 months until now. As there are only a few reports on recurred right atrial myxoma after left atrial myxoma, we report here on successful surgical removal of a recurred right atrial myxoma after resection of left atrial myxoma.

A surgical operation on a patient with infected left atrial myxoma is presented. The patient was a 50-year-old woman who was admitted to the Kyung Hee Medical Center Hospital on March 7 1987 with complaints of high fever, cough and dyspnea that occurred a few days prior to admission. She, who no definite history of the previous cardiac-related problems was obtained from, had visited a dentist to have her eight teeth pulled out a few months prior to this admission. A preoperative 2-D echocardiogram revealed a left atrial tumor, strongly suggesting myxoma and two blood cultures drawn prior to surgery yielded streptococcus viridans. Under the preoperative impression of an infected left atrial myxoma, the tumor was removed through a biatrial approach after establishing CPB and cold cardioplegic. Pathologic examination of the tumor demonstrated a typical myxoma with bacterial colonies within. Postoperative course was uneventful and she was completely well at discharge from the hospital. To our best knowledge, this report is the first surgical experience of infected left atrial myxoma in the Korean literature.

The odontogenic myxoma is an infiltrative benign tumor of bone that occurs almost exclusively in the jaw bones and comprises 3% to 6% of odontogenic tumors. This neoplasm is thought to arise from the primitive mesenchymal structures of a developing tooth, including the dental follicle, dental papilla, or periodontal ligament. Radiographically the odontogenic myxoma may produce several patterns: unicystic, multilocular, pericoronal, and radiolucent-radiopaque, making the differential diagnosis difficult. In this report, two cases of the odontogenic myxoma in the jaw bones are presented. The first case involved only the mandible, while the second case involved the maxilla. Both cases presented extensive multilocular radiolucencies characteristic of odontogenic myxoma.

This is a report of a biatrial cardiac myxoma in a young man with a 10-month history of exertional dyspnea and palpitation. The echocardiogram revealed biatrial myxoma prolapsing through the mitral and tricuspid valves during diastole. All cardiac chambers were enlarged and dysfunctional. The electrocardiogram revealed a rapid ventricular response with atrial flutter rhythm. The masses were resected and diagnosed as myxoma by a histological examination. The follow-up echocardiogram revealed significant improvement in ventricular function and reduction in the cardiac chambers' volume. There was no evidence of myxoma recurrence. The most probable cause of the patient's heart failure was considered to be tachycardia-induced cardiomyopathy.

Myxoma is an uncertain mesenchymal cell origin, characterized by irregular round, stellate or spindle cells surrounded by the matrix containing abundant mucoid material and scant vascularity. Their occurrence in descending order of frequency is in the heart, subcutaneous tissue, bone and genitourinary tract. In the head and neck region, the most predilection sites are mandible and maxilla(more than 80%). Laryngeal myxoma is extremely rare：only 5 cases have been reported in the English literature. We report a rare case of laryngeal myxoma. A 60-year-old man with hoarseness visited the out-patient department. The mass was located between the vocal fold and the vocal ligament, filling with the left laryngeal ventricle. We planned the laryngo-microsurgery and successfully excised using $CO_2$ laser. The histopathologic finding revealed the myxoma. After 18 months of surgery, there is no evidence of recurrence and mucosal scarring in the vocal fold. This report is the first case of laryngeal myxoma involving the laryngeal ventricle and the true vocal cord together.

Since Virchow first introduced the term myxoma to describe a tumor that recapitulates the structure of the umbilical cord, it has been increasingly recognized that many diverse neoplasms may acquire a similar myxoid appearance. Myxoma have evolved within the pathology literature from tumors often described in practically all sites to the currently recognized subtypes restricted to the heart, skin, soft tissue, and bone. Pulmonary myxoma is extraordinary rare. We experienced pulmonary myxoma in a 63 year old man. The pulmonary radiology showed mass in right upper lung field, and percutaneous transthoracic needle lung biopsy was performed to confirm the myxoma.

A 76-year-old woman with hypertension was admitted to the hospital with complaints of chest pain and dyspnea. An echocardiogram and pulmonary computed tomography angiography showed right atrial myxoma complicated with pulmonary thromboembolism. An operation to resect the right atrial myxoma and pulmonary embolism was recommended; however, the patient refused and was discharged with anticoagulation therapy. Two years later, she developed dyspnea. Radiological studies and echocardiography showed similar results with the previous findings. The patient underwent mediastinotomy with resection of the right atrial myxoma and pulmonary embolectomy. As there are few reports on right atrial myxoma complicated with pulmonary embolism, we report a successful case of surgical removal of right atrial myxoma and pulmonary embolism.
