Myxomas are the most common form of intracardiac tumors and are found primarily in the left atrium. In rare cases, Carney and associates have described a syndrome called "the complex of myxoma" consisting of cardiac myxoma, which characteristically is familial, in assocation with two or more of the follow conditions: myxomatous masses (cardiac myxoma, cutaneous myxosma, and mammary myxoid fibroademoma), spotty pigmented lesions of the skin, and endocrine disorders. We report a case of familial atrial myxoma with Carney's complex in a 19-year old woman who has spotty pigmentations on her face, and left atrial myxomas, and myxoma on the right nipple. Her mother and sister share the left atrial myxoma. The myxomas originated in the septum of the left atrium and the anterior leaflet of the mitral valve were successfully excised. In conclusion, family members of affected patients should be screened periodically with echocardiography in an attempt to identify asymptomatic cardiac myxomas. Complete excision and postoperative follow up are necessary to rule out the muticentricity and high rate of recurrent lesions.

Ten percent of all myxomas are the familial form. Familial myxomas appear to have autosomal dominant transmission. We experienced two siblings with familial myxomas. A left atrial myxoma was surgically removed in a 21-year-old woman. Six years later, other myxomas were found in the right atrium and the left atrium and these were also surgically removed. Right ventricular and right atrial myxomas were surgically excised in her brother. The two siblings were found to have frame-shift mutations in the PRKAR1A gene (c.537delA; p.Gly180GlufsX26), which is the causative gene for Carney complex. Obtaining the genetic diagnosis makes it possible to prepare more effective therapeutic strategies for these patients and the gene carriers. Complete excision, ruling out multicentricity and proper postoperative follow up are all necessary to avoid recurrence of myxoma.

Biatrial myxomas are extremely rare, and only two cases have been reported in Korea so far. We report a 60-year-old male patient with decreased mentality due to embolization from myxoma. In this case, two pedicles grew into both atrial chamber separately from the different origins at the atrial septum. The patient underwent emergency operation immediately after the diagnosis by an echocardiography.

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.

Eighteen patients (13 female and ave male) aged from 15 to 62 years (mean age 42.6 years) underwent excision of cardiac myxoma(17 left atrial, one right atrial) between 1985 and 1994 at Pusan National University hospital. All patients complained of exertional dyspnea and most had a few additional symtoms including palpitation, chest pain, syncope, general weakness, weight loss, fever, cough and epigastric disconyort. The diagnosis was made by echocardiography alone in left atrial myxomas but a myxoma in right atrium was diagnosed incidentally during mitral valve replacement for rheumatic valvular heart disease. The tumor attachment sites were fossa ovalis in 13, other interatrial septum in 4, mitral valve annulus in one and free wall of left atrium in two cases. The tumor was excised successfully via right atriotomy in 8 and biatriotomy in 10 cases. There was no hospital nor late death, and no recurrent case during the follow up period. Curative surgical excision of cardiac myxoma can be performed with low morbidity and very low r currence rate.

Mucocele is clinical term used to describe swelling caused by the pooling of saliva at the site of a severed or obstructed minor salivary gland duct. Mucoceles are categorized into two subgroups, extravasation type and retention cyst type. The etiology of extravasation type mucocele is related to mechanical trauma to the minor salivary gland excretory duct, resulting in extravasation of mucus into the fibrous connective tissue so that a cyst-like cavity is produced, but the epithelial lining is absent. Retention cyst type mucocele results from obstruction of minor salivary gland excretory duct, and cystic cavity is lined by epithelial cells. This case report presents a mucocele occurred on the lower lip, and caused by suture silk unremoved for 3 years. Suture silk penetrated and tore the minor salivary gland duct on the lower lip with subsequent extravasation of mucus into the fibrous connective tissue.

Cardiac myxoma is the most common primary tumor of the heart, but right ventricular myxoma causing outflow obstruction is relatively rare. A 15 years old girl developed dyspnea on exertion and intermittent syncope caused by a right ventricular mass obstructing the right ventricle outflow tract. Transthoracic echocardiography revealed $3.6{\times}3.0\;cm$ sized pedunculated subpumonic mass originating from the right ventricular anterior free wall. The patient underwent an emergency operation, consisting of the removal of the mass by wide excision of the tumor base and PTFE (polytetrafluoroethylene) patching of the right ventricular anterior free wall defect. Pathological findings of the mass were compatible with myxoma, and the patient was discharged uneventfully 7 days after the operation.

Oral mucocele is a common exophytic lesion resulting from the accumulation of saliva due to pathological changes in the minor salivary glands. It is typically asymptomatic and painless and characterized by semipermeable, fluctuant nodules. General treatment methods for mucocele include surgical excision, marsupialization, cryosurgery, and steroid injection. This case report presents the treatment of oral mucocele using micro-marsupialization and a tying method as minimally invasive techniques rather than surgical treatment. Based on this case report, it is suggested that micro-marsupialization and the tying method can be used as alternative methods for the treatment of oral mucocele infants and children with behavioral control problems.

Myxoma is the most common primary tumor of the heart. The common symptoms of myxoma can be similar to those of infective endocarditis, which include fever, weight loss, fatigue and arthralgia, but it is very rare for a myxoma to become infected. We report on a case of a 76-year-old male patient with fever and loss of conscious-ness, and he underwent an emergency operation after suffering shock state due to the infected myxoma.

Obstructive intracardiac lesions, like mitral stenosis or insufficiency (MR), by myxomas of the left atrium have been commonly reported, but the attenuation of MR by myxoma combined with coronary artery disease is very rare. We report a 70-year-old female patient whose left atrial myxoma had attenuated moderate MR to mild MR and required mitral valve surgery after removal of the myxoma. She also had coronary artery disease, severe pulmonary hypertension and moderate tricuspid regurgitation due to the mitral valve lesions obstructed by myxoma. The patient underwent removal of myxoma, mitral and tricuspid valve reconstructions, and coronary artery bypass grafting. She was discharged at the postoperative 14 day without any problems.
