AIMS To compare the expression of S100 protein, alpha-smooth muscle actin (alpha-SMA) and keratin 19 in odontogenic myxomas and non-odontogenic myxoid lesions. METHODS Formalin fixed, paraffin wax embedded tissue from seven odontogenic myxomas, three soft tissue myxomas, six hyperplastic myxoid dental follicles, two intramuscular myxomas, 12 cardiac myxomas, and seven normal dental follicles ...

Background Primary cardiac masses are rare and usually benign. Myxomas are usually seen in adults, accounting for 25%-40% of all cardiac tumors from birth to adolescence. The majority of myxomas (75%) are located in the left atrium. Right ventricular myxomas are very rare, only found in 2%-4% of cases. The most important distinguishing feature of a myxoma is the characteristic narrow stalk and ...

Primary cardiac tumors are rare and most frequently benign. The common primary myxomas. Early clinical symptoms can resemble different cardiovascular systemic diseases. heterogeneity in their presentation is due to the localization of myxomas structural characteristics. In cases an echocardiographic examination sufficient establish diagnosis. diagnosis referral for surgery prevent debilitating ...

OBJECTIVE To determine whether atrial myxomas express antigens suggesting a neural origin. DESIGN A retrospective analysis based on immunohistochemical examination of myxoma tissue. SETTING Atrial myxomas excised by two tertiary referral cardiothoracic surgical units. SUBJECTS 24 excised atrial myxomas. Three were from known cases of familial myxoma syndrome. METHODS Immunohistochemical...

Neoangiogenesis is involved in the development and progression of malignant tumors. Vascular endothelial growth factor (VEGF) and its receptors have been designated a central part in this process. Since the significance of the assessment of angiogenesis in soft tissue tumors is still a matter of debate, we investigated the vascularisation of cardiac myxomas and compared it with pulmonary artery...

BACKGROUND Cardiac myxoma is the most common primary cardiac tumor. Approximately 75-80% of myxomas are located in the left atrium. Occurrence of multiple myxomas is extremely rare. CASE PRESENTATION We describe a rare case of biventricular myxomas resulting in right ventricular inflow and tricuspid valve obstruction. The lesions were detected by echocardiography and thoracic computerized tom...

We present a 25 year old Caucasian male patient with multiple recurrences of cardiac myxomas after surgical removal of the original tumor. His mother was operated on for right ventricular myxoma. The genetic analyses disclosed an aneuploid DNA content by flow cytometry analysis. The familial form of the cardiac myxomas must be distinguished from Carney complex syndrome. A long- term echocardiog...

The majority of cardiac tumors are metastatic neoplasms, but primary cardiac tumors are also an important cause of patient morbidity and mortality and occur in 3/1000 of all individuals. About half of primary cardiac tumors and 75% of benign primary cardiac tumors are myxomas. Lipomas, rhabdomyomas, and fibromas make up the majority of the remaining benign tumors. This work describes the clinic...

Cardiac myxomas make up approximately 50% of all benign cardiac tumors and represented 86% of all surgically treated cardiac tumors. Most of them originated from the left atrium, in some cases from both of atria. We report a case of male patient with biatrial myxomas and other extra-cardiac involvement: hypophyseal adenoma, enlargement of thyroid gland, tubular adenoma polyp of colon and bilate...

Myxomas of the jaws are believed to arise from odontogenic ectomesenchyme. They bear a close resemblance to the mesenchymal portion of a developing tooth. Myxomas are predominantly found in young adults. Radiographically myxomas appear as unilocular or multilocular radiolucencies. The radiolucent defect can contain thin, wispy trabeculae of residual bone which are often arranged at right angles...
