REVIEW
Chiara Lestuzzi
PURPOSE OF REVIEW: Primary cardiac tumors are a rare disease, which may have severe clinical consequences. Malignant tumors may be misdiagnosed as mixomas, with improper treatment. The aim of this review is to report how to make a differential diagnosis using old and modern tools, the latest trends in tumor classification and treatment, and their possible impact on prognosis. RECENT FINDINGS: Papillary fibroelastomas seem to be more frequent than previously reported, and surgery is also suggested in asymptomatic patients...

Cardiac tumors, are a rare pathology (0.002-0.3%) in all age groups, however, they have a clinic importance, due the affected organ. They are classified in primary (benign or malignant) and secondary (metastasis) types. Among primary type, mixoma, is the most common benign tumor, and sarcoma represents most of the malignant injuries. Cardiac metastasis are more frequent than primary tumors. Clinic effects of cardiac tumors are unspecific and vary according their location, size and agresivity. The use of Multidetector Computed Tomography (MDCT) and Magnetic Resonance Imaging (MRI) assist on the location, sizing, anatomical relationships and the compromise of adyacents structures, besides, MRI is useful for tissue characterization of the tumor...

REVIEW
Omar Hernández-Bringas, Carlos Ortiz-Hidalgo
Mixomas are the most common primary cardiac tumors with an estimate incidence of 0,5-1 per 10(6) individuals per year. These tumors have generated interest due to their unique location (left side of the atrial septum near the fossa ovalis), variable clinical presentation and undefined histogenesis. Most cardiac myxomas occur sporadically while approximately 10% of diagnosed cases develop as part of Carney complex. This neoplasm is of uncertain histogenesis, however, endothelial, neurogenic, fibroblastic, and cardiac and smooth muscle cells differentiation has been proposed, and rarely glandular differentiation has been observed...

Morphological, immunohistochemical and ultrastructural but also clinical and prognostic differences between multiple types of mesenchimal (stromal, nonepithelial) tumors of the gastrointestinal tract prompted us the remembrance of an anecdotic series of sixteen observations of mesenchymal "nonstromal" gastrointestinal tumors (MNSGIT) encountered in four decades of surgical practice. The diagnosis was mainly established on clinical grounds (dyspepsia, pains, digestive hemorrhage or obstruction, palpable tumor) - some lesions being incidentally discovered - and confirmed by radiology, endoscopy, intraoperative exploration and microscopic pathology examination which revealed 9 schwannomas, three leiomyomas, two lipomas, fibroma and "mixoma" one case each...

A 54-year-old woman with history of septal atrial mixoma surgically treated and drug-refractory supraventricular tachyarrhythmia underwent catheter ablation of macro-reentry areas near the pericardial patch placed to repair an interatrial defect. The use of ablative therapy has been successful to cure this arrhythmia.

The aim of this study was to investigate the presence of mast cells in a series of odontogenic tumors. Forty-five cases of odontogenic tumors were investigated using immunohistochemistry for mast cell triptase, and differences between groups were statistically evaluated. Mast cells were present in 96% of odontogenic tumors. Mast cells present in solid ameloblastoma were observed in the tumor stroma surrounding more solid and follicular epithelial islands, with or without squamous metaplasia. The odontogenic mixoma showed few mast cells...

Vaccinia virus (Vv) is a member of the genus Orthopoxvirus, one of seven genera included in the family Poxviridae. Most of these viruses infect vertebrates (Orthopoxvirus, Avipoxvirus, Capripoxvirus, Leporipoxvirus, Suipoxvirus, and Parapoxvirus), but one genus, Entomopoxvirus, infects insects. It is interesting to note that the Fibroma and Mixoma viruses of the leporipoxvirus genus cause tumors in their hosts (rabbits), these being the only tumorigenic viruses in the family (1,2).

EDITORIAL
E I Chazov
Recent research performed in the Cardiology Research Center (CRC) and on-going studies reviewed in the article confirm the hypothesis suggested by CRC investigators about the role of a damaging action of some reactions in the body. The damage to the cell and subcell structures is done by such substances as malonic dialdehyde, methylglyoxal, active oxygen forms (nitric oxide and others). This damage can be used in diagnosis and treatment of cardiovascular diseases. A group of peptides, neuropeptide FF and its receptors in particular, are studied for regulation of the vascular tonicity and perspectives of practical application...

We report a case of an asymptomatic patient in whom a right atrial mass was fortuitously documented by echocardiography few months after a transcatheter radiofrequency catheter ablation for recurrent AF. No masses were seen in the cardiac chambers before the ablative procedure, raising important diagnostic and decision-making issues. The patient was referred to the surgeon and a diagnosis of right atrial myxoma was made.

Lipomatous hypertrophy of the interatrial septum (LHIS) is an increasingly recognized heart condition characterized by fatty deposits in the interatrial septum with sparing of the fossa ovalis. Its distinctive characteristic features by imaging techniques, benign nature, and the fact that most patients remain asymptomatic, has limited the need for histological confirmation and operative intervention in most cases. In this report, we describe two cases of LHIS where cardiac surgical intervention was indispensable: in the first patient, due to the presence of an additional left atrial tumour found out as mixoma and in the second, to relief a superior vena cava obstruction together with bypass grafts for severe coronary artery disease...

INTRODUCTION: Patients benefit, reduction of treatment costs, as well as providing data needed for the science progress, are only some of the items that implicate the importance of preoperative evaluation of operative risk and mortality. In order to determine the risk profile of adult cardiac patients and identify the mortality in different procedures, a set of multicentric clinical studies has been carried out in the past decade. A study involving 19030 patients in 128 centers from 8 European countries was conducted at the end of 1995...

BACKGROUND: Although clonal origin is an essential step in the comprehension of neoplasias, there have been no studies to examine whether odontogenic tumours are derived from a single somatic progenitor cell. The purpose of this study was to investigate the clonal origin of odontogenic tumours. METHODS: Fresh samples of seven ameloblastomas, two odontogenic mixomas, two adenomatoid odontogenic tumour, one calcifying odontogenic cyst, one calcifying epithelial odontogenic tumour (CEOT) and six odontogenic keratocyst (OKC) of female patients were included in this study...

We report the experience in the diagnosis of primary cardiac tumor during the period from 1999 to 2004, 8500 studies were revised echocardiographic carried out. We found 21 patients, 11 of female sex (55%). In 15/21 (71%), the age of presentation was less than 1 year. In 9/21 the tumor was multiple (42.8%), lodged in the ventricle right in 2/21 (9.5%), in the ventricle left 3 (14.2%), 8 in the septum interventricular (38%) and 4 compromised the auriculas. They were classified like rabdomiomas 14 (66%), 5 associates with sclerosis tuberosa, 4 mixomas (19%), 2 fibromas (9...

Peculiarities of malignant cardiac tumors surgical treatment were studied, basing on analysis of 33 observations. Rhabdomyosarcoma was diagnosed in 9 patients, angiosarcoma--in 11, leyomyosarcoma--in 6, malignant mixoma--in 4, fibrosarcoma, chondrosarcoma and liposarcoma--each as a single observation. Special attention was paid to guarantee the maximal radicalism in the tumor excision, what made it necessary in 8 observations to perform additive surgical procedures, such as interatrial septum and atrial walls plasty, plastic operations on cardiac valves and the valves prostheses...

A 68-year-old woman came to our observation with a clinical history of isolated systolic hypertension poorly controlled by the combination of ramipril 5 mg and hydrochlorothiazide 12.5 mg o.d. The ECG showed sinus rhythm with heart rate of 68 beats per minute and signs of left ventricular hypertrophy without strain. Further investigation included an echocardiogram that showed normal left and right cavities and normal cardiac valves. At the level of the posterior wall of the right atrial (RA) an apparent smooth, bean-like tumor, having a thin pedicle, was identified as a RA mixoma...
