1/202. Minimally invasive extirpation of a left-ventricular myxoma.As myxomas usually are benign neoplasms a minimally invasive technique would be an interesting alternative for their extirpation because the surgical trauma is reduced. In one male patient with a diagnosed left-ventricular myxoma minimally invasive surgery was carried out using the Port-Access method. 2D echocardiography, EBT, and MRI were performed preoperatively to obtain exact information about topography, calcifications, and malignity. Minimally invasive extirpation was successful and the mitral valve could be preserved. Histopathological examination revealed a cardiac myxoma extirpated in toto. At one-year follow-up there was no recurrence of the tumor.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/202. Cardiac angiosarcoma: early diagnosis. A case report.Malignant tumours are rare and their diagnostic verification is more frequent at a post-mortem examination. We present a clinical case of a angiosarcoma of the atrium dextrum in a patient where the diagnosis was done precociously. The clinical case we are describing presents some characteristics not noted in literature. The patient did not present any other clinical signs other than giving assumption of the presence of neoplasm and/or secondary localization. The transthoracic echographic exam revealed the methodology to enable the removal of the neoplasm, the outline of which, was better defined with the transesophageal probe.- - - - - - - - - - ranking = 2keywords = neoplasm (Clic here for more details about this article) |
3/202. Cardiac autotransplant for surgical treatment of a malignant neoplasm.Because of their anatomic location, cardiac sarcomas often interfere with cardiac function. Excision is considered to palliate the cardiac defect, but complete excision is often difficult owing to access, particularly in left atrial tumors. Incomplete resection results in tumor recurrence. To achieve complete resection of a large left atrial sarcoma, we used the technique of cardiac explantation, extracorporeal resection of the tumor with cardiac reconstruction, and cardiac autotransplantation.- - - - - - - - - - ranking = 4keywords = neoplasm (Clic here for more details about this article) |
4/202. Primary pericardial synovial sarcoma with detection of the chimeric transcript SYT-SSX.We report a case of a 19-year-old woman with a primary pericardial synovial sarcoma that extended from the right ventricular free wall to the posterior aspect of the left anterior thoracic wall. Synovial sarcoma was diagnosed by the detection of the chimeric transcript SYT-SSX using reverse transcriptase-polymerase chain reaction (RT-PCR). This transcript is generated by reciprocal translocation between chromosomes X and 18, and is specific to synovial sarcoma that usually occurs in the extremities of young adults. When pathological and immunohistochemical diagnosis of synovial sarcoma is difficult, the molecular biological technique using RT-PCR becomes a powerful method of confirmation of this neoplasm.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
5/202. Primary cardiac lymphoma. A case report and review.Primary cardiac lymphoma is classically defined as an extranodal non-Hodgkin's lymphoma exclusively located in the heart and/or pericardium. However, over the last few years, this definition has been extended to include other localizations on condition that these are clearly less important then a cardiac site, that must remain the first, during the illness course, and the most important for its entity. PCL is extremely rare in immunocompetent patients, accounting for 1.3% of all cardiac tumours and 0.5% of all extranodal lymphomas, but it has been encountered with increasing frequency in patients with AIDS or other severe immunodepressive syndromes. PCL is difficult to diagnose, especially during the early stage of the disease, because of its non-specific clinical manifestations, the limited possibility of using non-invasive diagnostic techniques, and difficulties or delays in applying invasive methods. The malignancy of its histotypes and its delicate location are responsible for its rapid and frequently unfavourable evolution. Successful treatment, which is mainly based on anthracycline-containing polychemotherapies, is heavily dependent on an early diagnosis. After a general review of the literature, the authors describe the clinical case of a patient with a PCL that had a secondary central nervous system location, treated with polychemotherapy and autologous peripheral blood stem cell transplantation. Emphasis is placed on the fact that it is more difficult to eradicate the disease from the central nervous system than from the heart.- - - - - - - - - - ranking = 0.026588656961441keywords = central nervous system, nervous system (Clic here for more details about this article) |
6/202. Successful one-stage resection of intravenous leiomyomatosis of the uterus with extension into the heart.Intravenous leiomyomatosis of the uterus is a rare neoplasm characterized by nodular masses of benign smooth muscles with intraluminal growth to the inferior vena cava and, in some cases, to the heart. It may cause abdominal and cardiovascular symptoms and is a serious risk of death when it reaches the tricuspid valve. Surgery is the best treatment and must be applied as soon as possible using cardiopulmonary bypass. The authors report a new case that had cardiac involvement and was successfully resected. The symptoms, imaging diagnosis, pathological and histopathological findings, tumors that mismatched the intravenous leiomyomatosis (IVL), and the use of circulatory arrest and deep hypothermia are discussed. A review of the literature is included.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
7/202. Symptomatic intracavitary (noninvasive) cardiac metastasis from low grade endometrial stromal sarcoma of the uterus.We report a 49-year-old woman who was operated upon 33 years ago for uterine endometrial stromal sarcoma of low-grade malignancy. The patient showed obstruction of the right ventricular outflow tract. An echocardiogram and MRI showed that a mass emanating from the inferior vena cava filled the right atrium, the right ventricle, and part of the pulmonary artery. The entire intracavitary neoplasm was successfully removed and diagnosed as low-grade endometrial stromal sarcoma. To our knowledge, this is the second report of a low-grade endometrial stromal sarcoma reaching the heart via the inferior vena cava. In this case an intracavitary metastasis may be a feature indicating the progression of the endometrial stromal sarcoma. Therefore, this neoplasm should be included in the differential diagnosis of cardiac intracavitary neoplasms. patients affected by this tumor may benefit from early identification and resection of the obstructing neoplasm.- - - - - - - - - - ranking = 4keywords = neoplasm (Clic here for more details about this article) |
8/202. Cardiac myxoma with chondroid features.We report a case of a cardiac myxoma with cartilaginous differentiation. Cardiac myxomas are the most common primary neoplasms of the heart. The cell of origin is thought to be a pluripotential cell called the "myxoma cell," which is capable of differentiating towards various tissues, including endothelial, epithelial, and smooth muscle; however, cartilaginous differentiation is so uncommon that other entities such as metastatic chondrosarcomas must be considered in the differential diagnosis. These entities are discussed along with the radiologic-pathologic correlation.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
9/202. Prenatal detection of cerebral lesions in a fetus with tuberous sclerosis.We report a newborn, diagnosed prenatally with both cardiac rhabdomyomas and a brain tumor. To the best of our knowledge, this is the first report of central nervous system (CNS) lesions detected prenatally in a child with tuberous sclerosis with term follow-up. At 36 months, the child has normal growth and is developing appropriately. Thus the finding of CNS tumors on fetal ultrasound examination can help in the prenatal diagnosis of tuberous sclerosis but does not necessarily indicate a poor prognosis.- - - - - - - - - - ranking = 0.013294328480721keywords = central nervous system, nervous system (Clic here for more details about this article) |
10/202. atrial fibrillation and tumor emboli as manifestations of metastatic leiomyosarcoma to the heart and lung.leiomyosarcoma is a malignant tumor of the smooth muscle that rarely occurs in the gastrointestinal tract. High-grade leiomyosarcomas of the rectosigmoid usually metastasize to the liver and lungs. Although it is unusual, metastases to the heart have been reported. When this occurs, the metastatic tumor usually seeds in the right atrium and pulmonary artery. We report on and discuss a patient who had atrial fibrillation, peripheral emboli, and thrombocytopenia resulting from a low-grade rectosigmoid leiomyosarcoma metastatic to the pulmonary vein and left atrium. atrial fibrillation is not a common manifestation of malignant neoplasms that have spread to the heart. Surgical removal of the tumor terminated the arrhythmia and thrombocytopenia.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
