1/96. Giant cervico-mediastinal lipoma. A clinical case.The lipoma is a circumscribed mesenchymal tumour originating from adipose tissue. The lesion is usually small and asymptomatic, and is most frequently located in the neck region. The case of a 77-year-old woman with chronic extrasystolic arrhythmia caused by a non-specified ischemic cardiopathy is reported. The woman presented a swelling at the front of her neck, observed for the first time about 6 months previously. This swelling progressively increased in size, provoking dysphagia, dysphonia, persistent cough, dyspnea, light jugular turgor and palpitations. Chest x-rays showed and opaque area at the front of the neck, which extended beyond the jugular incisure by about 2 cm. NMR of the neck showed a gross lipomatous formation at the front, mainly of the left, continuing in the front mediastinal region; the trachea was dislocated to the right and compressed at the back; the vasculo-nervous fasciculus, especially on the left, was compressed and enveloped by the adipose formation. The Holter test confirmed the presence of ventricular and supra-ventricular extrasystoles. Surgery was carried out under local anaesthesia because the displacement of the laryngo-tracheal axes precluded intubation. Histological analysis of the 9 x 4 x 2.2 cm mass confirmed the diagnosis of lipoma. After removal of the mass all the symptoms, which had been provoked by compression, as well as the cardiac arrhythmias disappeared. The prompt disappearance of the latter was particularly surprising. The possibility of the external compression of the nervous structures of the neck should be taken into consideration in cases of ventricular arrhythmia of unknown origin, and systematic study of the region carried out.- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
2/96. Neural compressive symptoms appearing during steroid treatment in a patient with intracranial lipoma.Intracranial lipoma is a rare condition, and it is usually asymptomatic. We describe a 67 year old woman who developed blurred vision, diplopia, left sided oculomotor palsy, and ipsilateral ptosis during steroid treatment for giant cell arteritis. These symptoms were considered to be associated with aggressive giant cell arteritis, and the steroid dose was raised. Surprisingly, the symptoms increased, and further examination revealed an intracranial lipoma situated in the Meckel's cave. During tapering of the steroids her symptoms gradually improved. This is the first report demonstrating that steroids may induce hypertrophy of the fat tissue in the intracranial lipoma, causing compression of the cranial nerves passing through the cavernous sinus thereby mimicking the ocular symptoms sometimes associated with aggressive giant cell arteritis.- - - - - - - - - - ranking = 68.099194906429keywords = hypertrophy (Clic here for more details about this article) |
3/96. Squamous cell carcinoma and lipomatous pseudohypertrophy of the pancreas.A 68-year-old woman who had been treated for non-insulin-dependent diabetes mellitus for the past 20 years was admitted to hospital because of abdominal pain and weight loss. Radiological investigation revealed a tumour in the body of the pancreas and numerous intraductal calcifications in both the tail and the head of the pancreas. Left-sided pancreatectomy was performed to remove the tumour. The resection specimen showed fatty enlargement of the parenchyma and numerous intraductal calcifications in the tissue adjacent to the tumour, which was 7 cm in diameter and was found to be a primary squamous cell carcinoma with a spindle cell component. There was also lipomatous pseudohypertrophy.- - - - - - - - - - ranking = 340.49597453214keywords = hypertrophy (Clic here for more details about this article) |
4/96. Segmental costovertebral malformations: association with neural tube defects. Report of 3 cases and review of the literature.patients with spondylocostal dysostosis (SCD) have vertebral abnormalities and numerical or structural rib anomalies that produce thoracic asymmetry. Rib anomalies and dysmorphism are the typical features that differentiate this syndrome from spondylothoracic dysostosis (STD). Jarcho-Levin syndrome is a severe form with involvement of the whole vertebral column. Other associated findings such as congenital heart defects, abdominal wall malformations, genitourinary malformations and upper limb anomalies may be found; in addition, neural tube defects (NTDs) have been associated with this malformation. SCD is transmitted both in a recessive form and as a dominant defect. We report on 3 children with SCD; 2 also had NTDs. All of them were studied with x-rays and spinal magnetic resonance (MR), and over the same period they underwent multidisciplinary clinical functional evaluation. One of our cases with NTD also presented polythelia, which has not previously been described in patients with SCD. The common association of segmental costovertebral malformations with NTDs could be related to an early gastrulation genomic defect, or one after gastrulation, when there are two independent somitic columns. The latter sometimes progresses and then involves primary and secondary neurulation. Also, the association of SCD with NTDs could be related to the interaction of different genes, resulting in this complex phenotype. Therefore, additional genetical and embryological studies are necessary to provide evidence of an etiological link between SCD and NTD.- - - - - - - - - - ranking = 0.2948384206794keywords = heart (Clic here for more details about this article) |
5/96. Surgical management of extensive lipomatous hypertrophy of the right atrium.Lipomatous hypertrophy of the right atrium is a rare lesion that is usually limited to the interatrial septum. The authors report on a patient that suffered from an extensive lipomatous hypertrophy, which protruded into the right and left atrium as well as the superior vena cava and caused inflow obstruction. Therapeutic management is discussed.- - - - - - - - - - ranking = 408.59516943857keywords = hypertrophy (Clic here for more details about this article) |
6/96. A large false aneurysm of the right ventricle within a giant epicardial lipoma.Lipomas, which account for approximately 10% of all neoplasms of the heart, may be detected in asymptomatic patients by chance during echocardiography, CT scan, or MRI scan. Occasionally, lipomas are complicated by arrhythmias. We describe a patient who presented with severe cardiomegaly and paroxysmal supraventricular tachycardia. An MRI scan showed a large intrapericardial lipoma with two large cavities inside communicating with each other and with the right ventricular chamber through a defect of the right ventricular wall. The mass was partially removed, and the right ventricle was patched. Surgery combined with antiarrhythmic therapy resulted in a good short-term result.- - - - - - - - - - ranking = 48.148300079956keywords = cardiomegaly, heart (Clic here for more details about this article) |
7/96. Polypoid (pedunculated) subepicardial lipoma: a cardiac lesion resembling the epiploic appendage.This report describes a 75-year-old woman with an asymptomatic pedunculated lipoma involving the epicardium of the right atrium. The lipoma was an incidental finding at autopsy. The twisted lesion showed many similarities with the infarcted epiploic appendages observed in the visceral peritoneum.- - - - - - - - - - ranking = 4keywords = cardiac (Clic here for more details about this article) |
8/96. Surgical approach to a giant fibrolipoma of the supraglottic larynx.This paper describes the surgical procedures for a fibrolipoma that first appeared as a giant tumour in the hypopharynx and extended to the cardiac antrum of the oesophagus. At the initial surgery, a pedunculated tumour originating from the left arytenoid of the larynx was found to occupy the cervical as well as thoracic oesophagus and was thus removed through a lateral pharyngectomy. A histological examination revealed fibrolipoma. However there was a recurrence of the tumour in the arytenoid and the patient suffered from dysponea. In addition, a submucosal tumour was also found in the left false vocal fold. At the second surgery, the masses in the arytenoid and false vocal fold were subtotally removed without damaging the mucosa. The mucosa of the arytenoid was sutured to the thyropharyngeal muscle on the same side and the arytenoid swelling disappeared almost completely. The post-operative course has been uneventful for more than two years.- - - - - - - - - - ranking = 1keywords = cardiac (Clic here for more details about this article) |
9/96. A t(2;19)(p13;p13.2) in a giant invasive cardiac lipoma from a patient with multiple lipomatosis.Cardiac lipomas occur infrequently but account for a significant portion of rare cardiac tumors. Common cutaneous lipomas have previously been associated with rearrangements of chromosome band 12q15, which often disrupt the high-mobility-group protein gene HMGIC. In this report, we describe the cytogenetic analysis of an unusual giant cardiac lipoma that exhibited myocardial invasion in a patient with a history of multiple lipomatosis (cutaneous lipoma, lipomatous gynecomastia, lipomatous hypertrophy of the interatrial septum, and dyslipidemia). Cytogenetic studies of cells derived from the cardiac lipoma demonstrated no abnormalities of chromosome 12, but did reveal a t(2;19)(p13;p13.2). A liposarcoma-derived oncogene (p115-RhoGEF) previously mapped to chromosome 19 and the low-density lipoprotein receptor gene (LDLR) previously mapped to chromosome band 19p13 were evaluated to determine whether they were disrupted by this translocation. fluorescence in situ hybridization analyses assigned p115-RhoGEF to chromosome 19 in bands q13.2-q13.3 and mapped the LDLR to chromosome arm 19p in segment 13.2, but centromeric to the t(2;19) breakpoint. Thus, these genes are unlikely to be involved in the t(2;19)(p13;p13.2). Further studies of the regions of chromosomes 2 and 19 perturbed by the translocation in this unusual infiltrating cardiac lipoma will identify gene(s) that participate in adipocyte growth and differentiation and may provide insight into syndromes of multiple lipomatosis.- - - - - - - - - - ranking = 76.099194906429keywords = hypertrophy, cardiac (Clic here for more details about this article) |
