The differential diagnosis of myocardial infarction in patients with a number of potential causes can be challenging, especially when there is no angiographic evidence of coronary obstruction. We describe a case of extensive anterior ST-elevation myocardial infarction in a young male smoker who had a left atrial myxoma and a history of cocaine use 10 hours before the event. Clinical reasoning during a myocardial infarction investigation should be oriented by the probability of the causal relationship between the ischemic event and each factor present in the clinical context...

Myxomas of the nose are very rare benign neoplasms. They grow slowly, infiltrate the surrounding bone cortex, and develop multiple local recurrences with no distant metastasis. Almost, even knowing seen at any age, it is very rare in newborn. The authors present a patient with sinonasal soft tissue fibromyxoma in a newborn baby nose followed by the literature.

A 69-year-old female with left atrial tumor was refered to our hospital for surgical treatment. The tumor was attached to the interatrial septum and resected completely. Histopathological analysis confirmed a myxoma with ossification(mature bone). These findings may support the hypothesis that the undifferentiated mesenchymal cells are the origin of cardiac myxoma.

Cardiac myxomas are frequently located in the left or right atria, with multiple locations being rare. We report a 59-year-old healthy female with 5 months of cough and exertional dyspnea. A transthoracic echocardiography (TTE) exhibits a 9 × 5 cm nonpedunculated tumor arising from the interatrial septum (IAS) and inhabiting both atria, but was unable to depict the relation with the IAS. Transesophageal echocardiography exposes a single tumor crossing the IAS through an ostium secundum atrial septal defect (ASD) causing right heart functional impairment...

Interleukin (IL)-6 is a pleiotropic inflammatory cytokine with both pro- and anti-inflammatory capacities, produced by different cells and tissues, such as leukocytes, adipocytes, and endothelium. From the viewpoint of cardiologists, this cytokine is a reliable biomarker of cardiac dysfunction, occurrence of atrial fibrillation, cardiac myxoma with recurrence, remote metastasis or embolization, and atherosclerotic processes. Although IL-6 levels were detected in patients undergoing cardiac operations and reported sporadically, the perioperative kinetics of IL-6 in cardiac surgical patients was insufficiently elaborated...

Myxomas are the most common benign cardiac tumors and are located more frequently in the left atrium. In the literature there are cases describing the coexistence of thymic tumors and cardiac myxomas. In the case reported herein, during the resection of a cardiac myxoma, an enlarged thymus gland was encountered and resected. The histological exam revealed a thymic hyperplasia. The aim of this case study is to assess the need of conducting further studies in order to identify a common histological pathway between thymic lesions and cardiac myxomas...

INTRODUCTION: Papillary fibroelastoma is one of the most common types of primary cardiac tumour. Though a rare pathology, its importance relates to its form of presentation, with stroke and sudden death, and the questions regarding its management. OBJECTIVES: To review the casuistic of cardiac tumours in our service, in special the papillary fibroelastomas. METHODS: clinical case series overviewing the period from 1st January 2008 to 30th September 2017...

There was no report on the application of totally endoscopic surgery for giant atrial myxoma resection. A 62-year-old female patient with giant atrial myxoma causing severe mitral stenosis and acute pulmonary edema underwent a successful operation by totally endoscopic techniques without the assistance of robotic systems using four small trocar ports (three 5-mm trocars and one 12-mm trocar). The patient recovered uneventfully and was satisfied with cosmetic results.

OBJECTIVE: To integrate the available data published on odontogenic myxoma (OM) into a comprehensive analysis of its clinical/radiologic features. METHODS: Electronic search undertaken in January/2018, looking for publications reporting cases of OM. RESULTS: 377 publications included. We identified 1692 lesions and 695 were used for analysis of recurrence. There is predominance of OMs in females and in mandibles. OMs usually present with bone expansion, asymptomatic cortical perforation, multilocular...

A 14-month-old male presented with paroxysmal nocturnal dyspnea and grade III/VI systolic ejection murmur at the upper left sternal border with an S4 gallop and was subsequently found to have a right ventricular cardiac myxoma. Prior presentations of these tumors have been with exertional syncope and murmur, asymptomatic murmur, or exertional dyspnea; the presentation of such a tumor with paroxysmal nocturnal dyspnea is novel.

BACKGROUND: Odontogenic myxoma (OM) is a benign intraosseous neoplasm that exhibits local aggressiveness and high recurrence rates. Osteoclastogenesis is an important phenomenon in the tumor growth of maxillary neoplasms. RANK (Receptor Activator of Nuclear Factor κappa B) is the signaling receptor of RANK-L (Receptor activator of nuclear factor kappa-Β ligand) that activates the osteoclasts. OPG (osteoprotegerin) is a decoy receptor for RANK-L that inhibits pro-osteoclastogenesis. The RANK / RANKL / OPG system participates in the regulation of osteolytic activity under normal conditions, and its alteration has been associated with greater bone destruction, and also with tumor growth...

Right ventricular (RV) myxomas are extremely rare, but may have dreadful clinical sequelae including pulmonary embolism (PE). We present a case of a patient who had an RV myxoma that was attached to the tricuspid valve, and therefore could not be resected completely during surgery, and remnants of the tumor were seen on transthoracic echocardiogram during post-operative follow-up. Five months after surgery, the patient had PE, which could be due to tumor emboli or thromboemboli. Since repeat surgical resection was not feasible, the patient was started on warfarin...

BACKGROUND: Carney complex (CNC) is a very rare disease. Although thyroid lesions are included in the diagnostic criteria for CNC, they are an infrequent occurrence. CASE PRESENTATION: The patient was a 69-year-old woman who had undergone the removal of a left atrial myxoma 10 years earlier, at the age of 59. At the time of the operation, thyroid ultrasonography (US) revealed multiple hypoechoic nodules. Thyroid scintigraphy revealed an increased uptake of 99m Tc in these lesions, which was consistent with toxic multinodular goiter, and she was diagnosed with CNC...

Cardiac myxomas are the most common type of primary cardiac tumour. The most common location of cardiac myxoma is left atrium. Right atrial myxomas are very rare and usually asymptomatic or sometimes present with dyspnoea. Right atrial myxoma presenting as a right-sided heart failure is very rare. We report a very rare case of a 52-year-old man of right atrial myxoma presented unsually as right-sided heart failure.

Asp-Glu-Ala-Asp (DEAD)-box polypeptide 5 (DDX5), also called p68, is a prototypical member of the large ATP-dependent RNA helicases family and is known to participate in all aspects of RNA metabolism ranging from transcription to translation, RNA decay, and miRNA processing. The roles of DDX5 in cell cycle regulation, tumorigenesis, apoptosis, cancer development, adipogenesis, Wnt-β-catenin signaling, and viral infection have been established. Several RNA viruses have been reported to hijack DDX5 to facilitate various steps of their replication cycles...

Cardiac myxoma is a benign tumor, but it is known for its space-occupying effect at the site of origin and frequent systemic embolization. This case report highlights a biatrial myxoma of interatrial septum who presented with significant tricuspid valve regurgitation, atrial fibrillation, and cardioembolic stroke of the left parietal lobe, i.e., a biatrial myxoma with triple ripples.

Emboli are common clinicopathologic findings. Recognition of the type of arterial emboli could be the first clue to the original source. Emboli with myxomatous changes are rare. Myxoma-like features in mural organizing thrombi have been reported. The most challenging differential diagnosis is between embolic cardiac myxomas and myxomatous thromboemboli. Emboli from sarcomas and arteriosclerotic plaques with myxoid features are also potential pitfalls. There is scarcity of studies focusing on myxoid emboli and their clinical and pathologic importance...
