ABSTRACT

Resumo Neoplasias cardíacas são raras, tendo como principal representante o mixoma atrial (MA), que corresponde a cerca de metade de todos os casos. O MA tem incidência estimada entre 0.001% e 0.3% na população em geral, no entanto apenas aproximadamente 0,06% desses cursam com eventos embólicos coronarianos. Homem de 33 anos, tabagista, admitido com quadro de precordialgia intensa e irradiação para membro superior esquerdo com duração de uma hora. O eletrocardiograma evidenciou elevação de segmento ST nas derivações D2, D3 e aVF troponina sérica elevada, confirmando infarto com supra desnivelamento do segmento ST (IAMCSST). Foi realizada cineangiocoronariografia, a qual revelou oclusão em terço proximal de artéria coronária direita por trombo. Realizada tentativa de aspiração do trombo, sem sucesso, seguido por angioplastia primária com balão sem colocação de stent. Durante a investigação do quadro, paciente realizou ecocardiograma transtorácico o qual demonstrou massa homogênea de superfície regular, de 5.2 cm x 2.3 cm, aderida ao septo interatrial, com lobulações de características emboligênicas prolapsando para valva mitral e ventrículo esquerdo na diástole, compatível com MA. Foi realizada ressecção cirúrgica com paciente evoluindo assintomático, recebendo alta para seguimento ambulatorial. O caso relatado difere em idade e sexo do perfil epidemiológico típico sendo um dos poucos descritos com acometimento da parede inferior apresentando a artéria coronária direita como culpada. Este relato ratifica a importância do diagnóstico diferencial frente às apresentações de IAMCSST em jovens.


Abstract Cardiac tumors are rare entities, among which atrial myxoma (AM) stands as the most frequent, accounting for approximately half of all reported cases. The incidence of AM is estimated to range from 0.001% to 0.3% within the general population, yet only about 0.06% of these cases present with coronary embolic events. We report on a 33-year-old male smoker who experienced acute, severe precordial pain radiating to the left upper limb, lasting for one hour. The electrocardiographic evaluation demonstrated ST-segment elevation in leads D2, D3, and aVF, alongside significantly elevated serum troponin levels, confirming a diagnosis of ST-segment elevation myocardial infarction (STEMI). Subsequent coronary angiography revealed proximal occlusion of the right coronary artery due to thrombus. An initial attempt of thrombus aspiration was unsuccessful, followed by primary angioplasty with balloon inflation without stent placement. Further diagnostic exploration through transthoracic echocardiography identified a homogenous, smooth-surfaced mass measuring 5.2 cm x 2.3 cm attached to the interatrial septum. This mass, characterized by lobulations, prolapsed into the mitral valve and left ventricle during diastole, consistent with AM. Surgical resection of the mass was successfully performed, with the patient being discharged asymptomatic. In the reported case, the patient's profile, notably his age, and gender, diverges from the typical epidemiological characteristics associated with AM. This case adds to the limited number of reports where the inferior wall is affected by the right coronary artery being occluded. This report emphasizes the significance of differential diagnoses in younger patients presenting with STEMI.

ABSTRACT

ABSTRACT Introduction: Primary cardiac myxomas are rare tumors. Concurrent valvular lesion is a common finding on evaluation which is thought to be due to annular dilatation secondary to tumor movement across the valve, functional obstruction across the valve, and severe pulmonary hypertension secondary to chronic obstruction. A common belief among surgeons is that excision of myxoma leads to abatement of symptoms, and further valve intervention may not be warranted. Methods: A 10-year retrospective descriptive study was designed to analyze patients who underwent excision of cardiac myxoma at our center. Data was analyzed regarding presenting features, echocardiographic findings of myxoma and valve morphology, intraoperative assessment, and postoperative outcome with/without valve repair/replacement in all patients. Results: A total of 22 patients underwent surgery for myxoma. Six patients underwent successful mitral valve repair with ring annuloplasty, two had moderate mitral regurgitation, three had severe mitral regurgitation, and one patient had no mitral regurgitation on preoperative assessment, but moderate mitral regurgitation was found intraoperatively. Four of these patients had no residual mitral regurgitation in follow-up period while two had mild residual mitral regurgitation. One patient had severe mitral stenosis of concurrent rheumatic etiology and successfully underwent mitral valve replacement. Conclusion: Cardiac myxomas are rare benign tumors commonly associated with mitral valve insufficiency. Mitral valve should be assessed intraoperatively after excision of mass as preoperative assessment might often be insufficient. Concomitant mitral valve intervention might be needed with a case-specific tailored approach, and mitral valve repair with ring annuloplasty offers best surgical outcome in such cases.

ABSTRACT

El mixoma cardiaco constituye uno de los tumores benignos más frecuentes entre los tumores cardiacos. El mismo se caracteriza por la obstrucción del flujo sanguíneo por trombosis o émbolo, resultando en causa de insuficiencia cardiaca con disfunción ventricular, síncope ortostático, isquemia de diferentes órganos de acuerdo a la arteria afectada, e incluso muerte súbita. Presentamos 2 casos en pacientes pediátricos: el primer caso, una adolescente con ACV isquémico y el segundo caso se trata de un adolescente con isquemia a nivel de miembros inferiores por una tromboembolia en la Aorta distal. En ambos casos se realizó la exéresis del tumor, con éxito.


Cardiac myxoma is one of the most frequent benign tumors among cardiac tumors. It is characterized by the obstruction of blood flow due to thrombosis or embolus, resulting in heart failure with ventricular dysfunction, orthostatic syncope, ischemia of different organs depending on the affected artery, and even sudden death. We present 2 cases in pediatric patients: the first case, an adolescent with ischemic stroke and the second case is an adolescent with ischemia in the lower limbs due to a thromboembolism in the distal aorta. In both cases, the exeresis of the tumor was performed successfully.

ABSTRACT

La enfermedad cerebrovascular constituye una de las principales causas de muerte a nivel mundial. Múltiples factores desencadenan los accidentes vasculares encefálicos isquémicos, entre ellas los tumores cardiacos, como el mixoma auricular. Se presenta el caso de una paciente femenina de 32 años, que al examen físico mostró afasia motora, hemiplejia fascio-braquio-crural derecha y discreta paresia de la mirada vertical con nistagmos. Se realizaron estudios de imagen (tomografía de cráneo, ecocardiograma transtorácico y angiotomografía de vasos de cuello) sugerentes de embolización sistémica en el territorio de la carótida izquierda, secundarios a la fragmentación de un tumor cardiaco. Se decide derivar a la paciente a cirugía cardiovascular para endarectomía carotídea con exéresis del tumor cardiaco, el cual evolucionó satisfactoriamente. Persistió el daño neurológico debido al tiempo transcurrido entre el diagnóstico y el tratamiento. Teniendo en cuenta la baja frecuencia del mixoma cardiaco y la posibilidad de asociarse con ictus isquémico se decide presentar este caso.


Cerebrovascular disease is one of the main causes of death worldwide. Multiple factors trigger ischemic strokes, including cardiac tumors such as atrial myxoma. A 32-years-old female patient, who on physical examination showed motor aphasia, right fascio-brachio-crural hemiplegia and discrete vertical gaze paresis with nystagmus is presented. Imaging studies were performed (skull tomography, transthoracic echocardiogram and angiotomography of neck vessels) suggestive of systemic embolization in the left carotid territory, secondary to the fragmentation of a cardiac tumor. It was decided to refer the patient to cardiovascular surgery for carotid endarectomy with excision of the cardiac tumor, which progressed satisfactorily. Neurological damage persisted due to the time elapsed between diagnosis and treatment. Taking into account the low frequency of cardiac myxoma and the possibility of being associated with ischemic stroke, it was decided to present this case.

ABSTRACT

Introduction: Benign intracardiac tumours are the most common of the 5% of primary tumours and account for 90% of intracardiac tumours. Myxoma, which is the main benign tumour, rarely localizes to the mitral valve, in the order of 1-5%, associated with severe symptoms and enormous complications. The objective is to report a rare and severe case of mitral valve myxoma resulting in severe obstruction of the valve orifice. Presentation of Case: A 65-year-old Moroccan woman, without profession, the diabetic patient presented with progressive dyspnoea, in whom transthoracic echocardiography (TTE) completed by transesophageal echocardiography (TEE), a cardiac magnetic resonance imaging (MRI), a cerebro-throracoabdominopelvic Positron emission tomography-scan (PET-scan) showed a cauliflower-shaped mass embedded in the small mitral valve, evoking the diagnosis of myxoma, confirmed by the anatomopathological examination. A lumpectomy with mitral valve plasty was performed in association with coronary artery bypass surgery for a tri truncal lesion. The evolution was marked by an improvement in the clinical and echographic state. Discussion: Myxoma is the first benign tumour encountered in women between the 3rd and 6th decade, whose diagnosis is evoked by a TTE, better by a TEE or more, by a computed tomography (CT scan) or even a cardiac MRI which specifies the visualization of the soft parts with all the internal details of the myxoma, whose confirmation is carried out on the histopathological analysis of the operating room. Conclusion: The management was based on complete resection of the tumor associated with mitral valve plasty.

ABSTRACT

Myxomas are benign and locally invasive neoplasms of primitive mesenchymal origin. They are most commonly found in the atria of the heart. They have also been reported in bones, muscles, and other connective tissues. Myxomas are rarely found in the nose and paranasal sinuses. Myxomas are notorious for their recurrence after excision and local invasion. We report a case of intranasal myxoma in a 30-year-old male who presented with blocked ear sensation and progressive nasal block. With this report, we intend to increase awareness about the clinical presentation, histologic characteristics, and management options of myxoma

ABSTRACT

Abstract A 33-year-old woman with a history of high blood pressure since she was 8 years old, hypothyroidism, polycystic ovary syndrome, metabolic syndrome, multiple nevi, and a maternal family history of death at age 50 due to malignant high blood pressure and heart failure. Cushing's syndrome secondary to a secretory pituitary microadenoma was diagnosed, being the cause of secondary arterial hypertension, and ruling out other causes such as renal stenosis and coarctation of the aorta. A transthoracic and transesophageal echocardiogram was performed, which detected a left atrial myxoma. Given the presence of an atrial myxoma, Cushing's syndro me and polycystic ovary syndrome, a diagnosis of Carney Complex was made due to the presence of positive Stratakis criteria. The cardiac tumor was resected, and pathology confirmed that it was an atrial myxoma. She evolved clinically stable in outpatient controls in a 6-month follow-up. Resection of the pituitary microadenoma is planned as a curative treatment for Cushing's syndrome and arterial hypertension.


Resumen Mujer de 33 años, con antecedentes de hipertensión arterial desde los 8 años, hipotiroidismo, síndrome de ovario poliquístico, síndrome metabólico, nevos múltiples y antecedente familiar materno de muerte a los 50 años por hipertensión arterial maligna e insuficiencia cardiaca. Se diagnosticó síndrome de Cushing secundario a un mi croadenoma hipofisario secretor, siendo la causa de la hipertensión arterial secundaria, y descartándose otras causas como estenosis renal y coartación de aorta. Se realizó u n ecocardiograma transtorácico y transesofágico que detectaron un mixoma auricular izquierdo. Ante la presencia de un mixoma auricular, síndrome de Cushing y síndrome de ovario poliquístico se llegó al diagnóstico de Complejo de Carney por la presencia de criterios de Stratakis positivos. Se realizó la resección del tumor cardiaco, y la anatomía patológica confirmó que se trataba de un mixoma auricular. Evolucionó clínicamente estable en controles ambulatorios en un seguimiento de 6 meses, y se planifica la resección del microadenoma hipofisario como tratamiento curativo del síndrome de Cushing y la hipertensión arterial.

ABSTRACT

Odontogenic myxoma is a maxillofacial tumor that is benign in nature. It is characterized by a slow-growing, painless, and site-aggressive behavior. A main feature is that it is not encapsulated so it has high potential of invasiveness and penetration into peripheral tissues. Large lesions may cause extensive compromise of the region. Treatment strategy for Odontogenic Myxoma is still controversial. Radical resection with an appropriate surgical margin is recommended, but emerging evidence has suggested that a more conservative approach will result in less morbidity and adequate results. This report shows a remarkable result on a 16-year-old patient who had a Mandibular Odontogenic Myxoma treated with a conservative approach. Intra-lesional absolute alcohol irrigation was performed during a 5-month period. Considerable volume reduction of the lesion happened which allowed a minimal overall resection. No recurrence was found after a 3 year follow-up.

ABSTRACT

Background:Myxomas are the most common primary cardiac tumors that develop mostly at the atrial chambers of the heart and represent 0,25% of all cardiac diseases. Methods: This is a retrospective study aiming to analyze epidemiological and intraoperative data from cardiac myxoma cases in the hospital of the last 32 years. The study population was 145 cardiac surgical patients and was divided into 4 certain 8?year periods. 87,6% of cases had the myxoma located at left atrium and 97,2% of all patients fully recovered. 4,1% of patients relapsed and underwent a redo operation. Results: Mean CPB time and mean ICU length of stay increased during the 8?year periods (p < 0,001, P < 0,001, P = 0,002 and P = 0,003 respectively). In-hospital length of stay decreased to 5 days in the most recent period (p < 0,001). Cases significantly increased to 54 in the last 8?year period (p = 0,009). Conclusion: Improvement on cardiac imaging and a better accessibility may drive patients to earlier and safer diagnosis of myxomas preventing any deterioration of their condition. Improvement on postoperative care can also reduce in-hospital length of stay. Surgical excision is the treatment of choice and guaranteed survival at 97,2% of patients.

ABSTRACT

Resumen ANTECEDENTES: El angiomixoma agresivo profundo perineal es un tumor mesenquimatoso de muy limitada aparición que se origina debido a un crecimiento tumoral del tejido conjuntivo que se expande a pesar de su naturaleza benigna; se caracteriza por un comportamiento agresivo. CASO CLÍNICO: Paciente de 38 años, con un nódulo genital de 3 cm en el labio mayor izquierdo, con sospecha clínica de quiste de la glándula de Bartolino. Durante la intervención para su drenaje se objetivó una tumoración blanda, de aspecto mesenquimal, pediculado. El análisis histológico confirmó que se trataba de un angiomixoma agresivo profundo perineal. Posterior al estudio de extensión negativo, se completó la vulvectomía simple izquierda, con un posoperatorio favorable. CONCLUSIONES: La obtención de una biopsia inicial es decisiva, sobre todo en casos de tumores mesenquimales agresivos, como el angiomixoma agresivo perineal profundo. De esta manera puede establecerse un plan de tratamiento individual en función del diagnóstico histológico definitivo.


Abstract BACKGROUND: Aggressive deep perineal angiomyxoma is a mesenchymal tumor of very limited occurrence that originates due to a tumorous growth of connective tissue that expands despite its benign nature; it is characterized by an aggressive behavior. CLINICAL CASE: 38-year-old patient with a 3 cm genital nodule on the left labium majus, with clinical suspicion of Bartholin's gland cyst. During the intervention for its drainage, a soft, mesenchymal, pedunculated tumor was observed. Histological analysis confirmed that it was an aggressive deep perineal angiomyxoma. Following a negative extension study, a simple left vulvectomy was completed, with a favorable postoperative course. CONCLUSIONS: Obtaining an initial biopsy is critical, especially in cases of aggressive mesenchymal tumors, such as deep perineal aggressive angiomyxoma. In this way an individual treatment plan can be established based on the definitive histologic diagnosis.

ABSTRACT

Introducción: el mixoma odontogénico es una neoplasia benigna, poco frecuente, de origen mesenquimal proveniente del órgano dentario, es localmente invasivo y no hace metástasis. Su localización más frecuente es a nivel de la mandíbula y poco frecuente en el maxilar. Objetivo: describir las características que presenta un mixoma odontogénico de larga data en el maxilar. Presentación del caso: paciente de sexo masculino de 23 años de edad, soltero, de profesión comerciante, acude a la Catedra de Patología Bucal de la Facultad de Odontología de la Universidad Nacional de Asunción por presentar una deformidad en la región facial del lado derecho, presente desde la infancia con crecimiento lento sin sintomatología dolorosa. Se realizó una biopsia incisional, tomando una muestra de más de 1 cm de la capsula tumoral para su estudio histopatológico; a partir de la cual se informa sobre un tumor odontogénico mesenquimal compatible con el mixoma odontogénico. Se realizó el tratamiento de una maxilectomía con márgenes de seguridad y el estudio anatomopatológico de todo el tumor extirpado confirmó el diagnóstico de Mixofibroma odontogénico de 2,5 cm de diámetro máximo. Conclusión: un diagnóstico precoz de tumores como los mixomas, que son de crecimiento lento e infiltrante, podría garantizar terapéuticas menos agresivas e invasivas como las del caso presentado, otorgando así mejor pronóstico como calidad de vida a los pacientes.


Introduction: Odontogenic myxoma is a rare benign neoplasm of mesenchymal origin originating from the dental organ, it is locally invasive and does not metastasize. Its most frequent location is at the level of the mandible and infrequently in the maxilla. Objective: To describe the characteristics of a long-standing odontogenic myxoma in the maxilla. Presentation of the case: Male patient, 23 years of age, single, businessman, came to the Department of Oral Pathology of the Faculty of Dentistry of the National University of Asuncion for presenting a deformity in the facial region on the right side, present since childhood with slow growth and no painful symptomatology. An incisional biopsy was performed, taking a sample of more than 1cm of the tumor capsule, for histopathological study; reporting a mesenchymal odontogenic tumor compatible with odontogenic myxoma. A maxillectomy treatment with safety margins performed and the anatomopathological study of the entire excised tumor confirmed the diagnosis of odontogenic myxofibroma with a maximum diameter of 2.5 cm. Conclusion: An early diagnosis of tumors such as myxomas, which are slow-growing and infiltrative, could guarantee less aggressive and invasive therapies such as those in the case presented, thus providing patients with a better prognosis and quality of life.

ABSTRACT

A 52?year?old woman presented with dysarthria and right?sided weakness in her upper and lower extremities prompting thrombolytic therapy with mild resolution of symptoms. Further work?up revealed (the source) a left ventricular myxoma on the chordae tendinae of the posterior medial papillary muscle, confirmed with transesophageal echocardiography and pathology. Herein, we present a rare case of embolic stroke from a myxoma originating on the chordae tendinae. To the best of our knowledge, the literature on the location and presentation of this tumor as seen in our patient is sparse in contemporary findings.

ABSTRACT

Cardiac masses are rare, and they pose an interesting diagnostic and therapeutic challenge. The differentials vary from tumours – both primary and secondary, thrombus, infective vegetations, artifacts to cysts. They can present with obstructive symptoms, embolisation, constitutional symptoms or pericardial effusions. Multimodality imaging with echocardiogram, computed tomography (CT) and magnetic resonance imaging (MRI) help in diagnosis. Complete surgical resection is often the modality of choice in cases of tumours. Thrombolysis or surgical extraction is suitable in cases of thrombus in the right heart.

ABSTRACT

Introduction: Odontogenic tumors (OTs) are rare and account for around 1% of jaw lesions including tumor and tumor-like lesions. OTs are a diverse category of lesions, displaying different inductive interactions. Although some are hamartomas, others are benign and malignant neoplasms with varying degrees of aggressiveness. Materials and Methods: We plan to review the histopathological aspects of OTs because of their diverse properties. At a tertiary medical and dental institute in Pune, India, we studied 28 cases of OTs over 2 years, from 2013 to 2015. Results: The most common forms of OTs were ameloblastoma (42.86%) and odontogenic keratocyst (21.15%). The highest number of OTs was found in the 21–30-year-old age group, with an even gender distribution. Conclusion: Ameloblastoma is the most common OT, accounting for roughly one-quarter of all jaw tumors. The majority of OTs occurs in young people aged 20–40 years. Fortunately, malignant OTs are extremely rare.

ABSTRACT

Las neoplasias cardíacas se dividen en tumores primarios y secundarios; estos últimos son 30 veces más frecuentes. La mayoría de las neoplasias cardíacas son benignas y dentro de este grupo destaca el mixoma auricular. La presentación clínica es muy variable en relación con su ubicación, tamaño y movilidad, y los hallazgos a nivel de las pruebas complementarias son inespecíficos. Dado que su historia natural muchas veces pasa inadvertida, el mixoma puede culminar en la obstrucción auriculoventricular, obstrucción del tracto de salida ventricular o incluso embolias sistémicas; de esta forma, es el causante de sintomatología severa como síncope, insuficiencia cardíaca y muerte súbita cardíaca. Su manifestación clínica como un síncope es bastante frecuente. Se expone el caso de un paciente de sexo masculino de 81 años que consultó en el servicio de urgencias por un síncope. Durante su valoración, se identificó el mixoma auricular como etiología de este.


Cardiac neoplasms are divided into primary and secondary tumors, the latter are 30 times more frequent. Most are benign and within this group the atrial myxoma stands out. The clinical presentation is very variable in relation to its location, size and mobility, and the findings in the complementary tests are nonspecific. Since its natural history often goes unnoticed, the myxoma can culminate in atrial ventricular obstruction, ventricular outflow tract obstruction or even systemic embolism, causing severe symptoms such as syncope, heart failure and sudden cardiac death. Its clinical manifestation as syncope is quite common. The case of an 81-year-old male patient who consulted at the emergency department for syncope is presented, in which the atrial myxoma was subsequently identified as the etiology of the event during the further evaluation.


As neoplasias cardíacas dividem-se em tumores primários e secundários, estes últimos são 30 vezes mais frequentes. A maioria são benignas e dentro deste grupo destaca-se o mixoma auricular. A apresentação clínica é muito variável em relação com sua localização, tamanho e mobilidade, e os achados a nível dos testes complementares são inespecíficos. Dado que a sua história natural muitas vezes passa despercebida, o mixoma pode culminar na obstrução aurículo-ventricular, obstrução do tracto de saída ventricular ou mesmo embolias sistémicas, sendo assim o causador de sintomatologia severa como síncope, insuficiência cardíaca e morte súbita cardíaca. Sua manifestação clínica como síncope é bastante comum. Apresenta-se o caso de um paciente de sexo masculino de 81 anos que consultou no serviço de urgências para um síncope. Durante a sua avaliação, se identificou mixoma auricular como etiologia deste
