ABSTRACT

Odontogenic myxomas (OMs) are rare, benign, slow-growing tumors that may arise in the maxilla. They are known to have a female predilection and present as a painless mass commonly in the second or third decade of life, comprising 3-6% of all odontogenic tumors. They show a locally aggressive behavior, are radioresistant tumor and hence the need for early recognition and surgical resection. A high rate of recurrence has also been noted owing to its infiltrative pattern of growth and lack of capsule. Clinical and radiological aspects of maxillary OMs are not conclusive hence it is necessary to have a histopathological exam for the final diagnosis. We present a case of OM involving the maxilla in a 51-year-old female patient. The various histopathological differentials are also discussed.

ABSTRACT

INTRODUCCIÓN. Los tumores primarios del corazón pueden ser malignos o benignos, mientras que los tumores secundarios son siempre metastásicos. El 75 por ciento de los tumores primarios son benignos y de localización endocavitaria, la mayoría es del tipo mixoma, sobre todo en los adultos. MÉTODOS. De un total de 2925 pacientes operados con circulación extracorpórea entre enero de 1986 y enero del 2006 en el Hospital Hermanos Ameijeiras, se seleccionaron 30 expedientes clínicos de pacientes con diagnóstico histopatológico de mixoma cardíaco. Para el análisis de los resultados se aplicaron cálculos de incidencia. A las variables se aplicaron porcentajes, medias y desviación estándar. RESULTADOS. Diecinueve pacientes fueron del sexo femenino y 11 del masculino, con rango de edad entre 15 y 66 años (media, 44 años). Los elementos clínicos desde el punto de vista semiológico fueron muy variados, y predominaron las palpitaciones y la disnea en el 83 por ciento y 73 por ciento de los pacientes, respectivamente. El intervalo de aparición de los síntomas fue desde 1 mes hasta 92 meses (media, 15 meses). El ecocardiograma confirmó el 100 por ciento del diagnóstico en los pacientes. La localización más frecuente de los mixomas fue la aurícula izquierda (80 por ciento de los casos). A todos los pacientes se les practicó la exéresis del tumor y su base de implantación. La mortalidad observada fue del 6,6 por ciento. CONCLUSIONES. La incidencia de esta enfermedad fue del 1,2 por ciento de todos los pacientes operados en este tiempo. La proporción sexo femenino-masculino fue de 2:1. El ecocardiograma constituye la piedra angular del diagnóstico positivo de los mixomas cardíacos. La mortalidad en la serie estuvo dentro de los rangos documentados en la literatura médica internacional(AU)


INTRODUCTION: Heart primary tumors may be maligns or benigns, whereas the secondary tumors always are of metastatic origin. The 75 percent of primary tumors are benigns and of a endocavitary localization, most are of myxoma type mainly in adult people. METHODS: From a total of 2925 patients were operated on using extracorporeal circulation between January, 1986 and January, 2006 in Hermanos Ameijeiras Clinical Surgical Hospital, thirty clinical records were selected from patients histologically diagnosed with cardiac myxoma. For results analysis we applied incidence estimates. In variables percentages, means and standard deviation were used. RESULTS: A total of 19 patients were females and 11 were males with an age range between 15 and 66 years (mean, 44 years). Clinical elements from the symptomatology point of view were varied and with a predominance of palpitations and dyspnea in 83 percent and 73 percent of patients, respectively. Appearance symptoms interval was from 1 month to 92 months (mean, 15 months). Echocardiogram confirmed the 100 percent of diagnosis in patients. The more frequent myxomas localization was the left atrium (80 percent of cases). All patients underwent tumor exeresis and its implantation basis. Mortality observed was of 6,6 percent. CONCLUSIONS: Incidence of this disease was of 1,2 percent of all patients operated on in that period. Female-male sex ratio was of 2:1. Echocardiogram is the cornerstone of the positive diagnosis of cardiac myxomas. The mortality of this series was within the documented ranges in international medical literature(AU)

ABSTRACT

El mixoma odontogénico se considera una neoplasia benigna, poco frecuente, de consistencia firme y gelatinosa, de crecimiento lento con potencial infiltrativo que produce expansión de la cortical con extensa destrucción ósea y alto índice de recidiva. De origen ectomesenquimàtico, probablemente derivado del órgano dentario. No existe una predilección particular por sexo, y si una ligera preferencia por presentarse en mandíbula, generalmente asintomàtico. Se presenta una paciente femenina de dieciséis años de edad, color de la piel blanca, con antecedentes de salud, que acude a consulta de cirugía màxilo facial por aumento de volumen de hemicara derecha, sin otra sintomatología acompañante. Al examen físico se observa aumento de volumen en región maxilar derecha. Al realizar tomografía axial computarizada se observó lesión hiperdensa que ocupaba todo el seno maxilar derecho, con àreas de mayor densidad, que respetaba el hueso que conforma el piso de la órbita. Bajo anestesia general naso traqueal se le realizó hemimaxilectomia, retirada de tumor y colocación de prótesis inmediata obturadora. Después de un año de evolución clínica y radiogràfica se colocó la prótesis definitiva, sin presencia de recidiva tumoral(AU)


An odontogenic myxoma is a uncommon benign neoplasm of a gelatinous and solid consistency, of lengthy growing with a infiltration potential producing an cortex expansion of with and extend bone destruction and a high rate of relapse. Its origin is ectomesenchymal, probably derived from dental organ. There is not a particular sexual preference, but a slight one by be present in mandible and generally asymptomatic. This is the case of a female white patient aged 16, with health backgrounds referred to Maxillofacial consultation due to an of right hemifacial increase without another accompanying symptomatology. At physical examination there is an increase in volume of right maxillary region. In computerized axial tomography (CAT) a hyperdense lesion occupying all right maxillary sinus with areas of higher density without affecting the orbit floor bone. Under nasotracheal general anesthesia a hemimaxillotomy was carried out, tumor removal and obturator immediate prosthesis placing. At a year of clinical course and radiography definitive prosthesis was placed without tumor relapse(AU)

ABSTRACT

Background: Cardiac tumors are very uncommon at all ages. There are important clinical differences between children and adults in the behavior of these tumors. Aim: To compare the behavior of primary and secondary cardiac tumors, from fetal age to adults. Patients and Method: Multicentric retrospective analysis of 38 children and adults with cardiac tumors, evaluated with echocardiography between January 1995 and August 2001. Medical records, echocardiographic and radiological examinations, surgical protocols and pathologic examinations were reviewed. Follow-up was obtained through data on medical records or calling patients by telephone. Results: Tumors were diagnosed in 38 patients (13 children and 25 adults), from a total of 31.800 echocardiograms. In children the diagnosis was made by fetal, transthoracic or transesophageal echocardiography in 23.6 percent and 8 percent of cases, respectively. Eighty five percent were primary (10 benign and 1 malignant) and 15 percent, secondary tumors. Fifty four percent were rhabdomyomas and 75 percent regressed spontaneously. Seventy seven percent were symptomatic and 31 percent were treated with surgery. During a follow up of 44±35 months, 31 percent of patients died. In adults, 76 percent of tumors were diagnosed by transthoracic and 20 percent by transesophageal echocardiography. Seventy six percent were primary (18 benign and 1 malignant) and 24 percent secondary tumors. Fifty six percent were myxomas. Ninety two percent were symptomatic and 84 percent were treated surgically. Twenty percent of patients died in the early postoperative period. No adult patients had a follow-up. Conclusions: Rhabdomyomas were solely found in children. In adults, myxomas are the predominat cardiac tumors. Primary and metastasic malignant tumors are observed both in children and in adults.

Los más frecuentes son los mixomas de localización auricular. Objetivo: Describir las características de los tumores cardíacos certificados por anatomía patológica. Material y método: Estudio descriptivo-retrospectivo. Período enero 1984-junio 2004. Información obtenida de la base de datos del equipo de Cirugía Cardiotorácica, fichas clínicas y registros de anatomía patológica. Se describe sexo, edad, características clínicas, método diagnóstico, tratamiento quirúrgico, anatomía patológica, evolución y seguimiento. Resultados: Total 10 casos, 8 hombres. Edad promedio 42.7 años. Síntomas cardiovasculares 8 pacientes, 1 asintomático y 1 corresponde a necropsia. Manifestación clínica más frecuente disnea en 7. Cuatro pacientes en capacidad funcional mayor o igual a III al momento del diagnóstico. Principal método diagnóstico: ecocardiograma transtorácico. Se realizó tratamiento quirúrgico en 9 pacientes, en 5 resección y en 4 resección y cierre del defecto residual con parche. En un paciente portador de insuficiencia aórtica, se realizo cirugía de reemplazo valvular aórtico y resección del tumor, todos con circulación extracorpórea. La localización fue en 9 casos auricular, 8 en aurícula izquierda y uno ventricular izquierdo y todos fueron mixomas. Presentaron morbilidad 3 pacientes, un neumotórax, una dehiscencia esternal y un hematoma de la esternotomía. No hubo reoperaciones ni mortalidad. En el seguimiento todos mejoraron su capacidad funcional. Conclusiones: Los tumores cardíacos son infrecuentes, siendo los más habituales los mixomas auriculares izquierdos. Presentan clínica inespecífica y son de baja morbimortalidad operatoria.

ABSTRACT

This is the author's experience with odontogenic tumours in Jamaica during the 15-year period, 1980-1995, with special emphasis on the clinicopathological presentation, radiology and outcome of treatment. A retrospective review of histopathological reports, radiographs and case notes of patients with jaw tumours presenting to the Kingston Public Hospital and Cornwall Regional Hospital (the two hospitals in Jamaica with a maxillofacial surgery department) are presented. The study included 70 patients with histologically confirmed odontogenic tumours out of a total of 293 with tumours of the mouth and jaw, of which 123 were of odontogenic origin. We recorded the following; ameloblastoma (n = 47, 67, M:F = 1:1), recurrent ameloblastoma (n = 12, 17.1) odontogenic myxoma (n = 3, 4.3, M:F = 2:1), odontongenic fibroma (n = 2, 2.9, both female), adenomatoid odontogenic tumour (n = 3, 4.3 M:F = 1:2) ameloblastic fibroma (n = 2, 2.9, M:F = 1:1) and ameloblastic carcinoma (n = 1, 1.4, a male). Of all these tumours, only ameloblastomas recurred. Further research is required to explain the high incidence of ameloblastoma, and why it has a predilection for people of low socioeconomic status in Jamaica

ABSTRACT

Los tumores de los maxilares de origen odontogénico son aquellos que se originan a partir de la células epiteliales y mesenquimales especializadas que forman los tejidos del diente. En la patología oral y máxilo facial tenemos tumores de alta agresividad, tales como el Mixoma, el Tumor Odontogénico Epitelial Calcificante y el Ameloblastoma, importantes a tener en cuenta para el diagnóstico diferencial. Los autores reportan cuatro casos de mixoma en los maxilares, de los cuales dos fueron ubicados en la mandíbula y los restantes en el maxilar superior. El uso del colgajo de Weber-Ferguson para la resección de los Mixomas del maxilar superior fueron los elegidos debido al comportamiento y tamaño de dicho tumor. Mientras que los Mixomas mandibulares fueron resecados marginalmente debido al menor compromiso de estructuras mandibulares afectadas

ABSTRACT

Las manifestacines clínicas oftalmológicas del mixoma cardiaco son muy raras y cuando se sospeche de enfermedad embolígena debe de tomarse en cuenta en el diagnóstico diferencial. El presente caso ejemplifica cómo el mixom auricular puede ser manifestación simultánea de obstrucción de arteria central de la retina y de evento vascular cerebral. Se discuten las diversas causa de enfermedad embolígena y se lleva a cabo un ejercicio clínico para diferenciar al mixoma auricular de otras enfermedades sistémicas que nos pudieran dar la misma sintomatología neuro-oftalmológica

ABSTRACT

Cardiac myxomas are rare cardiac lesions, though they are the commonest tumours of the heart. Seventeen cases of cardiac myxomas have been operated during the last one decade. Exertional dyspnoea, palpitation and chest pain were the main presenting symptoms. Echocardiographic assessment was the only definitive diagnostic investigation required prior to surgery. Early surgical excision was planned in all the cases. Irrespective of the exposure techniques, removal of the tumour with wide excision of its base was practised. There was one early death due to low cardiac output in a patient brought in a shock like state. Follow up study has revealed 14 patients in NYHA class I and two patients are having class II symptoms. Periodic echocardiographic follow up study has not revealed any recurrence till date. It is concluded that an early diagnosis and surgery gives excellent long term results in these cases.

ABSTRACT

Se describe el caso de un mixoma auricular izquierdo, en una mujer joven, como causa de embolía cerebral y de la arteria central de la retina, como una patología poco frecuente, en una de sus formas de presentación, planteándose incluso la posibilidad diagnóstica de una mesenquimopatía (Lupus), con manifestaciones centrales. Diagnosticada con métodos no invasivos, comprobado en acto quirúrgico y certificado al informe anátomo-patológico. A pesar del corto tiempo de seguimiento post. op., ha tenido una buena evolución neurológica sin señales de recidiva. Se revisó la literatura actual, se analizan los criterios clínicos y de laboratorio para el diagnóstico, como también la conducta de tratamiento y seguimiento, con el propósito de enriquecer la casuística nacional en relación a esta patología
