Tratamento cirúrgico de hemangioma infantil nasal e labial na fase involuída: relato de caso / Surgical treatment of infantile nasal and labial hemangioma in the involuted phase: a case report

Hemangioma infantil (HI) é o tumor vascular mais comum e a neoplasia benigna mais frequente da infância, com maior incidência no sexo feminino e na população branca. Quase 60% dos casos ocorrem em cabeça e pescoço, sendo o tratamento ativo durante a fase proliferativa mais frequentemente indicado, em decorrência dos possíveis problemas funcionais e do potencial desfigurante. Relatamos um caso de paciente com hemangioma infantil involuído de ponta nasal e lábio superior, tratado de forma expectante durante a infância, submetida à correção da deformidade residual com técnicas de rinoplastia, associado à zetaplastia e lipoenxertia do lábio superior com bom resultado e satisfação do paciente.

Infantile hemangioma (IH) is the most common vascular tumor and the most frequent benign neoplasm in childhood, with the highest incidence in females and the white population. Almost 60% of cases occur in the head and neck, and active treatment during the proliferative phase is the most frequently indicated, due to possible functional problems and disfiguring potential. We report a case of a patient with involute infantile hemangioma of the nasal tip and upper lip, treated expectantly during childhood, submitted to residual deformity correction with rhinoplasty techniques, associated with zetaplasty and upper lip grafting with good results and patient satisfaction.

Tratamiento multidisciplinar del leimiosarcoma de vena cava inferior / Multidisciplinary treatment of leiomyosarcoma of inferior cava

Resumen Introducción Los leiomiosarcomas de la vena cava inferior son tumores raros, sólo hay 300 casos descritos en la literatura. Su incidencia es mayor en mujeres, suelen aparecer entre los 50-60 años, y presentan una progresión lenta y mal pronóstico. Los síntomas son inespecíficos haciendo que el diagnóstico se realice de forma tardía, éste se realiza mediante pruebas de imagen y biopsia guiada. Caso clínico Se presenta el caso de un varón de 73 años con diagnóstico de leiomiosarcoma de la vena cava inferior, como hallazgo incidental en TC de control, tratado mediante radioterapia neoadyuvante, cirugía y radioterapia intraoperatoria. Discusión El único tratamiento que ha descrito modificaciones en la supervivencia es la cirugía. El papel de la adyuvancia y neoadyuvancia en estos tumores es muy controvertido. La elección de la actitud terapéutica dependerá de la localización del tumor, tamaño, la relación con estructuras adyacentes y la presencia de circulación colateral.

Introduction Leiomyosarcomas of the inferior vena cava are rare tumors, with fewer than 300 cases reported. Its incidence is higher in females, usually appear in the sixth decade and they have a slow-growing and poor prognosis. Symptoms are generally non-specific. Diagnosis is made with imaging studies and guided biopsy. Clinical Case We report a case of a 73-year-old male patient with leimyosarcoma of the inferior vena cava treated by neoadjuvant radiotherapy, surgery and intraoperative radiotherapy. Discussion Surgery is the only treatment that can improve the survival. The role of the adjuvancy and neoadjuvancy is very controversial. Surgical management is determined by the location of the tumour, the relationship with adjacent structures and the presence of collateral veins.

Pelvic Intravenous Leiomyomatosis - Case Report / Leiomiomatose intravenosa pélvica - caso clínico

Abstract Introduction Intravenous leiomyomatosis is a benign and rare condition that can result in cardiac events with fatal outcomes when left untreated. Intravenous leiomyomatosis is probably underestimated because the diagnosis is easily missed. We present a case of an intravenous leiomyomatosis without extra-pelvic involvement, with a brief review of this pathology. Case Report 46-year-old woman submitted to hysterectomy and bilateral adnexectomy because of a pelvic mass detected in ultrasound. During the surgery, intravenous leiomyomatosis diagnosis was suspected. Pathological analysis confirmed this suspicion. Further imaging exams were performed without detecting any anomalies related to this condition. The patient remained with no evidence of disease after one year of follow-up. Conclusion Intravenous leiomyomatosis is a rare condition that can lead to serious complications. Early diagnosis followed by an appropriate treatment is very important to patient outcome, and underdiagnoses can be counteracted if the gynecologist is aware of this entity.

Resumo Introdução A leiomiomatose intravenosa é uma condição benigna, rara, que pode resultar em eventos cardíacos, podendo ser fatal quando não tratada. Esta patologia está provavelmente subestimada, uma vez que facilmente não é diagnosticada. Neste artigo, apresentamos um caso de leiomiomatose intravenosa sem envolvimento extrapélvico, com uma breve revisão da patologia. Relato de Caso Mulher de 46 anos de idade, submetida a histerectomia e anexectomia bilateral após detecção ecográfica de massa pélvica. Durante a cirurgia, houve a suspeita de leiomiomatose intravenosa, e o exame anátomo-patológico confirmou o diagnóstico. A paciente foi submetida a outros exames de imagem, não sendo detectada qualquer anomalia relacionada com a patologia. Após um ano de followup, a paciente manteve-se sem evidência de doença. Conclusão A leiomiomatose intravenosa é uma condição rara que pode levar a complicações graves. O diagnóstico precoce e o tratamento adequado são muito importantes para o prognóstico da paciente, e os subdiagnósticos podem ser evitados se o ginecologista estiver ciente dessa entidade.

Case for diagnosis

Intravascular papillary endothelial hyperplasia is a benign vascular lesion caused by proliferation of endothelium. It is reactive to thrombotic or inflammatory stimuli in the vessel wall.We report the case of a 14-yearold male patient with a violet-colored erythematous tumoral lesion of progressive growth in the occipital region. The diagnosis of intravascular papillary endothelial hyperplasia (IPEH) was confirmed by clinical and histopathological findings. Total lesion exeresis was performed with no recurrence up to date. IPEH presents clinical importance due to its clinical and histological resemblance to angiosarcoma. In order to differentiate it from angiosarcoma, distinguishing features of the benign disease should be considered, such as lack of cellular atypia and rare mitotic activity.Prognosis is good.

Leiomiomatose endovenosa: abordagem anestésica a propósito de um caso clínico / Anesthetic approach for a clinical case of intravenous leiomyomatosis: case report / Leiomiomatosis endovenosa: abordaje anestésico a propósito de un caso clínico

JUSTIFICATIVA E OBJETIVOS: Descrevemos a abordagem anestésica a propósito de um caso clínico de leiomiomatose endovenosa, com invasão da veia cava inferior e extensão à aurícula direita, tratada com êxito por meio de abordagem cirúrgica. RELATO DE CASO: Doente do sexo feminino, 45 anos, aparentemente estável até duas semanas antes da ida à urgência, altura em que iniciou cansaço e dispneia. Fez ecocardiograma, no qual se constatou massa intracardíaca. Por isso, fez tumorectomia eletiva na transição veia cava-aurícula direita e ventrículo direito. À histologia, a peça operatória evidenciou sugestividade de leiomioma uterino. Posteriormente, para avaliar a extensão, fez-se tomografia computadorizada, que demonstrou extensão à veia cava inferior e ao ovário esquerdo. Foi então proposta para histerectomia total, anexetomia esquerda e salpingectomia direita, remoção de leiomioma intravenoso e colocação de filtro definitivo na veia cava inferior. Neste artigo descreve-se a abordagem anestésica com particular ênfase na correção das necessidades hídricas, bem como na evolução no pós-operatório, e salientam-se possíveis contributos à abordagem futura de casos semelhantes. CONCLUSÕES: O diagnóstico pré-operatório de leiomiomatose endovenosa é extremamente difícil. O tratamento consiste na extração cirúrgica. Esse procedimento envolve importantes perdas hemáticas e, por isso, condicionou a preparação pré-operatória. No intraoperatório a fluidoterapia foi fulcral e a monitoração invasiva se assumiu como preponderante no auxílio do equilíbrio hidroeletrolítico da doente. A existência de um laboratório de análises clínicas acessível e com resposta rápida e avaliação gasimétrica próxima foi determinante. A unidade de cuidados intensivos equipada com ventilador para os cuidados pós-operatórios revelou-se outra necessidade decorrente deste caso.

BACKGROUND AND OBJECTIVES: The aim of this study was to describe the anesthetic approach in a case of intravenous leiomyomatosis with invasion of the inferior vena cava and extension to the right atrium, successfully treated with surgical approach. CASE REPORT:Female patient, 45 years old, apparently stable until two weeks before the admission to the emergency department with complaints of fatigue and dyspnea. Echocardiogram was performed, which detected an intracardiac mass. Therefore, elective tumorectomy was performed in the vena cava-right atrium and right ventricle transition. Histological examination of the specimen suggested uterine leiomyoma. Subsequently, to assess the extent, computed tomography was done and showed extension to the inferior vena cava and left ovary. Hysterectomy, left adnexectomy and right salpingectomy, removal of intravenous leiomyoma, and permanent filter placement in the inferior vena cava were proposed. In this article, we describe the anesthetic approach with particular emphasis on the correction of fluid requirements, as well as postoperative evolution, and we highlight possible contributions to future approach of similar cases. CONCLUSIONS: Preoperative diagnosis of intravenous leiomyomatosis is extremely difficult. Treatment consists of surgical removal. This procedure involves major blood loss and, therefore, preoperative preparation was conditioned: intraoperative fluid therapy was central and invasive monitoring considered predominant to assist in fluid and electrolyte balance of the patient; the existence of a clinical laboratory accessible and with rapid response and blood gas assessment was crucial; the intensive care unit equipped with ventilator for postoperative care proved to be another requirement resulting from this case.

JUSTIFICATIVA Y OBJETIVOS: Describimos aquí el abordaje anestésico a propósito de un caso clínico de leiomiomatosis endovenosa, con invasión de la vena cava inferior y extensión a la aurícula derecha, que tuvo éxito por medio de un abordaje quirúrgico. RELATO DE CASO: Mujer enferma, de 45 años, aparentemente estable hasta dos semanas antes de su llegada a urgencias, en que debutó con cansancio y disnea. Hizo el ecocardiograma en que se comprobó masa intracardiaca. Por eso, se procedió a la tumorectomía electiva en la transición vena cava-aurícula derecha y ventrículo derecho. En la histología, la pieza operatoria mostró una sugestión de leiomioma uterino. Posteriormente, para evaluar la extensión, se realizó la tomografía computadorizada, que arrojó una extensión a la vena cava inferior y al ovario izquierdo. Entonces se propuso la histerectomía total, anexetomía izquierda y salpingectomía derecha, retirada de leiomioma intravenoso y colocación de filtro definitivo en la vena cava inferior. En este artículo, describimos el abordaje anestésico dándole un énfasis particular a la corrección de las necesidades hídricas, como también a la evolución en el posoperatorio, destacando posibles aportes al abordaje futuro de casos parecidos. CONCLUSIONES: El diagnóstico preoperatorio de leiomiomatosis endovenosa es extremadamente difícil. El tratamiento consiste en la extracción quirúrgica. Ese procedimiento involucra importantes pérdidas hemáticas y por eso, condicionó la preparación preoperatoria. En el intraoperatorio la fluidoterapia fue fundamental y la monitorización invasiva se asumió como preponderante en el auxilio del equilibrio hidroelectrolítico del enfermo. La existencia de un laboratorio de análisis clínicos accesible y con una respuesta rápida y una evaluación de la gasometría fue determinante. La unidad de cuidados intensivos equipada con ventilador para los cuidados postoperatorios fue otra necesidad originada por este caso.

Hemangiopericitoma: reporte de 3 casos / Hemangiopericytoma: a report of 3 cases and a literature review

Introduction: The hemangiopericytoma (HPC) is a rare vascular tumor that can be potentially malignant. It can be found in any part of the body but usually in the lower extremities or the retroperitoneum. Because its potential malign nature, it's necessary to perform oncological resections when are operating on. Methods: Three cases are presented. Results: One of them was located at the sacrococcigeal space, being the second reported case in the international literature. The other cases were in cervical and adrenal localization.

Introducción: El hemangiopericitoma (HPC) es un tumor vascular raro y potencialmente maligno que puede localizarse en cualquier parte del cuerpo, con mayor frecuencia en extremidades inferiores y retrope-ritoneo. Su potencial malignidad da la necesidad de realizar resecciones oncológicas al operarlos. Material y Método: Se presentan tres casos tratados por nuestro grupo. Resultados: Uno de ellos tiene localización sacra siendo, hasta donde sabemos, el segundo en ser publicado. Otro es de localización suprarrenal y el tercero es cervical.

Relevancia de la medicina nuclear en el diagnóstico y tratamiento del paraganglioma maligno / Relevance of nuclear medicine in the diagnosis and treatment of malignant paraganglioma

Introducción: Los paragangliomas son tumores del tejido cromafín caracterizados por la síntesis o secreción de catecolaminas, en los que el tratamiento depende de su extensión y características funcionales. Dentro de la evaluación diagnóstica anatómica y funcional de este padecimiento, los métodos de imagen de medicina nuclear sobresalen por su utilidad. Caso clínico: Paciente con paraganglioma a nivel de la bifurcación de la aorta en quien el diagnóstico se realizó por estudios de laboratorio, imagenología y medicina nuclear. Se llevó a cabo centelleografía con un análogo de norepinefrina, la metayodobencilguanidina marcada radiactivamente (131I-MIBG), que demostró funcional y específicamente la presencia de tejido adrenérgico neoplásico y su extensión extratumoral. Complementariamente se efectuó tomografía por emisión de positrones fusionada con tomografía computarizada, utilizando un análogo radiactivo de la glucosa que localizó la actividad extratumoral a nivel óseo. Los estudios de medicina nuclear permitieron concluir que se trataba de un paraganglioma maligno con metástasis óseas. El tratamiento incluyó resección quirúrgica del tumor y ablación del tejido tumoral residual y de los focos metastásicos con radioterapia interna mediante 131I-MIBG. El tratamiento radioterapéutico fue posible dada la capacidad del tumor y las metástasis de concentrar el análogo hormonal radiactivo. Conclusiones: Ante casos de paragangliomas, además de la localización del tumor y la evaluación de las alteraciones bioquímicas, es indispensable la evaluación funcional que brinda la medicina nuclear para la realización de un diagnóstico y tratamiento adecuados.

BACKGROUND: Paragangliomas are neoplasms of the chromaffin tissue characterized by the synthesis and/or secretion of catecholamines. Their treatment depends on the extension and functional characteristics of the tumor. In this pathology, the anatomic and functional diagnostic evaluations provided by nuclear medicine imaging studies have significant usefulness. CLINICAL CASE: A 34-year-old male was diagnosed with a paraganglioma at the level of the aortic bifurcation by means of laboratory tests, imaging studies and nuclear medicine studies. Nuclear medicine was carried out with a scintigraphy with a norepinephrine analog, radioactive meta-iodo-benzyl-guanidine (131I-MIBG), which demonstrates functionally and specifically the presence of neoplastic adrenergic tissue and extratumoral extension. In addition, a positron emission tomography coupled with computed tomography with a radioactive analog of glucose locates the extratumoral activity at bone level. Nuclear medicine studies allow the diagnosis of a malignant paraganglioma with presence of bone metastasis. The therapy includes surgical removal of the tumor and ablation of residual malignant tissue and metastatic lesions by radiotherapy with 131I-MIBG. Radiotherapeutic treatment was possible due to the capacity of the tumor to uptake and to concentrate the radioactive hormonal analog. CONCLUSIONS: In cases of paraganglioma, in addition to the localization of the tumor and the evaluation of biochemical alterations, it is indispensable to obtain anatomic and functional evaluation provided by nuclear medicine studies in order to achieve appropriate diagnoses and treatment.

Reconstruções arteriais realizadas em pacientes submetidos à ressecção de neoplasias com acometimento vascular / Arterial reconstruction in patients undergoing resection of neoplasia with vascular involvment

A braquiterapia de alta taxa de dose (BATD) associada à radioterapia externa (RT) representa uma boa opção para o tratamento do câncer da próstata, porém existem poucos relatos sobre sua toxidade. O nosso objetivo foi avaliar a toxicidade gastrointestinal (GI), genitourinária (GU) e sexual em 37 pacientes com adenocarcinoma de próstata; e conseguir toxicidade equivalente ou inferior à radioterapia conformada. Os pacientes receberam duas frações de BATD com doses de 7 a 8,5 Gy e 45 Gy de RT. A toxicidade foi avaliada pela classificação do Radiation Therapy Oncology Group e de Stone. As toxicidades GI e GU foram mais observadas em sua forma mais leve. A impotência sexual ocorreu na maioria dos pacientes. O tratamento apresentou toxicidade aceitável e semelhante à radioterapia conformada / High dose rate brachytherapy (HDR) in association with external beam radiotherapy (EBRT) is a good treatment option for prostate cancer, but there are few data about it’s toxicity. Our purpose was to analyze gastrointestinal (GI), genitourinary (GU) and sexual toxicities of 37 patients with prostate cancer and have a smaller or equal toxicity, compared with conformal radiotherapy. The patients were treated with two fractions of HDR with doses ranging from 7 Gy to 8.5 Gy, followed by 45 Gy of EBRT. The toxicity was scored according to the Radiation Therapy Oncology Group scales and the Stones classification. The GI and GU toxicities were mild in most cases. The sexual impotence was observed in most patients. The treatment presented acceptable toxicitiy, similars to conformal radiotherapy...

Hipofosfatemia revertida al extirpar hemangioendotelioma compuesto del dedo mayor del pie / Reversion of hypophosphatemia after the excision of a composite hemangioendothelioma in the great toe

We report a 43 years old male admitted to the hospital for progressive lumbar pain, lasting 20 years, that caused severe disability. On admission the patient had a serum phosphate of 2 mg/dl, an urine phosphate excretion over 300 mg/dl and serum alkaline phosphatases over 750 U/L. Serum intact parathormone was normal and tubular maximum phosphorus/glomerular filtration was 0.7 mg/dl. Bone scintigraphy showed an increased radionuclide uptake in condro-costal joints. Bone densitometry showed femoral osteoporosis. A violet colored mass was detected in a great toe. It was removed and the pathological diagnosis was a composite hemangioendothelioma. After tumor excision, serum phosphate levels returned to normal values and symptoms disappeared within 15 days.

Intraoperative radiation therapy as an adjunctive therapy for huge and highly vascular parasagittal meningiomas

This case presents a 34-year-old man who had a huge parasagittal meningioma. Initial treatment consisted of preoperative external carotid artery embolization and partial tumor resection. During the resection, we found that the tumor invaded the adjacent calvarium, and due to massive hemorrhage, total removal of the tumor was impossible. The patient was treated with intraoperative radiation therapy (IORT) (25 Gy via 16 MeV) as an adjunctive therapy. Eight months after IORT, we were able to remove the tumor completely without surgical difficulties. IORT can be considered an useful adjunctive therapy for the superficially located, huge, and highly vascular meningioma.

Unusual abdominal tumors with intracardiac extension. Two cases with successful surgical resection

Abdominal tumors that can grow through vascular lumen and spread to the right heart are rare. Although these tumors have different histologic aspects, they may cause similar abdominal and cardiac symptoms and are a serious risk factor for pulmonary embolism and sudden death when they reach the right atrium and tricuspid valve. The best treatment is radical surgical resection of the entire tumor using cardiopulmonary bypass with or without deep hypothermia and total circulatory arrest. We report the cases of two patients, the first with leiomyosarcoma of the inferior vena cava and the other with intravenous leiomyomatosis of the uterus that showed intravascular growth up to right atrium and ventricle, who underwent successful radical resection in a one-stage procedure with the use of cardiopulmonary bypass. We discuss the clinical and histologic aspects and imaging diagnosis and review the literature
