ABSTRACT

Las lesiones de la región nasofrontal en los niños son un reto diagnóstico debido a su rareza, y su potencial comunicación con el sistema nervioso central también aumenta su complicaciones. Dentro de las principales entidades de esta región se encuentran los quistes dermoides, los gliomas nasales y los encefaloceles. Un abordaje diagnóstico y terapéutico inapropiado podría generar desde simples recurrencias hasta fistulas e infecciones en el sistema nervioso central, que podrían contribuir a mayores complicaciones o incluso, poner en riesgo la vida de los pacientes.


Injuries to the naso-frontal region in children are a diagnostic challenge, associated with their rarity, their complexity also implies their potential communication with the central nervous system. Dermoid cysts, nasal gliomas, and encephaloceles are among the main entities in this region. An inappropriate diagnostic and therapeutic approach could generate from simple recurrences (as in our case), to fistulas and infections of the central nervous system that could contribute to greater complications or even put the lives of patients at risk.

ABSTRACT

RESUMEN Paciente de 32 años que acudió a consultas por epistaxis intermitente. A la exploración, se evidenció una masa proveniente del septum en fosa nasal izquierda no sospechosa, que a la biopsia demostró ser un angiofibroma. Se describe el abordaje terapéutico de un angiofibroma extranasofaríngeo septal y una revisión de la literatura.


ABSTRACT A 32-year-old patient attended our department for intermittent epistaxis. Upon examination, a non-suspicious mass coming from the septum was found in the left nostril, which at biopsy proved to be an angiofibroma. We describe the therapeutic approach of a septal extranasopharyngeal angiofibroma and a review of the literature.

ABSTRACT

RESUMEN El adenoma pleomorfo constituye la neoplasia benigna más frecuente de las glándulas salivales mayores, y puede también presentarse en otros sitios con mucha menor frecuencia como orofaringe, hipofaringe y nasofaringe. El adenoma pleomorfo intranasal es muy infrecuente y los casos descritos en la literatura local se refieren a tumores septales. Se presenta un caso clínico de una paciente que consulta por obstrucción nasal unilateral a derecha asociado a, epistaxis y epífora ipsilateral con estudio imagenológico y biopsia que sugiere adenoma pleomorfo de la pared lateral nasal. Se realiza revisión bibliográfica al respecto.


ABSTRACT The pleomorphic adenoma is the most frequent benign neoplasm of the major salivary glands. It can also present itself in other places with much less frequency such as oropharynx, hypopharynx and nasopharynx. The intranasal pleomorphic adenoma is very unusual and the cases described in the local literature address septal tumors. A clinical case is presented of a patient who consulted for unilateral right nasal obstruction associated with epistaxis and ipsilateral epiphora with imaging study and biopsy suggesting pleomorphic adenoma of the lateral nasal wall. A bibliographic review is made in this regard.

ABSTRACT

Resumen El estesioneuroblastoma (ENB), también conocido como neuroblastoma olfatorio, es una neoplasia maligna rara de la bóveda nasal que se cree que surge de las células receptoras neurosensoriales en el epitelio olfatorio. El ENB representa el 3% de todos los tumores nasales. Los tratamientos para ENB incluyen cirugía, radioterapia y/o quimioterapia, aunque a veces, es difícil lograr un tratamiento radical utilizando estas estrategias, ya que la mayoría de los pacientes se diagnostican en una etapa avanzada. Presentamos el caso de un varón de 46 años a quien se le diagnosticó ENB en el año 2016. Fue tratado inicialmente con resección endoscópica nasal, seguido de una craneotomía bifrontal. Posteriormente, recibió radioterapia adyuvante. Actualmente, su seguimiento a 3 años no muestra evidencia de metástasis locales, regionales o distantes, ni recurrencia.


Abstract Esthesioneuroblastoma (ENB), also known as olfactory neuroblastoma, is a rare malignant neoplasm of the nasal vault that is believed to arise from neurosensory receptor cells in the olfactory epithelium. ENB accounts for 3% of all nasal tumors. The treatments for ENB include surgery, radiotherapy and/or chemotherapy, though sometimes, it is difficult to achieve radical treatment using these strategies as most patients are diagnosed at a late stage. We present a case of a 46-year old male who had been diagnosed with ENB in 2016. He was initially treated with nasal endoscopic resection, followed by a bifrontal craniotomy. Afterwards, he received adjuvant radiotherapy. Currently, his 3-year follow up show no evidence of local, regional o distant metastasis, nor recurrence.

ABSTRACT

El Hamartoma Condromesenquimal Nasal (HCMN) es una neoplasia descrita por McDermott et al en 1998 en pacientes pediátricos, con pocos casos reportados en adultos. Este tumor está constituido por tejido condroide o cartilaginoso así como por tejidos mesenquimales. Es una lesión expansiva, localmente destructiva y en algunos casos está descrita la extensión intracraneal. El comportamiento es habitualmente benigno y el tratamiento consiste en la resección quirurgica. Se presenta un caso de un paciente masculino de 8 meses de edad, quien presentaba aumento de volumen en región periorbitaria derecha, con pseudoptosis palpebral, paresia del nervio oculomotor derecho y rinorrea hialina. Mediante la Tomografia Computarizada (TC) craneal y la Resonancia Magnética (RM) cerebral se observó lesión ocupante de espacio naso fronto etmoidal. El estudio histopatológico e inmunohistoquimico determinó la presencia de tumor mesenquimal fibrocartilaginoso osificante: Hamartoma Condromesenquimal. Se revisan las características y el tratamiento de este tumor poco frecuente(AU)


The Chondromesenchymal Nasal Hamartoma (CMNH) is a rare neoplasm described in 1998 by McDermott et al in the pediatric age, with few cases reported in adults. This tumor is composed by chondroid or cartilaginous tissue as well as mesenchymal tissues. It is an expansive lesion, locally destructive and in some cases intracranial extension is described. Its behavior is usually benign and its treatment consists of surgical resection. The authors present an 8-month-old male patient with increase volume in the right periorbital region, palpebral ptosis, paresis of the right oculomotor nerve and hyaline rhinorrhea. Computed Tomography (CT) and Cerebral Magnetic Resonance Imaging (MRI) were perfomed and revealed a nasofrontoethmoidal space occupying lesion; a histopathological and inmunohistochemical study resulted in osseous fibrocartilaginous mesenchymal tumor: chondromesenchymal hamartoma. We review the characteristics and treatment of this rare tumor(AU)

ABSTRACT

El angiomiolipoma de cavidad nasal es un tumor hamartomatoso extremadamente infrecuente compuesto por adipocitos maduros, espacios vasculares con escaso tejido elástico y la presencia de haces de células musculares lisas maduras. Se manifiesta principalmente por obstrucción nasal unilateral y epistaxis recurrente. Se presenta el caso de una paciente de 73 años con historia crónica de obstrucción nasal y epistaxis recurrente izquierda asociada a rinorrea y descarga posterior intermitente. La tomografía computarizada (TC) y resonancia nuclear magnética (RNM) demuestran una lesión vascular circunscrita en fosa nasal izquierda. La angiografía demostró irrigación exclusiva de la arteria esfenopalatina izquierda. Se realizó extirpación de la lesión por abordaje endonasal endoscópico previa embolización arterial. La revisión de la literatura mundial muestra que es el duodécimo caso de angiomiolipoma de cavidad nasal reportado.


Angiomyolipoma of nasal cavity is an extremely rare hamartoma tumor composed of mature adipocytes, vascular spaces with lack of elastic tissue, and the presence of bundles of mature smooth muscle cells. It manifests itself mainly by unilateral nasal obstruction and recurrent epistaxis. We present the case of a 73-years-old woman with chronic history of left-sided nasal obstruction and recurrent epistaxis associated with rhinorrhea and intermittent post nasal drip. Computed tomography and magnetic resonance imaging demonstrate a vascular lesion inside the left nasal cavity. Angiography showed irrigation exclusively by the left sphenopalatine artery Surgical excision was performed by endoscopic endonasal approach after arterial embolization. World literature review showed that this is the twelfth reported case of angiomyolipoma of the nasal cavity.

ABSTRACT

Introdução: O Schwannoma é uma neoplasia benigna com origem nas células de Schwann presentes na bainha de nervos autossômicos periféricos. Localiza-se cranial ou extracranial. Na cabeça e pescoço constitui 30 a 45% dos casos extracraniais, sendo que 4% deles estão localizados no nariz e seios paranasais. Relato do caso: Paciente feminina, 37 anos, realizou tomografia de crânio após queda para investigar trauma cranioencefálico. Esta identificou velamento de seios paranasais à esquerda. O achado motivou a investigação da hiposmia e obstrução nasal à esquerda de longa data. À rinoscopia anterior, observou-se lesão expansiva polipoide ocupando a fossa nasal, não permitindo a passagem do nasofibroscópio. Tomografia computadorizada evidenciou lesão ocupando totalmente a fossa nasal esquerda, velamento do seio maxilar e células etmoidais anteriores e posteriores à esquerda. Realizou-se exérese endoscópica da lesão, que tinha provável origem no recesso esfenoetmoidal. A biópsia transoperatória com congelação observou lesão inflamatória. A confirmação do diagnóstico de Schwannoma foi feita pelo anatomopatológico e imuno-histoquímica, que evidenciou alta reatividade à proteína S-100. Discussão: As lesões intranasais unilaterais apresentam inúmeras possibilidades diagnósticas. Os sintomas são inespecíficos e os exames de imagem pouco esclarecedores. Neste relato, a tomografia sugeriu pólipo de Killian ou papiloma invertido pela unilateralidade da lesão. Porém, as características histopatológicas e a imunorreatividade à proteína S-100 auxiliaram na confirmação diagnóstica. Conclusão: O Schwannoma intranasal faz parte do diagnóstico diferencial das lesões intranasais. O exame histopatológico e a imunohistoquímica são de extrema importância para confirmação diagnóstica frente à inespecificidade dos sintomas e achados radiológicos (AU)


Introduction: Schwannoma is a benign neoplasm originating in the Schwann cells present in the sheath of peripheral autosomal nerves. It is located cranially or extracranially. In the head and neck it comprises 30 to 45% of extracranial cases, 4% of which located in the nose and paranasal sinuses. Case report: A 37-year-old female patient underwent skull tomography after a fall to investigate cranioencephalic trauma. This identified veiling of paranasal sinuses on the left. The finding motivated the investigation of long-standing hyposmia and nasal obstruction on the left. At anterior rhinoscopy, an expansive polypoid lesion occupying the nasal fossa was observed, not allowing the nasofibroscope to pass. Computed tomography revealed a lesion totally occupying the left nasal fossa, maxillary sinus veil, and anterior and posterior ethmoid cells on the left. Endoscopic excision of the lesion that was likely to originate in the sphenoethmoidal recess was performed. Intraoperative biopsy with freezing showed an inflammatory lesion. Confirmation of the Schwannoma diagnosis was made by pathology and immunohistochemistry that showed high reactivity to S-100 protein. Discussion: Unilateral intranasal lesions present numerous diagnostic possibilities. The symptoms are nonspecific and imaging exams are not very elucidating. In this report, CT scan suggested a Killian polyp or inverted papilloma due to the unilaterality of the lesion. However, the histopathological characteristics and immunoreactivity to the S-100 protein aided in the diagnostic confirmation. Conclusion: Intranasal Schwannoma is part of the differential diagnosis of intranasal lesions. Histopathological examination and immunohistochemistry are extremely important for diagnostic confirmation in the face of the non-specificity of symptoms and radiological findings (AU)

ABSTRACT

Estesioneuroblastoma o también llamado neuroblastoma olfatorio es un tumor maligno infrecuente derivado del neuroepitelio olfatorio. La historia clínica de un paciente con un neuroblastoma olfatorio es muy inespecífica. Durante la última década, los métodos endoscópicos se han aplicado gradualmente para el tratamiento de tumores de la base del cráneo. El tratamiento puramente endoscópico endonasal del estesioneuroblastoma ha mostrado excelentes resultados de supervivencia con disminución de las complicaciones. Presentamos un paciente afectado por un neuroblastoma olfatorio tratado solo con cirugía endoscópica endonasal.


Esthesioneuroblastoma or olfactory neuroblastoma is an uncommon malignant tumor arising from the olfactory neuroepithelium. The clinical symptoms of a patient with olfactory neuroblastoma are very inespecific. During the past decade, endoscopic approaches have been gradually applied in treating skull base tumors. The purely endoscopic endonasal surgery for esthesioneuroblastoma showed successful survival results with remarkably decreased complications. We reported a patient who suffered olfactory neuroblastoma treated with only endoscopic endonasal surgery.

ABSTRACT

Los tumores neuroectodérmicos primitivos son tumores muy infrecuentes. Derivan de células embrionarias de la cresta neural, y comparten características con los sarcoma de Ewing extraóseos. Se presentan habitualmente en niños y adultos jóvenes, su ubicación más frecuente es en la región toracopulmonar, abdomen y extremidades. Son tumores que presentan una agresividad importante, lo que condiciona un pronóstico sombrío. La ubicación en fosas nasales-cavidades perinasales es anecdótica, existiendo el reporte de tan sólo un caso en la literatura mundial de ubicación en cavidad nasal.


Primitive neuroectodermal tumors are rare malignancies arising from embryonic neural crest cells. They share characteristics with extraosseous Ewing sarcoma. They usually occur in children and young adults and the most common location is the thoracopulmonary region, abdomen and extremities. These tumors have significant aggressiveness, which determines their poor prognosis. The location in nasal fossa-paranasal cavities is anecdotal. Until now only one previous case has been reported in the located in the nasal fossa.

ABSTRACT

Los plasmocitomas son tumores malignos caracterizados por proliferación anormal de células plasmáticas monoclonales. Éstos pueden originarse tanto en hueso como en tejidos blandos, denominados plasmocitomas óseos solitarios y plasmocitomas extra-medulares (PEM), respectivamente. Estos últimos representan menos del 1% de toda la patología maligna de cabeza y cuello, sin embargo, el reporte de estos casos resulta provechoso frente a la poca casuística al respecto. Presentamos el caso de plasmocitoma extramedular del septo nasal en un varón de 74 años con dificultad respiratoria nasal progresiva y frecuente epistaxis del lado izquierdo. A la especuloscopía nasal se observó en el vestíbulo una elevación tumoral de superficie lisa, grisácea, sésil. La biopsia mostró que era un plasmocitoma. Estudios posteriores descartaron la presencia de mieloma múltiple. Esto confirmó el diagnóstico de PEM. La masa fue completamente disecada, se indicó radioterapia y el paciente no tuvo adherencia al tratamiento. Sobre el mismo lecho al año siguiente reaparece lesión de similares características. Conclusión: Plasmocitoma extramedular del tabique nasal es una entidad rara, de una larga historia natural y que representa un desafío diagnóstico y terapéutico. Dependiendo de la resecabilidad de la lesión, la terapia combinada mediante cirugía y radioterapia es el tratamiento de elección.


Plasmacytomas are malignant tumors characterized by abnormal proliferation of monoclonal plasma cells. They may originate in bone and soft tissue , called solitary bone plasmacytoma and extramedullary plasmacytomas (EMP) respectively. The latter represents less than 1% of all malignant disease of the head and neck, however, the report of these cases it is useful to cope with the shallow casuistics thereon. We report a case of EMP of the nasal septum in a man of 74 years with progressive nasal breathing difficulties and frequent epistaxis on the left side. A nasal speculoscopy was observed in tumor lift lobby smooth, gray, sessile surface. The biopsy showed it was a plasmacytoma. Subsequent studies reject the presence of multiple myeloma. This confirmed the diagnosis of EMP. The mass was completely dissected, radiation therapy is indicated and the patient had no adherence. Upon the same place a similar injury returns. Conclusion: Septum extramedullary plasmacytoma is a rare entity of a long natural history and represents a diagnostic and therapeutic challenge. Depending on the resectability of the lesion, combination therapy with surgery and radiation therapy is the treatment of choice.

ABSTRACT

El hemangioma coroideo circunscrito es un tumor vascular hamartomatoso benigno de baja incidencia. Se presenta este caso debido a su evolución lenta y la pobre respuesta a tratamiento con terapia fotodinámica. El paciente, de sexo masculino, 49 años de edad, con disminución de la visión del ojo derecho de ocho meses de evolución y sin otra sintomatología asociada. Las exploraciones complementarias realizadas (retinografia, OCT, Ecografía y Angiografía flurosceínica) evidencian un tumor yuxtapapilar nasal que es diagnosticado como hemangioma circunscrito de coroides. Se decide tratarlo con terapia fotodinámica. En este caso, aunque el resultado en la ganancia visual no es el esperado, en los exámenes complementarios realizados se observa una discreta mejoría. La lenta evolución de este paciente responde, a criterio de los autores, a varios factores como la edad, el deterioro de la visión en el momento del diagnóstico, el número de aplicaciones de tratamiento con la TFD realizadas, el tiempo de evolución del tumor y el tamaño de la lesión(AU)


Circumscribed choroidal hemangioma is a benign hamartomatous vascular tumor of low incidence. This case is presented for its slow natural history and the poor response to treatment with photodynamic therapy. The 49-year-old male patient with right-eye visual reduction of eight month of evolution and without any other associated symptomatology. Complementary explorations carried out (retinography, OCT, sonogram, fluorescein angiography) evinces a juxtapapillary nasal tumor diagnosed as circumscribed choroidal hemangioma. The decision is to treat it with photodynamic therapy. In this case, despite the fact the visual gain outcome is not the desired, the complementary tests performed revealed a fair improvement. According to the authors, the slow evolution of this patient is due to several factors such as age, visual decay at the time of the diagnosis, the TFD number of applications, the tumor´s time of evolution and the lesion seize(AU)

ABSTRACT

In the early twentieth century, Argentina began legislating occupational safety. Law no.9.688 legislated accidents in the workplace (1915) and granted legal jurisdiction to work-related problems. The approval of this legislation was in dialogue with proposals being produced in other regions. The links established between local figures and colleagues elsewhere are useful for examining the circulation, reception and legitimation of knowledge on a regional scale. The objective of this article is to examine the transnational references in local discussions about occupational accidents in Peru and Chile during the first half of the twentieth century.


A partir del siglo XX, se inició en la Argentina la legislación protectora del trabajo. La ley n.9.688 legisló sobre accidentes de trabajo (1915) y otorgó jurisdicción legal a los problemas relativos al trabajo. La sanción de este corpus estuvo en diálogo con las propuestas que se producían en otras latitudes. Los vínculos que se establecieron entre los referentes locales y sus colegas son de utilidad para abordar el estudio de circulación, recepción y legitimación de los saberes dentro de una escala regional. Así pues, el objetivo de este trabajo es revisar las referencias transnacionales en las discusiones locales sobre los accidentes laborales en Perú y Chile durante la primera mitad del siglo XX.

ABSTRACT

INTRODUCTION: Extranodal NK/T-Cell lymphoma, nasal type (NKTLN) is a disease that mainly affects the nasal cavity and the paranasal sinuses. Early nasal symptoms are nonspecific, simulating sinus infection. With disease progression, necrosis of the nasal mucosa increases, hindering histological diagnosis. Thus, multiple biopsies may be necessary until definitive diagnosis. Most studies on NKTLN address the hematological and immunological aspects of the disease. OBJECTIVES: To present data from a Brazilian quaternary hospital, with emphasis on the clinical aspects of the disease, and to correlate the findings with the most recent literature data. METHODS: Case study of seven patient files. RESULTS: Patients were evaluated on their medical history, number of biopsies necessary, association with Epstein-Barr virus, treatment, and outcome. All patients had nonspecific nasal complaints and underwent at least three cycles of antibiotic therapy. The earlier a biopsy was performed, the fewer biopsies were required to diagnose the disease and start treatment. However, this fact did not translate into better prognosis. CONCLUSION: The otolaryngologist plays a fundamental role in the prognosis of NKTLN and can shorten time between symptom onset and treatment of the patient. .


INTRODUÇÃO: O linfoma extranodal de células NK/T tipo nasal (LNKTN) é uma doença que acomete preferencialmente a cavidade nasal e os seios paranasais. Os sintomas nasais iniciais são inespecíficos, mimetizando um quadro de infecção nasossinusal. Com a progressão da doença, aumenta a necrose da mucosa nasossinusal, dificultando o diagnóstico histológico e podendo ser necessárias múltiplas biópsias até o diagnóstico definitivo. A maioria dos estudos sobre o LNKTN aborda aspectos imunológicos e hematológicos da doença. OBJETIVO: Apresentar a casuística de um hospital quaternário brasileiro, destacando os aspectos clínicos dos pacientes e correlacionando aos achados mais recentes da literatura. MÉTODO: Estudo de casos de sete pacientes. RESULTADOS: Pacientes foram avaliados quanto a aspectos de sua história clínica, número de biópsias necessárias, associação ao EBV, tratamento e evolução. Todos iniciaram o quadro com queixas inespecíficas nasais e foram submetidos a pelo menos três ciclos de antibióticos. Quanto mais precocemente a biópsia foi realizada, menos biópsias foram necessárias para se obter o diagnóstico e iniciar o tratamento. Entretanto, esta situação não refletiu num melhor prognóstico dos pacientes. CONCLUSÃO: O otorrinolaringologista tem papel fundamental no prognóstico do LNKTN, podendo encurtar o tempo entre o início dos sintomas e o tratamento do paciente. .
