ABSTRACT

Introducción: Los quistes de retención mucoso de los senos paranasales son un hallazgo imagenológico incidental muy frecuente. Usualmente comprometen el seno maxilar. Metodología: Se realizó una amplia búsqueda de la literatura, sobre quistes de retención mucoso nasosinusales, en enero de 2021 en múltiples bases de datos. Se seleccionaron 21 artículos sobre el tema para la realización de la revisión. Discusión: En la mayoría de los casos el tratamiento de los quistes de retención mucoso nasosinusales debe ser expectante debido a su tendencia a la involución y curso asintomático. Sin embargo, en la práctica clínica se observa con frecuencia un manejo quirúrgico sin una indicación clara. Conclusiones: Las indicaciones quirúrgicas de los quistes de retención mucoso son: obstrucción del ostium del seno paranasal, compromiso del complejo ostiomeatal o compromiso del nervio infraorbitario con síntomas secundarios. Es importante que el cirujano reconozca la naturaleza y comportamiento de esta patología para evitar procedimientos quirúrgicos innecesarios.


Introduction: Mucous retention cysts of the paranasal sinuses are a very common incidental imaging finding. They usually involve the maxillary sinus. Methodology: An extensive literature search on nasosinusal mucosal retention cysts was conducted in January 2021 through multiple databases. 21 articles on the subject were included as evidence for this paper. Discussion: In most cases, treatment should be expectant due to its tendency to involution and asymptomatic course. However, in clinical practice, surgical management is frequently observed without a clear indication. Conclusions: Surgical indications for mucosal retention cysts are: obstruction of the sinus ostium, involvement of the ostiomeatal complex, or involvement of the infraorbital nerve with secondary symptoms. It is important for the surgeon to recognize the nature and behavior of this pathology in order to avoid unnecessary surgical procedures.

ABSTRACT

Introducción: a raíz del siguiente reporte de caso clínico se pretende repensar el diagnóstico diferencial de los tumores orbitales y revisar la literatura existente al respecto. Caso: paciente de 54 años, fumadora, acude a nuestro centro por una pérdida de agudeza visual progresiva de dos años de evolución en el ojo derecho, que se acompañaba de proptosis. Las pruebas de imagen basadas en resonancia magnética y tomografía por emisión de positrones ­ tomografía computarizada (PET-TC) realizadas describían una lesión intraconal derecha de morfología indefinida, que rodeaba el nervio óptico. El estudio inmunohistoquímico y molecular anatomopatológico confirmó la sospecha de síndrome linfoproliferativo extranodal de bajo grado. Discusión: el manejo endoscópico de estas lesiones puede resultar en una menor comorbilidad en comparación con el abordaje externo tradicional. El papel de la cirugía radica en la obtención de una muestra de la lesión que permita un correcto diagnóstico. Conclusiones: el abordaje multidisciplinar con oftalmólogos, hematólogos y expertos en radioterapia permite obtener buenos resultados quirúrgicos y clínicos en la inmensa mayoría de casos.


Introduction: as result of the following clinical case report, we intend to review the differential diagnosis of orbital tumors and review the existing literature in this regard. Case report: a 54-year-old smoking patient, consulted to our department due to a progressive visual impairment over the last two years in her right eye. She presented proptosis in her clinical examination. Imaging studies based on MRI and PET-CT described a right intraconal lesion with an undefined morphology surrounding the optic nerve. Orbital tumors differential diagnosis is delicate. Nevertheless, Non-Hodgkin lymphomas followed by metastasis are the two most common found in this location. The immunohistochemistry and molecular studies, confirmed the suspected diagnosis of extranodal low-grade lymphoproliferative syndrome. Discussion: endoscopic management of these lesions may result in a lower comorbidity compared to traditional external approaches. Role of surgery lays in obtainment of a quality sample which allows a proper diagnosis. Conclusions: multidisciplinary approach with ophthalmologists, hematologists and radiotherapy experts enhance good surgical and clinical results in the vast majority of cases.

ABSTRACT

ABSTRACT Bilateral orbital metastases restricted to the extraocular muscles (EOMs) are exceedingly rare. We report a case of bilateral extraocular muscle metastases from a small cell lung carcinoma and provide a review of the relevant literature. A 56-year-old smoker presented with proptosis, motility changes, and a relative afferent pupillary defect of the left eye, with a previous history of a small cell lung carcinoma. An orbital computerized tomography scan revealed a mass restricted to the left medial rectus. An incisional biopsy confirmed metastasis. Visual acuity of the left eye decreased rapidly, and right globe proptosis became evident. Orbital magnetic resonance imaging at two months follow-up showed marked left orbital mass enlargement and a new right lateral rectus mass. The patient was maintained on palliative care and died from metastatic disease-related complications.


RESUMO As metástases orbitárias bilaterais restritas aos mús­culos extraoculares são extremamente raras. Os autores apresentam um caso de metástases bilaterais, localizadas aos musculares extraoculares com base num carcinoma de pequenas células do pulmão e revisão da literatura relevante. Um homem, fumador, de 56 anos recorreu ao serviço de urgência por proptose, alterações de motilidade ocular extrínseca e um defeito pupilar aferente relativo do olho esquerdo, com história pessoal de carcinoma de pequenas células do pulmão. A tomografia computadorizada orbitária revelou uma massa restrita ao reto medial esquerdo. Uma biópsia incisional confirmou o diagnóstico de metástase. A acuidade visual do olho esquerdo diminuiu rapidamente e surgiu uma proptose do globo ocular direito. A ressonância magnética orbitária aos dois meses de seguimento revelou um aumento da massa orbitária esquerda e uma nova massa no reto lateral direito. O paciente foi mantido em cuidados paliativos e faleceu devido a complicações relacionadas com doença metastática.

ABSTRACT

Abstract Introduction: Endoscopic orbital surgery is a nascent field and new tools are required to assist with surgical planning and to ascertain the limits of the tumor resectability. Objective: We purpose to utilize three-dimensional radiographic reconstruction to define the theoretical lateral limit of endoscopic resectability of primary orbital tumors and to apply these boundary conditions to surgical cases. Methods: A three-dimensional orbital model was rendered in 4 representative patients presenting with primary orbital tumors using OsiriX open source imaging software. A 2-Dimensional plane was propagated between the contralateral nare and a line tangential to the long axis of the optic nerve reflecting the trajectory of a trans-septal approach. Any tumor volume falling medial to the optic nerve and/or within the space inferior to this plane of resectability was considered theoretically resectable regardless of how far it extended lateral to the optic nerve as nerve retraction would be unnecessary. Actual tumor volumes were then superimposed over this plan and correlated with surgical outcomes. Results: Among the 4 lesions analyzed, two were fully medial to the optic nerve, one extended lateral to the optic nerve but remained inferior to the plane of resectability, and one extended both lateral to the optic nerve and superior to the plane of resectability. As predicted by the three-dimensional modeling, a complete resection was achieved in all lesions except one that transgressed the plane of resectability. No new diplopia or vision loss was observed in any patient. Conclusion: Three-dimensional reconstruction enhances preoperative planning for endoscopic orbital surgery. Tumors that extend lateral to the optic nerve may still be candidates for a purely endoscopic resection as long as they do not extend above the plane of resectability described herein.


Resumo Introdução: A cirurgia orbital endoscópica é um campo emergente e são necessárias novas ferramentas para auxiliar no planejamento cirúrgico e determinar os limites da ressecabilidade tumoral. Objetivo: Usar a reconstrução radiográfica tridimensional para definir o limite lateral teórico de ressecabilidade endoscópica de tumores orbitais primários e aplicar essas condições de limites a casos cirúrgicos. Método: Um modelo orbital tridimensional foi aplicado a quatro pacientes representativos com tumores orbitais primários utilizando o software de imagem de fonte aberta OsiriX. Um plano bidimensional foi propagado entre a narina contralateral e uma linha tangencial ao eixo longo do nervo óptico que reflete a trajetória de uma abordagem transeptal. Qualquer volume de tumor situado medialmente ao nervo óptico e/ou dentro do espaço inferior a esse plano de ressecabilidade foi teoricamente considerado ressecável, independentemente de quão longe ele se estendia até o nervo óptico, pois a retração do nervo seria desnecessária. Os volumes reais do tumor foram então sobrepostos sobre esse plano e correlacionados com os resultados cirúrgicos. Resultados: Entre as quatro lesões analisadas, duas eram totalmente mediais ao nervo óptico, uma se estendia lateralmente ao nervo óptico, mas permaneceu inferior ao plano de ressecabilidade, e uma se estendia lateralmente ao nervo óptico e superior ao plano de ressecabilidade. Conforme previsto pelo modelo tridimensional, uma ressecção completa foi obtida em todas as lesões, exceto uma, que transgrediu o plano de ressecabilidade. Nenhuma nova diplopia ou perda de visão foi observada em qualquer paciente. Conclusão: A reconstrução tridimensional melhora o planejamento pré-operatório para a cirurgia orbital endoscópica. Os tumores que se estendem lateralmente ao nervo óptico podem ainda ser candidatos à ressecção puramente endoscópica, desde que não se estendam além do plano de ressecabilidade aqui descrito.

ABSTRACT

ABSTRACT Undifferentiated pleomorphic sarcoma (UPS) is an extremely rare tumor that occurs in the head and neck region. Here, we report a unique case of a primary undifferentiated pleomorphic sarcoma in the orbital region. A 35-year-old woman presented with a progressive proptosis and periocular edema for 1 year. She had no previous history of surgery, skin malignancy, or radiation. Imaging tests showed an extraconal mass, not involving the muscles. The tumor was surgically removed and adjuvant radiotherapy was required after histological examination, which showed an undifferentiated pleomorphic sarcoma of the orbit. There was no recurrence after 1 year of follow-up. Though rare, undifferentiated pleomorphic sarcoma should be included in the differential diagnoses of orbital tumors.


RESUMO O sarcoma pleomórfico indiferenciado (SPI) é um tumor extremamente raro na região da cabeça e pescoço. Relatamos um caso de um sarcoma pleomórfico indiferenciado primário na região orbital. Uma mulher de 35 anos apresentou proptose progressiva e edema periocular há um ano. Ela não tinha histórico prévio de cirurgia, malignidade da pele ou radiação. Exames de imagem mostraram uma massa extraconal, poupando os músculos. O tumor foi removido cirurgicamente e foi necessária radioterapia adjuvante após o resultado histopatológico. O exame histológico demonstrou um sarcoma pleomórfico indiferenciado da órbita. Não houve recidiva após 1 ano de seguimento. Apesar de raro, o sarcoma pleomórfico indiferenciado deve ser incluído no diagnostico diferencial de qualquer tumor originado na órbita.

ABSTRACT

Resumo Mieloma múltiplo (MM) é uma neoplasia que cursa com a proliferação desordenada de clones de plasmócitos, produzindo imunoglobulina monoclonal e normalmente se apresenta como lesões osteolíticas. Em alguns casos, porém, esta doença apresenta-se como massas, chamadas de plasmocitomas. O acometimento ocular e orbitário é incomum nesta patologia. Neste trabalho, descrevemos o caso de uma paciente de 63 anos com diagnóstico prévio de MM que evoluiu com um plasmocitoma intraconal em olho direito, bem como uma massa vascularizada câmara anterior proveniente de infiltração uveal. Essas lesões foram correlacionadas MM e culminaram com a perda visual no olho acometido. Não foi encontrado na literatura relatos de plasmocitoma intraconal.


Abstract Multiple myeloma (MM) leads to disorderly proliferation of plasma cells clones, producing monoclonal immunoglobulin and commonly presents osteolytic lesions. In some cases, however, masses called plasmocytomas are found. Ocular and orbital involvement is unusual in this pathology. In this paper, we describe a case of a 63 year-old patient with previous diagnostic of MM that evolved an intraconal plasmocytoma in the right eye, as well as a vascularized mass in the anterior chamber from uveal infiltration. These lesions were correlated to MM e lead to visual loss in the affected eye. Reports of intraconal plasmocytoma have not been found in literature.

ABSTRACT

Orbital metastasis is a rare event, and metastatic disease affecting the extraocular muscles is an even less frequent complication of solid tumors. Herein, we report an unusual case of ptosis as the initial presentation of an invasive breast cancer. A 68-year-old woman presented with III and VI partial nerve paresis, secondary to a compressive retrobulbar mass. Magnetic resonance imaging revealed an infiltrative lesion involving the extraocular muscles. Tissue biopsy yielded a result compatible with metastasis to the orbit, with immunohistochemistry analysis suggesting breast as the primary organ. Mammography identified an area of architectural distortion; stereotactic wire-guided biopsy confirmed the result of the previous orbital biopsy. A positron emission tomography scan demonstrated disseminated disease. Palliative chemotherapy with bone-modulating agents and subsequent hormonal therapy was proposed. Unfortunately, the patient did not respond to therapy and died 38 months after diagnosis.

ABSTRACT

Objetivo: Describir un caso raro de una paciente previamente diagnosticada con cáncer de mama que evolucionó después de algunos años con metástasis intraorbitaria. Métodos: Relato del caso y revisión de literatura. Resultados: La correlación del diagnóstico previo de neoplasia de mama y la presencia de múltiples lesiones en la órbita y regiones adjacentes ha permitido concluir que la paciente presentaba enfermedad metastásica. Las metástasis se presentan como manifestaciones cada vez más frecuentes en enfermos oncológicos. La órbita y estruturas próximas constituyen topografías poco usuales de diseminaciónde células neoplásicas y manifestaciones iniciales pueden mimetizar otras condiciones, retrasando el diagnóstico. Como se trataban de pequeñas lesiones, se ha optado por radioterapia como tratamiento único. Después del término la paciente evolucionó con regresión de sintomatología. Conclusiones: Aunque infrecuentes, manifestaciones oculares pueden ocurrir en enfermos oncológicos y la investigación de enfermedad metastático de la órbita es esencial para el seguimiento adecuado.


Objective: Description a rare case of a patient with previous diagnosis of breast cancer that evolved years after with orbital metastasis. Method: Case report and literature review. Results: The relation between the previous diagnosis of breast cancer and the presence of multiple orbital and adjacent lesions allowed concluding that the patient presented metastatic disease. Metastasis presented as a common manifestation in oncological patients. Orbit and neighboring structures constitute unusualsite of neoplastic cells dissemination and initial manifestations could mimic other conditions, which can slow diagnosis. As they were small lesions that are close to noble structures, it was opted by performing exclusive radiotherapy. After the end of treatment, the patient referred improvement of her symptoms. Conclusions: Although unusual, ocular manifestations could occur in oncological patients and orbit metastatic disease investigation is essential to the proper follow.

ABSTRACT

ABSTRACT Solitary fibrous tumor (SFT) is a rare mesenchymal spindle-cell neoplasm commonly found in the pleura; it is rare in the orbit and extremely rare in the lacrimal gland. We herein report a case of SFT of the lacrimal gland that mimicked a pleo morphic adenoma. We discuss the clinical, radiological, histopathological, and immunohistochemical findings that provided insight and rationale to accurately diagnose this case.


RESUMO Os autores relatam um caso de tumor fibroso solitário (TFS) de glândula lacrimal simulando um adenoma pleomórfico. O TFS é um raro tumor mesenquimal de células fusiformes, comumente encontrado na membrana pleural, raramente en contrado na órbita e extremamente raro na glândula lacrimal. Os autores discutem os achados clínicos, radiológicos, histológicos e imunohistoquímicos que são a chave para o correto diagnóstico desta rara entidade.

ABSTRACT

El carcinoma escamoso primario de órbita es una entidad poco frecuente. Hay escasa literatura publicada al respecto. Presentamos un caso de carcinoma escamoso primario de los tejidos blandos de la órbita. La resección quirúrgica ofrecía el mejor tratamiento para esta paciente. Se realizó un abordaje cráneo-facial y se logró la resección completa de la lesión. La paciente recibió radioterapia adyuvante debido a la proximidad de la lesión a los márgenes quirúrgicos. El tratamiento quirúrgico es factible y debe ser considerado como parte del arsenal del cirujano. Sin embargo, las decisiones terapéuticas deben tomarse teniendo en cuenta las particularidades de cada caso.


Primary orbital squamous cell carcinoma is a rare entity. There is little published literature. We report a case of primary squamous cell carcinoma of the orbital soft tissues. Surgical resection offered the best treatment for the patient. Complete resection of the lesion was achieved. The patient received adjuvant radiotherapy due to the proximity of the lesion to the surgical margins. Surgical treatment is feasible and should be considered as part of the surgeon´s arsenal. However, therapeutic decisions must be made on a case-by-case basis.

ABSTRACT

Orbital metastases are rare and predominantly unilateral occurrences. Bilateral metastases affecting the extraocular muscles are extremely rare. A few case reports of bilateral metastases to extraocular muscles described binocular diplopia with conspicuous bilateral external ophthalmoplegia as an initial symptom. We report a case in which unilateral ptosis was an initial symptom and bilateral incomplete ophthalmoplegia was found on initial neurologic examination in invasive ductal carcinoma of the breast. The patient had hormone receptor-positive breast cancer, and so was treated by hormonal therapies and closely monitored. The presence of a secondary orbital lesion presents many difficulties of differential diagnosis and treatment. A thorough neurologic examination to detect ocular manifestations is most important for localization and broad differential diagnosis including mechanical orbital metastatic lesion.

ABSTRACT

RESUMO Objetivo: Descrever os casos de exenteração orbitária de um hospital terciário brasileiro. Métodos: Estudo retrospectivo, envolvendo pacientes submetidos à exenteração orbitária no Hospital das Clínicas da Faculdade de Medicina de Botucatu, entre os anos de 1993 a 2016. As cirurgias foram realizadas sob anestesia geral, por equipe multidisciplinar composta por oftalmologistas, otorrinolaringologistas e cirurgiões de cabeça e pescoço. Resultados: Foram estudados 14 casos de exenteração orbitária, com média de idade de 63,36 ± 13,18 anos e nove homens (64,3%). Todas cirurgias foram realizadas para tratamento de tumores malignos, sendo mais frequente o carcinoma espinocelular (7 casos - 50,0%). Os sítios primários mais frequentes foram as pálpebras (50,0%), seguida pela conjuntiva (28,6%). A maioria das cirurgias foram do tipo exenteração estendida (57,1%), com cicatrização por granulação espontânea (64,3%). A sobrevida em 1 ano foi de 78,6% e em 5 anos de 71,4%. Conclusão: O carcinoma espinocelular foi a principal causa de indicação de exenteração orbitaria, sendo as pálpebras o sítio primário mais frequente. O procedimento mais realizado foi a exenteração estendida, com a grande maioria alcançando margens livres.


ABSTRACT Objective: To describe causes of orbital exenteration in a Brazilian tertiary hospital. Methods: A retrospective study was done, involving patients submitted to orbital exenteration at the Clinical Hospital of Botucatu Medical School, between the years of 1993 to 2016. The surgeries have been performed under general anesthesia, by a multidisciplinary team, composed by ophthalmologists, otolaryngologists and head and neck surgeons. Results: Fourteen cases of orbital exenteration occurred in the period of the study, with a mean age of 63.36 ± 13.18 years and nine were men (64.3%). All exenteration were due to malignant tumors, being more frequent the squamous cell carcinoma (7 cases - 50.0%). The most common primary sites were the eyelids (50.0%) followed by the conjunctiva (28.6%). The majority of the surgeries was extended exenteration type (57.1%) and most of the reconstructions was made by spontaneous granulation (64.3%). The survivor rate in 1 year was 78,6% and in 5 years was 71.4%. Conclusion: The main cause of orbital exenteration was squamous cell carcinoma and the most frequent primary site was the eyelids. Extended exenteration was necessary for the majority of cases, most of them with free margins.

ABSTRACT

Retrobulbar tumors may arise from any orbital tissue. Some are primary and others may extend from adjacent structures or derived from metastases. Multilobular osteochondrosarcomas are regarded as slowly growing and potentially malignant neoplasms in dogs. This tumor is of rare occurrence on retrobulbar region. This paper aims to report a rare case of female dog, Shih Tzu, spayed, five-year-old, that was referred to the Hospital of Veterinary Medicine, Federal University of Bahia, Brazil, with an increased volume in the orbital space, after enucleation for exophthalmia of unknown etiology. This animal was evaluated clinic and the diagnosis image (radiography and computed tomography) demonstrated a large formation of bone predominantly in the region of the right orbit and zygomatic arch, with invasion and destruction of adjacent bones. Due to her poor quality of life, the dog was submitted to euthanasia and after necropsy. On gross examination, an encapsulated nodular mass with an irregular surface, measuring 5.6 x 4.6 x 3.9 cm, was located in the right lateral skull, occupying the orbit with displacement of the zygomatic arch. The tumor was identified by histopathology as a malignant mesenchymal neoplasm, multilobular osteochondrosarcoma. Thus, differential diagnoses for exophthalmos should include cancers, including the multilobular osteocondrossarcoma.


Tumores retrobulbares podem originar-se de qualquer tecido orbital. Alguns são primários e outros podem estender-se a partir de estruturas adjacentes ou derivados de metástases. O osteocondrosarcoma multilobular é um tumor considerado de crescimento lento, potencialmente maligno e sua ocorrência é considerada rara em região orbital. Este trabalho objetiva descrever um caso de uma cadela, Shih Tzu, castrada, com cinco anos, atendida no Hospital de Medicina Veterinária da Universidade Federal da Bahia, Brasil, com apresentação de aumento de volume no espaço orbital, após enucleação devido a exoftalmia de etiologia desconhecida. O animal foi avaliado clinicamente e por exames de imagem (radiografia e tomografia computadorizada), os quais demonstraram uma grande formação óssea predominantemente na região da órbita direita e arco zigomático, com invasão e destruição dos ossos adjacentes. Devido às más condições de sobrevida apresentada pelo animal, foi indicado o procedimento de eutanásia e por fim, submetido à necropsia. No exame macroscópico, uma massa nodular encapsulada de superfície irregular, medindo 5,6 x 4,6 x 3,9 centímetros, foi localizada no crânio lateral direito, ocupando a órbita com deslocamento do arco zigomático. O tumor foi identificado por exame histopatológico como neoplasia mesenquimal maligna, osteocondrossarcoma multilobular. Desta forma, diagnósticos diferenciais para exoftalmia devem incluir neoplasias, dentre elas o osteocondrossarcoma multilobular.

ABSTRACT

El linfangioma es un tumor benigno raro y predominante en la infancia, debido a su crecimiento puede comprometer al órgano donde se desarrolla, se han propuesto varias opciones de trata-miento, sin embargo, la cirugía continúa siendo la primera opción. La neuronavegación permite realizar exéresis con gran precisión y de utilidad en cirugía ocular, por lo que disminuye el riesgo de secuelas después de una exéresis de linfangioma orbitario.


Lymphangioma is a benign tumor predominantly in childhood, due to growth that can compromise the organ where it grows. Several treatment options, have been proposed however,surgery remains the first choice. Neuronavigation allows successful excision and use in eye surgery,which decreases the risk of sequels following excision of orbital lymphangioma.
