Orbital mucosa-associated lymphoid tissue (MALT) lymphoma as the initial presentation in patients with hepatitis C virus infection

ABSTRACT Hepatitis C virus infection may be implicated in 12.7% of ocular adnexal marginal zone lymphomas. We present the first case of an orbital-systemic mucosa-associated lymphoid tissue lymphoma that responded to hepatitis C virus medical treatment. A 62-year-old male with a right-sided orbital mass was diagnosed with stage IIA orbital marginal zone lymphoma in addition to hepatitis C virus infection based on clinical, imaging, laboratory, and histological examinations. The systemic and orbital responses were achieved 1 year after undergoing hepatitis C virus treatment with glecaprevir/pibrentasvir. The association between the hepatitis C virus infection and orbital-systemic mucosa-associated lymphoid tissue lymphoma is relevant. Accordingly, patients with orbital mucosa-associated lymphoid tissue lymphoma should be assessed for hepatitis C virus seroreactivity for therapeutic and prognostic purposes.

Biological identity of orbital cavernous venous malformations

ABSTRACT Vascular anomalies comprise a wide spectrum of clinical manifestations related to disturbances in the blood or lymph vessels. They correspond to mainly tumors (especially hemangiomas), characterized by high mitotic activity and proliferation of the vascular endothelium, and malformations, endowed with normal mitotic activity and no hypercellularity or changes in the rate of cell turnover. However, the classifications of these lesions go beyond this dichotomy and consist various systems adapted for and by different clinical subgroups. Thus, the classifications have not reached a consensus and have historically caused confusion regarding the nomenclatures and definitions. Cavernous venous malformations of the orbit, previously called cavernous hemangiomas, are the most common benign vascular orbital lesions in adults. Herein, we have compiled and discussed the various evidences, including clinical, radiological, morphological, and molecular evidence that indicate the non-neoplastic nature of these lesions.

Actualización en anomalías vasculares de la órbita en pediatría: diagnóstico por imágenes y tratamiento / Update on orbital vascular anomalies in pediatrics: imaging studies and management

Las anomalías vasculares de la órbita (AVO) son un grupo heterogéneo de patologías que pueden presentarse con frecuencia en el cono orbitario, la región periorbitaria o dentro de la órbita misma. Las AVO se dividen en tumores y malformaciones. Su presentación clínica más frecuente es el exoftalmos, asociado o no a alteración del eje visual. Además, pueden presentar complicaciones agudas, como hemorragia intralesional o celulitis entre las más frecuentes, y complicaciones crónicas, como ambliopía y afectación de la agudeza visual a largo plazo. La evolución de las técnicas de imágenes, el uso de nuevos fármacos y la utilización de innovadores procedimientos en radiología intervencionista han posibilitado obtener una mejora significativa en los procesos diagnósticos y terapéuticos de estos pacientes, permitiendo un diagnóstico y tratamiento preciso.

Orbital vascular anomalies (OVAs) are a heterogeneous group of disorders frequently found in the orbital cone, the periorbital region, or within the orbit itself. OVAs are divided into tumors and malformations. The most frequent clinical presentation is exophthalmos, associated or not with an alteration of the visual axis. They may also cause acute complications, being intralesional bleeding or cellulitis the most frequent, and chronic complications, such as amblyopia and long-term visual acuity impairment. The development of imaging techniques, the use of new drugs, and the implementation of innovative procedures in interventional radiology have resulted in a significant improvement in the diagnostic and therapeutic approaches to these patients, essential to an accurate diagnosis and management.

Mucormicosis orbitorrinocerebral: el manejo más allá de la cirugía. Informe de caso clínico y revisión de la literatura / Rhino-orbital-cerebral mucormycosis: management beyond surgery. Clinical case report and literature review

Introducción: se presenta el caso clínico de un paciente con mucormicosis orbitorrinocerebral y revisión de la literatura. Caso clínico: se trata de hombre de 45 años que consultó por síntomas nasosinusales manejado ambulatoriamente con múltiples antibióticos sin mejoría, por lo cual se realizó manejo quirúrgico con toma de muestras que revelaron hifas compatibles con mucormicosis. Cuando acudió a la institución presentaba extensión de la infección a todas las cavidades nasales y parte de la base del cráneo. En la búsqueda de la inmunosupresión, se encontró una diabetes de novo de difícil control. Discusión: la mucormicosis orbitorrinocerebral es una enfermedad altamente invasiva que requiere un manejo multidisciplinario, cirugías seriadas y extendidas, antimicóticos tópicos y sistémicos. El pronóstico mejora y la evolución puede ser favorable cuando se logra controlar la causa de la inmunosupresión, en este caso la diabetes. Conclusiones: es requisito fundamental realizar un tratamiento multidisciplinario en el abordaje de estos pacientes, tanto en la especialidad clínica como en la quirúrgica, psicosocial, nutricional y de rehabilitación.

Introduction: It is the clinical case of a patient with rhino-orbital-cerebral mucormycosis and the review of the literature. Clinical case: We present the case of a previously healthy young man who started with sinonasal symptoms and hyphae compatible with mucormycosis were found in the initial samples of outpatient care. When he came to the institution, the infection had spread to all the nasal cavities and part of the skull base. Discussion: Searching for baseline immunosuppression, only difficult-to-control diabetes and de novo diagnosis were found. It required multidisciplinary management, serial and extended surgeries, topical, venous and oral antifungals. The prognosis improved and the evolution became favorable when glycemic control was achieved. Conclusion: It is a fundamental requirement to carry out a multidisciplinary work for the approach to these patients, both in the clinical, surgical, psychosocial, nutritional and rehabilitation specialties.

Pérdida de agudeza visual progresiva en paciente con proptosis. Caso clínico y revisión de la literatura / Progressive visual impairment in a patient with proptosis. Case report and review of the literature.

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.

Bilateral metastases to the extraocular muscles from small cell lung carcinoma / Metástases bilaterais aos músculos extraoculares de um carcinoma de pequenas células do pulmão

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.

Giant frontal lipoma mimicking frontal mucocele / Lipoma frontal gigante mimetizando mucocele frontal

ABSTRACT Lipoma is a usually painless benign adipose tumor. Nevertheless, it can cause compression of adjacent structures, depending on its location. Mucoceles are benign cystic lesions in the frontal-ethmoidal region, caused by chronic obstruction of the paranasal sinus and consequent inflammatory processes. The increase of mucocele diameter caused by inflammation often results in bony degradation and reabsorption, increasing pressure on adjacent structures, including the orbit and the base of the skull, leading to possibly serious consequences. Here we report a case of lipoma mimicking a frontal mucocele, managed surgically at the Ophthalmological Hospital of Anapolis.

RESUMO O lipoma é um tumor do tecido adiposo de caráter benigno, usualmente indolor, porém que pode gerar compressão de estruturas adjacentes, dependendo da sua localização. A mucocele consiste em uma lesão cística de caráter benigno, na região fronto-etmoidal, devido à obstrução crônica dos óstios dos seios paranasais e consequente processo inflamatório. O aumento do diâmetro da mucocele por inflamação muitas vezes causa degradação e reabsorção ósseas, o que pode elevar a pressão em estruturas adjacentes como órbita e base de crânio, causando intercorrências possivelmente graves. Neste estudo relatamos um caso de lipoma simulando mucocele frontal, com propedêutica cirúrgica.

Undifferentiated pleomorphic sarcoma of the orbital region: a case report / Sarcoma pleomórfico indiferenciado da região orbitária: relato de caso

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.

Tumor primario quístico de la órbita: A propósito de un caso de hidatidosis infantil / Primary orbital cystic tumor: A case of hydatidosis in a child

RESUMEN Los tumores quísticos primarios de la órbita, causados por infestaciones parasitarias como el Equinococcus granulosus son raros. Al ser el Perú zona endémica para este parásito, presentamos el caso de una niña de 10 años de edad, proveniente de una zona rural de Huancavelica, con proptosis axial irreductible del globo ocular derecho, de curso progresivo, con pérdida de la agudeza visual e imágenes tomográficas de la órbita en relación a masa tumoral de apariencia quística. Los exámenes serológicos fueron negativos, la paciente fue sometida a resección quirúrgica con resultado histopatológico de membranas anhistas correspondientes a quiste hidatídico. Al año de seguimiento no se evidencia recurrencia local ni sistémica. En conclusión, ante una tumoración orbitaria quística en pacientes pediátricos, se debe de considerar como diagnóstico diferencial la hidatidosis orbitaria, sobre todo si proceden de zonas endémicas.

ABSTRACT Primary orbital cystic tumors caused by Echinococcus granulosus are rare. As this parasite is endemic in Peru, we report the case of a 10-year-old girl from a rural area of Huancavelica, who presented with progressive and irreducible axial proptosis of the right eye and loss of vision. Orbital tomographic images demonstrated a tumor mass with a cystic appearance. Serologic tests were negative. The patient underwent surgical resection, and histopathologic analysis revealed anhistic membranes, corresponding to hydatid cysts. During one year of follow-up, no evidence of local or systemic recurrence was observed. In conclusion, orbital hydatidosis should be considered in the differential diagnosis of a cystic orbital tumor in pediatric patients, especially if the patient is from an endemic area.

Metástasis intraorbitárias de cáncer de mama / Breast cancer orbital metastasis

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.

Oncocytoma of the lacrimal gland: a case report / Oncocitoma de glândula lacrimal: relato de caso

ABSTRACT Here we describe a rare case of a benign tumor in the lacrimal gland of a healthy 4-year-old girl. Mild proptosis was the only abnormality observed on clinical examination. Magnetic resonance imaging of the right orbit revealed an oval, solid, well-circumscribed, homogeneous mass extending from the lacrimal gland and measuring 2.5 × 2.3 × 1.7 cm without any evidence of invasion into adjacent bones. The lesion was surgically excised and histological analyses defined the diagnosis of oncocytoma of the lacrimal gland. Although rare, oncocytoma should be included in the differential diagnosis of lacrimal gland tumors.

Resumo Nós descrevemos um raro caso de tumor benigno na glândula lacrimal em uma criança sadia de 4 anos de idade. Clinicamente, a paciente apresentava apenas uma discreta proptose. A ressonância nuclear magnética (RNM) de órbita direita revelou a presença de uma massa oval, sólida, bem-circunscrita, homogênea, se extendendo a partir da glândula lacrimal, medindo 2,5 cm x 2,3 cm x 1,7 cm, sem nenhum sinal evidente de invasão a estrutura óssea adjacente. A lesão foi cirurgicamente removida e analizada histopatologicamente, sendo estabelecido o diagnóstico de oncocitoma de glândula lacrimal. Apesar de raro, o oncocitoma deve ser incluído no diagnóstico diferencial de qualquer tumor originado da glândula lacrimal.

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.

Extraconal cystic schwannoma mimicking an orbital dermoid cyst / Schwannoma cístico extraconal simulando um cisto dermóide orbitário

ABSTRACT To our knowledge, we report the first case of an extraconal orbital cystic schwannoma in Brazilian literature. The tumor grew slowly and progressively and was associated with minimal eccentric proptosis and diplopia. The radiologic study (orbital computed tomography) revealed a rounded, encapsulated, and extraconal cystic mass in the superior medial region of the right orbit in the supraorbital and supratrochlear nerve topography. An anterior orbitotomy with full excision of the tumor was performed, and the histopathology examination revealed that the tumor was a schwannoma. After the surgery, the patient experienced total remission of his symptoms.

RESUMO Os autores relatam o primeiro caso de schwannoma orbitário extraconal cístico relatado na literatura brasileira. O tumor apresentou aparecimento lento e progressivo, associado a proptose excêntrica e diplopia leves. O exame de imagem (tomografia computadorizada de órbita) revelou uma lesão nodular, arredondada, capsulada, extracônica, cística, na região súpero-medial de órbita direita, na topografia do nervo supraorbitário e supra-troclear. O paciente foi submetido à orbitotomia por via anterior, com exérese integral da tumoração. O exame histopatológico revelou o diagnóstico de schwannoma. Após a cirurgia, o paciente teve regressão total dos sintomas.

Hallazgos tomográficos en pacientes con tumores orbitarios / Tomographic Findings in Patients with Orbital Tumors in Holguin

Introducción: los tumores de la órbita son infrecuentes, pueden originarse en las paredes o en el contenido de la órbita o desde las cavidades próximas. Las técnicas de imagen y sobre todo la tomografía axial computarizada, son una herramienta indispensable en el conocimiento de las enfermedades oftalmológicas. Objetivo: describir los hallazgos tomográficos en pacientes con tumores orbitarios. Métodos: se realizó un estudio de serie de casos a pacientes con tumores de órbita procedentes de la Consulta Provincial de Oftalmología del Hospital Vladimir Ilich Lenin en el período comprendido de enero 2009-enero 2010 en estrecha relación con los Servicios de Imagenología y Anatomía Patológica. El Universo quedó constituido por 17 pacientes, previo consentimiento informado, con diagnóstico clínico de tumores de órbita atendidos en la Consulta de Oftalmología y que no reportaron alergia al contraste. Resultados: existió un predominio del grupo de edad de 51 a 60 años con cinco casos para el 29,4 %. Prevaleció como signo al examen físico, el exoftalmos y la proptosis constituyó el hallazgo tomográfico más frecuente (76,4 %). La localización extraconal de los procesos orbitarios fue la predominante (9 pacientes con el 52,9 %), así como, las lesiones heterogéneas (14 casos para el 82,3 %). Conclusiones: La tomografía axial computarizada constituyó el método imagenológico de elección en todos los pacientes con sospecha clínica de tumores orbitarios pues permitió identificar la localización, presencia de proptosis y estructura de las lesiones tumorales.

Introduction: orbital tumors are rare and can arise in the walls or in the content of the orbit or from the closest cavities. Imaging techniques and especially computed tomography is an indispensable tool in understanding ophthalmic diseases. Objective: describe the tomography findings in patients with orbital tumors. Methods: a descriptive and prospective study was carried out comprising a series of cases of patients from the provincial doctor´s ophthalmology office at Vladimir Ilich Lenin Hospital, who presented orbit tumor during the period from January 2009 to January 2010, in conjunction with the radiology and pathological anatomy services. The sample was made up of 17 patients seen at the ophthalmology consultation, all of who had been diagnosed with orbital tumors and who were not allergic to the contrast. Results: the age group between 51 to 60 years old predominated over the rest of the patients (5 cases to 29.4 %). Exophthalmus was the prevailing sign upon physical examination and protosis was the most frequent tomography finding (13 patients to 76.4 %). The extraconal location of the orbital processes prevailed (9 patients to 52.9 %), as well as heterogeneous lesions that (14 cases to 82.3 %). Conclusion: CT Scan (computed Tomography) constitutes the imaging method of choice in all patients who are clinically suspected to present orbital tumors because it allows to identify the location, proptosis presence and the structure of the tumoral lesions.

The authors describe two cases of patients with uncommon primary orbital tumors whose diagnosis was obtained by means of computed tomography-guided core needle biopsy, with emphasis on the technical aspects of the procedure.

Rabdomiosarcoma orbitario. Presentación de un caso / Orbital Rhabdomyosarcoma. A Case Report

El rabdomiosarcoma es un tumor maligno originado por células musculares esqueléticas normales y como dichas células están presentes en casi todo el organismo, este tumor puede tener cualquier localización, a pesar de lo cual no es muy frecuente. Se presenta el caso de un paciente de seis años de edad, de Kuito Bie, Angola, que fue atendido por médicos cubanos de misión en ese país, y que acudió a su consulta por aumento de volumen de una masa tumoral que protuía por la cavidad orbitaria. Su padre refería antecedentes de traumatismo ocular por el cual había sido ingresado y llevado tratamiento, pero evolucionó tórpidamente y se le había realizado evisceración del ojo derecho. Se realizaron estudios del tumor y se concluyó como un rabdomiosarcoma orbitario. Por lo poco común de la entidad y la importancia del diagnóstico y tratamiento oportuno, se decidió la presentación del caso.

Rhabdomyosarcoma is a malignant tumor arising from normal skeletal muscle cells. Since these cells are found in almost every part of the body, this type of tumor may develop in any site, though it is not very common. The case of a six-year-old Angolan patient treated by Cuban collaborators serving in this country is presented. The patient sought medical attention due to inflammation and pain in the right eye. His relative mentioned a history of ocular trauma, resulting in the patient’s admission to receive treatment a week before. On eye examination, a whitish spot through the pupil and slight proptosis were found. The patient had an unsatisfactory recovery; consequently an evisceration of the right eye was performed. Three months later, he developed an enlarging mass protruding in the orbital cavity. Several studies were conducted and an orbital rhabdomyosarcoma was diagnosed.
