Introducción. El carcinoma epidermoide cutáneo (CEC) es la segunda neoplasia cutánea más frecuente después del carcinoma basocelular. La incidencia del CEC ha aumentado de forma considerable durante los últimos 20 años y predicen un incremento en la próxima década. La mayoría de los CEC están localizados y se resuelven habitualmente mediante la extirpación quirúrgica u otros procedimientos locales. El uso del músculo temporal es una alternativa quirúrgica para corregir el defecto periorbitario tras la extirpación del CEC. Objetivo. Evaluar el resultado de la cobertura del músculo temporal en la corrección del defecto periorbitario. Material y métodos. Se presenta un caso quirúrgico de un paciente masculino, 62 años, que presenta una gran lesión tumoral que compromete el globo ocular, región orbitaria y periorbitaria izquierda, acompañado de dolor, anemia, astenia y pérdida ponderal de aproximadamente 20 libras. Con una evolución de 6 años. Conclusión. El uso del músculo temporal es una alternativa eficaz en la reconstrucción de lesiones craneofaciales, que ha sido utilizado por más de 100 años.

Introduction. Skin epidermoid carcinoma (SEC) is the second most common skin neoplasm after basal cell carcinoma. The incidence of SEC has increased considerably over the past 20 years and predicts an increase over the next decade. Most SECs are located and usually resolved by surgical removal or other local procedures. The use of the temporal muscle is a surgical alternative to correct the peri-orbital defect after removal of the SEC. Objective. To evaluate the result of temporal muscle coverage in the correction of the peri-orbital defect. Material and methods. There is a surgical case of a male patient, 62 years old who has a large tumor injury that compromises the eyeball, orbital region and left periorbital. Accompanied by pain, anemia, asthenia, and weight loss approximately 20 pounds. With an evolution of 6 years. Conclusion. The use of the temporalis muscle is an effective alternative in the reconstruction of craniofacial lesions that has been used for more than 100 years

Introduction: The ocular neoplasm can affect the eye, annexes and orbit. The effective treatment depends on an early, presumptive and accurate diagnosis. Objective: To characterize patients with eye cancer according to variables of interest. Method: An observational, descriptive and retrospective study of 58 patients with eye malignancy confirmed by means of biopsy was carried out. They were assisted in the Ocular Plastic Surgery Service of the Ophthalmologic Center at Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from October, 2015 to the same period in 2020. The mean was used for the quantitative variables. Results: In the series the mean age was of 62.49 years; there was a prevalence of the male sex (51.7 %) and the mixed race color of the skin (53.4 %). The most frequent localization of the tumoral lesions in the annexes was in the lids (53.4 %) and the conjunctive (41.4 %). The predominant histologic types were palpebral basal cell carcinoma (44.8 %) and squamous cell carcinoma of the conjunctive (41.4 %). The estadification of the tumor was established: T1 en 47 patients, T2 and T3 in 4, as well as T4 in 3. Conclusions: The control of the eye cancer is very important, because it allows to trace strategies for the early diagnosis and the appropriate treatment of patients.

Treatment and prognosis of primary ocular adnexal extranodal marginal zone mucosa-associated lymphoid tissue lymphoma: a report from a single center / 中华血液学杂志

Objective: This study aimed to see how different initial treatment regimens affected the long-term prognosis of patients with extranodal marginal zone mucosa-associated lymphoid tissue lymphoma confining to the ocular adnexal (OAML) . Methods: Between April 2008 and April 2019, 109 patients with initial mucosa-associated lymphoid tissue confining to ocular adnexal were evaluated and followed-up, and the prognosis of various initial treatment regimens were examined. Results: A total of 36 patients underwent complete surgical resection of the lesions, and 73 patients had residual lesions after surgery, of which 37 patients chose watchful waiting, and 36 patients chose treatment. The treatment regimen included local radiotherapy and systemic treatment (chemotherapy, immunochemotherapy, the combination of radiotherapy and chemotherapy, etc.) , and no serious toxic and side effects were observed in patients receiving systemic treatment. The median follow-up time was 61 (10-142) months. The 5-year and 10-year progression-free survival (PFS) of monocular involvement patients were 78.2% and 76.0% . The 5-year and 10-year PFS rates of patients with binocular involvement were 64.4% and 23.5%. There was significant diference in PFS between patients with monocular and binocular involvement (P=0.010) . Patients who received additional treatment had higher PFS than those patients in the watchful waiting group (P=0.046) . The 5-year PFS was 71.4% and 90.1% among patients in the watchful waiting group and those who received additional treatment, whereas the 10-year PFS was 63.5% and 75.1% , respectively. Patients with OAML were still a risk of disease progression after 5 years. Conclusions: Patients with binocular involvement OAML at the start of the disease had a poor prognosis, but treatment could reduce the risk of recurrence/progression. Systemic therapy is one of the first-line treatment options for patients with OAML, who require long-term monitoring.

Análise do perfil clínico de pacientes portadores de neoplasia ocular escamosa atendidos em hospital referência de oculoplástica / Analysis of the clinical profile of patients with squamous ocular neoplasms attended at a reference hospital of oculoplastics

RESUMO Objetivo Analisar o perfil clínico de pacientes portadores de neoplasias escamosas da superfície ocular. Métodos Foram avaliados os principais fatores de risco envolvidos na gênese das neoplasias escamosas da superfície ocular, as características clínicas dos pacientes e os hábitos comportamentais associados. Foram incluídos neste trabalho de coorte histórica 80 pacientes com diagnóstico anatomopatológico de neoplasia escamosa da superfície ocular atendidos entre os anos de 2010 e 2020 em um hospital referência em oculoplástica e segmento anterior de Santa Catarina. Os dados clínicos e desfechos foram avaliados por meio da análise de prontuário e entrevista, sendo posteriormente tabulados no Excel e submetidos à analise estatística por meio do software Statistical Pakage for the Social Sciences, versão 16. Resultados Foi observado que 73,8% (n=59) eram do sexo masculino. A média de idade da amostra foi de 62 anos. Quanto ao fototipo de pele, de acordo com a escala de Fitzpatrick, constatou-se que a maioria apresentou os fototipos 1 e 2 (22; 27,5% e 44; 55%, respectivamente). Em relação à exposição ocupacional ao sol/radiação, 48% (n=60) apresentaram história de exposição ocupacional, sendo que, destes, 28 pacientes trabalhavam no setor de agricultura. Dos pacientes da amostra, 33 (41,2%) apresentavam histórico pessoal de neoplasias de pele, sendo que, destes, três apresentavam diagnóstico de xeroderma pigmentoso. Quanto ao hábito de uso de fatores de proteção solar, 61% (n=49) da amostra negou o hábito. Foi evidenciada associação estatisticamente significativa entre o hábito de usar fatores de proteção solar e histórico pessoal de neoplasias de pele. Em relação ao tipo de neoplasia escamosa, a maioria dos pacientes (72; 90%) apresentou diagnóstico anatomopatológico de carcinoma espinocelular ocular. Conclusão O perfil clínico epidemiológico dos pacientes portadores de neoplasias escamosas da superfície ocular neste estudo, predominantemente de carcinoma espinoceular ocular, foi de homens, idosos, de pele clara (fototipo 2) e com histórico importante de exposição aos raios solares ultravioleta A e B. Comorbidades imunodepressoras (HIV e transplante de órgão sólido) e doenças dermatológicas (albinismo e xeroderma pigmentoso) associaram-se ao aparecimento das neoplasias escamosas da superfície ocular em idade mais precoce. Em pacientes com histórico pessoal prévio de neoplasias de pele, foi evidenciado o hábito de uso de fatores de protetor solar mais presente em relação aos demais.

ABSTRACT Objective To analyze the clinical profile of patients with ocular surface squamous neoplasms (OSSN). Methods The main risk factors involved in the genesis of the ocular surface squamous neoplasms, the clinical features, and the behavioral habits associated were evaluated. This historical cohort study included 80 patients with anatomopathological diagnosis of OSSN who were treated between 2010-2020 at a reference hospital in oculoplastic and anterior segment in Santa Catarina. The clinical data and outcomes were evalated through the analysis of medical records and interviews, being later tabulated in Excel and analyzed using the SPSS 16 software. Results Regarding the clinical profile of the patients in the sample, 73.8% (n = 59) were male. The mean age of the sample was 62 years old. As for the skin phototype, according to the Fitzpatrick scale, most of the sample presented the phototype 1 and 2 (27.5% n = 22; and 55% n = 44 respectively). Regarding occupational exposure to the sun / radiation, 48% (n = 60) had history of occupational exposure, and of these, 28 patients worked in the agricultural area. Of the patients of the sample, 33 (41.2%) had a personal history of skin neoplasms, and of these, 3 had diagnosis of xeroderma pigmentosum. As for the habit of using sun protection factors, 61% (n = 49) of the sample denied the habit. A statistically significant association was evidenced between the habit of using sun protection factors and people's history of skin cancer. Regarding the type of squamous neoplasia, most patients in the 90% sample (n = 72) had an anatomopathological diagnosis of ocular squamous cell carcinoma. Conclusion The clinical epidemiological profile of patients with OSSN in this study, predominantly ocular squamous cell carcinoma, was men, elderly, fair-skinned (phototype 2) and with an important history of exposure to UVA and UVB rays. Immunosuppressive comorbidities (HIV, solid organ transplant) and dermatological diseases (albinism, xeroderma pigmentosum) are associated with the appearance of OSSN at an early age. In patients with a previous personal history of skin neoplasms, the habit of using sunscreen factors was more present than in the other patients.

Características y tendencias de la mortalidad por cáncer de ojo y anexos en Chile / Characteristics and trends in mortality from eye and ocular adnexal cancer in Chile

Material y métodos Se realizó un estudio de cohorte retrospectiva para analizar la tasa de mortalidad ajustada por edad según sexo y grupos de edad. Con estos datos se efectuó un análisis de la tendencia para la tasa de mortalidad estandarizada usando el análisis de regresión joinpoint, permitiendo estimar el porcentaje de cambio anual (PCA) para hallar cambios significativos en las tendencias. Resultados 407 personas (201 hombres y 206 mujeres) murieron por estas causas durante 1990-2018. La tasa de mortalidad tiene presentación bimodal: en la infancia y adultos mayores. Levemente más alta en hombres que mujeres (tasa estandarizada por edad: 0,12 vs 0,08 por 100.000, respectivamente) pero observándose una baja del 53% en ambos sexos. Se registró una caída estadísticamente significativa en el PCA de -3,43% anual en ambos sexos, más en hombres (-3,31%) que mujeres (-3,66%). Conclusiones La mortalidad cáncer de ojo y anexos tiene picos en la infancia y luego en adultos mayores. En niños la mayoría corresponde a neoplasias malignas de retina y en adultos mayores de órbita. La mortalidad es mayor en hombres que mujeres, pero ambas tasas han ido en disminución asemejándose a las de países industrializados. A pesar de la ausencia de datos de incidencia, esta caída podría deberse al mejoramiento de protocolos diagnóstico y tratamiento, traduciéndose en menores tasas de mortalidad.

Purpose To describe and analyze the characteristics and trends of mortality from eye and adnexal cancer in Chile, by age and sex during 1990-2018. Material and methods A retrospective cohort study to analyze the age-adjusted mortality rate, by sex and age groups was carried out. With these data, a trend analysis for the standardized mortality rate was performed using a joinpoint regression analysis, allowing the annual percentage change (APC) to be estimated to find significant changes in trends. Results 407 people (201 men and 206 women) died due to these causes from 1990-2018. Mortality rate has a bimodal presentation: in childhood and in old adults. Slightly higher in men than women (age-standardized rate: 0,12 vs 0,08 per 100.000, respectively), but a decrease of 53% was observed in both sexes. During the period, there was a statistically significant fall in the APC of -3,43% per year in both sexes, more in men (-3,31%) than in women (-3,66%). Conclusions Mortality from malignant neoplasm of eye and adnexa peaks in childhood and later in older adults. In children, the majority correspond to malignant neoplasm of retina and in older adults of the orbit. Mortality is higher in men than women, but both rates have been decreasing, resembling those of industrialized countries. Despite the absence of incidence data in Chile, this decline could be due to the improvement of diagnostic protocols and treatment, leading to lower mortality rates.

Tumor de glándula lacrimal: a propósito de un caso / Lacrimal gland tumor: a case proposal

INTRODUCCIÓN: El carcinoma adenoide quístico (CAQ) es conocido por su lento crecimiento, su tendencia a la recurrencia local y al desarrollo de metástasis a distancia incluso décadas después del diagnóstico inicial, y a pesar de terapias agresivas. OBJETIVO: Presentar el caso de una paciente con CAQ de la glándula lagrimal, tumor muy infrecuente que representa casi el 10% de las lesiones orbitarias ocupantes de espacio. De éstas el 20-30% son de origen epitelial, de las cuales el 55% son lesiones benignas y el 45% malignas. El CAQ es el más común de los tumores epiteliales malignos de la glándula lagrimal (65%). CASO CLÍNICO: Presentamos el caso clínico de una paciente con CAQ de glándula lacrimal diagnosticado de forma incidental tras la realización de TAC desde la consulta de psiquiatría. RESULTADOS Y CONCLUSIONES: El síntoma de presentación más frecuente suele ser la proptosis, acompañada o no de dolor, aunque también puede presentarse como ptosis mecánica, reducción de visión y diplopía. La cirugía radical no ha demostrado mejorar la supervivencia o reducir la recurrencia local en comparación con un abordaje quirúrgico, más conservador en pacientes con tumores de menor tamaño y sin afectación ósea. Las mayores tasas de supervivencia se han conseguido, en pacientes tratados con quimioterapia, con quimioterapia citorreductiva intra-arterial seguida de exenteración orbital y radioterapia.

INTRODUCTION:The adenoid cystic carcinoma (ACC) is known for its slow growth, a tendency to local recurrence and the development of distant metastases even decades after the initial diagnosis, and despite aggressive therapies. AIM:We present the case of a patient with a lacrimal gland tumor. They are very rare tumors that represent almost 10% of space-occupying orbital lesions, of which 20-30% are of epithelial origin, of these, 55% are benign and 45% are malignant. The ACC is the most common malignant epithelial tumor (65%). CASE REPORT :We present the clinical case of a patient with ACC of the lacrimal gland incidentally diagnosed after performing a CT scan from the psychiatric office. RESULTS AND CONCLUSIONS:The most frequent presentation symptom is usually proptosis, accompanied or not accompanied by pain, although it can also occur as mechanical ptosis, vision reduction, and diplopia. Radical surgery has not been shown to improve survival or reduce local recurrence compared to a more conservative surgical approach in patients with smaller tumors and without bone involvement. The highest survival rates have been achieved, in patients treated with chemotherapy, with intra-arterial cytoreductors (IACC) followed by orbital exenteration and radiotherapy.

Oncocitoma em carúncula: relato de caso / Oncocytoma of the caruncle: a case report

RESUMO O oncocitoma é um tipo de neoplasia rara na prática clínica e descrito na literatura, principalmente quando localizado no olho. Quando localizado nos anexos oculares, é mais frequentemente na carúncula. Analisou-se o caso de uma paciente de 74 anos, caucasiana, que relatou desconforto visual no olho esquerdo, e cujo exame físico mostrou lesão tumoral na carúncula esquerda, com volume moderado, presença de neovascularização e secreção excessiva. A excisão cirúrgica da lesão foi realizada sob sedação, e a peça foi enviada para avaliação anatomopatológica. A lesão foi diagnosticada histologicamente como oncocitoma, sem malignidade, e a paciente não apresentou recidiva após o procedimento. Embora raro, esse tumor deve ser reconhecido pelos oftalmologistas, devido ao risco já relatado de desenvolvimento de adenocarcinoma.

ABSTRACT Oncocytoma is a neoplasm rarely observed in clinical practice and reported in the literature, especially when located in the eye. When described in the ocular adnexa, it is most often located in the caruncle. The case of a 74-year-old Caucasian female patient is reported. She complained of visual discomfort in the left eye, and physical examination showed a tumoral lesion in the left caruncle, of moderate volume, presence of neovascularization, and excessive secretion. Surgical excision of the lesion was performed under sedation, and the specimen was sent for pathological examination. The lesion was histologically diagnosed as oncocytoma with no malignancy, and the patient presented no recurrence after the procedure. Although rare, this tumor must be recognized by ophthalmologists due to the risk of developing adenocarcinoma, as already reported.

Intraconal orbital dermoid cyst: a rare location

Intraconal dermoid cysts are very unusual in routine clinical practice. Clinical symptoms depend upon the site and extension of the lesion. Though rare, proptosis, diplopia, and orbital pain are the presenting symptoms encountered in patients with an intraorbital dermoid cyst. Although radiology can be diagnostic, a complete correlation with the final histopathology is always mandatory for its confirmation. Endoscopic excision of the cyst ensures a complete cure for the disease without any intraoperative/postoperative complications.

Novel low-cost approach to the treatment of ocular surface squamous neoplasia using pattern scanning laser photocoagulation / Nova abordagem de baixo custo para neoplasia escamosa da superficie ocular usando fotocoagulação tipo pattern scanning

ABSTRACT Purpose: To evaluate the safety and 12-month effect of treatment with pattern scanning laser photocoagulation for ocular surface squamous neoplasia in a low-resource setting with extremely limited access to an operating room. Methods: Adult patients with a clinical diagnosis of ocular surface squamous neoplasia underwent a complete ophthalmologic examination. After topical anesthesia and instillation of toluidine blue 1%, the lesion was treated using pattern scanning photocoagulation for a duration time that varied from 20 to 100 ms and power from 600 to 1,800 mW. Patients were examined on a weekly basis for the first month and underwent weekly retreatment of the remaining lesions, as necessary. Patients had a minimum follow-up of 12 months. Results: Thirty-eight patients (38 eyes) were included. All patients had clinical ocular surface squamous neoplasia that was confirmed by impression cytology. The age of patients ranged from 40 to 83 years (average: 65.5 years) and 28 of them were males (74%). The patients were divided into two groups: group I (immunocompetent) and group II (immuno­suppressed). In group I, 23 patients (74%) presented complete response with lesion control after laser treatment alone. In group II, two of seven patients (28%) showed treatment response during the follow-up. The average number of treatments was 2.5 (one to six laser treatments). Procedures were well tolerated. Conclusion: Short-term results of the laser photocoagulation approach for the treatment of ocular surface squamous neoplasia conjunctival lesions were favorable, with a 74% success rate observed in immunocompetent patients. This novel strategy is a less resource-intensive alternative that could demonstrate its usefulness in settings with shortages in operating rooms and in recurrent cases. Studies with longer follow-ups and larger sample sizes are warranted to confirm our findings and evaluate the effectiveness of laser treatment in association with topical chemotherapy.

RESUMO Objetivo: Avaliar a segurança e o efeito de 12 meses de tratamento com fotocoagulação pelo pattern scanning laser para neoplasia escamosa da superfície ocular em um ambiente com poucos recursos e acesso extremamente limitado a um tratamento cirúrgico. Métodos: Pacientes adultos com diagnóstico de neoplasia escamosa de superfície ocular foram submetidos a exame oftalmológico completo. Após anestesia tópica e instilação de azul de toluidina 1%, a lesão foi tratada com laser por um tempo de duração que variou de 20 a 100 ms e potência de 600 a 1800 mW. Os pacientes foram examinados semanalmente durante o primeiro mês e fo­ram retratados semanalmente das lesões restantes, conforme necessário. Os pacientes tiveram um seguimento mínimo de 12 meses. Resultados: Trinta e oito pacientes (38 olhos) foram incluídos no estudo. Todos os pacientes apresentaram neoplasia escamosa da superfície ocular clínica, confirmada por citologia de impressão. A idade dos pacientes variou entre 40 e 83 anos (média de 65.5 anos) e 28 deles eram do sexo masculino (74%). Os pacientes foram divididos em dois grupos: Grupo I (imunocompetente) e grupo II (imunossuprimido). No grupo I, 23 pacientes (74%) apresentaram resposta completa com o controle da lesão após o tratamento com laser. No grupo II, dois dos sete pacientes (28%) apresentaram resposta ao tratamento durante o acompanhamento. A média de aplicações de laser foi de 2,5 (1 a 6 aplicações). Os procedimentos foram bem tolerados. Conclusões: Os resultados a curto prazo da abordagem de fotocoagulação a laser para o tratamento das lesões conjuntivais de neoplasia escamosa de superfície ocular foram favoráveis, com uma taxa de sucesso de 74% observada em pacientes imunocompetentes. Essa nova estratégia é uma alternativa menos intensiva em recursos que pode demonstrar sua utilidade em ambientes com escassez de salas cirúrgicas e em casos recorrentes. Estudos com acompanhamentos mais longos e amostras maiores são necessários para confirmar nossos achados e avaliar a eficácia do tratamento a laser asso­ciado à quimioterapia tópica.

Morning glory disc anomaly associated with large facial infantile hemangioma as the presenting signs of PHACE syndrome / Anomalia de Morning Glory associada à extenso hemangioma infantil como apresentação da Síndrome PHACE

ABSTRACT Infantile hemangioma, the most common benign tumor in infancy, is usually an isolated condition occurring in many different locations in the body. However, large infantile hemangioma may be associated with other systemic malformations, including central nervous system, cerebrovascular, cardiac, and ophthalmology abnormalities, a condition termed PHACE syndrome. In this paper, we describe a case of PHACE syndrome that was presented with the unique association of a large facial infantile hemangioma and morning glory anomaly.

RESUMO O hemangioma infantil é a causa mais comum de tumor benigno na infância e usualmente é uma condição isolada podendo ocorrer em diferentes regiões do corpo. No entanto, hemangiomas infantil extensos podem ser associados com outras malformações sistêmicas incluindo anomalias no sistema nervoso central, cerebrovasculares, cardíacas e oftalmológicas, uma condição denominada síndrome PHACE. Neste trabalho, descrevemos o caso de um paciente com síndrome PHACE que se apresentou com um extenso hemangioma facial e anomalia de "morning glory".

Melanoma uveal de cuerpo ciliar / Uveal melanoma of ciliary body

RESUMEN El objetivo de este reporte de caso fue identificar las características de un nevo abultado conjuntival en una paciente femenina de 72 años de edad. Se muestran las pruebas complementarias realizadas para llegar al diagnóstico de melanoma conjuntival, que consiste en un tumor poco frecuente, el cual constituye el 2 por ciento de todos los tumores del ojo. Las células involucradas son los melanocitos del epitelio conjuntival. Un factor de riesgo para esta entidad puede ser la exposición a la luz ultravioleta; sin embargo, esto no está bien determinado. La mayoría de los casos se originan de una melanosis adquirida primaria (50-70 por ciento). La presentación más común es una lesión pigmentada, unilateral, elevada, gruesa, con vasos sanguíneos y áreas de melanosis a su alrededor. Su diagnóstico se realiza con la sospecha clínica que se confirma con el estudio histopatológico. El tratamiento en la actualidad es la excisión local, seguida de crioterapia, radioterapia o quimioterapia. La enfermedad matastásica ocurre en el 11 - 42 por ciento y en el 20 - 52 por ciento de los pacientes en un seguimiento de 5 y 10 años, respectivamente(AU)

ABSTRACT The objective of this case report is to describe the characteristics of a conjunctival bulging nevus in a 72-year-old female patient and the complementary tests that were performed to reach the diagnosis of conjunctival melanoma. Conjunctival melanoma is a rare tumor, which account for 2 percent of all eye tumors. The cells involved are the melanocytes of the conjunctival epithelium. A risk factor for this entity may be exposure to ultraviolet light. However, it has not been precisely described. Most cases originate from a primary acquired melanosis (50-70 percent). The most common presentation is a pigmented, unilateral, elevated, thick, lesion with blood vessels and areas of melanosis around it. Its diagnosis is made with the clinical suspicion confirmed with the histopathological study. Current treatment is local excision, followed by cryotherapy, radiotherapy, or chemotherapy. Metastatic disease occurs in 11-42 percent and 20-52 percent of patients in a 5-year and 10-year follow-up, respectively(AU)

Caracinoma de células renales con metástasis ocular como primera manifestación clínica. Informe de un caso / Renal cell carcinoma with ocular metastasis as the first clinical manifestation: Case report

Introducción: El carcinoma de células renales representa el 2-3% de todos los cánceres. Alrededor del 30% de los pacientes presentan metástasis en el momento del diagnóstico y otro 30% de los pacientes con enfermedad localizada desarrollan recurrencia o metástasis. El sitio más común de metástasis es el pulmón, el hueso y el hígado. Objetivo: presentar una paciente con metástasis ocular como una presentación atípica de carcinoma de células renales. Caso clínico: Femenino de 41 años, tres meses previos inició con dolor ocular urente, fotopsias, hemianopsias y disminución de la agudeza visual del ojo derecho. La exploración física dirigida mostró tumor subretiniano. Se le realizó enucleación del ojo afectado y colocación de implante, con hallazgo de tumor intracelar y reporte histopatológico de carcinoma de células claras. Los estudios de extensión mostraron tumor renal izquierdo. Se le realizó nefrectomía radical izquierda con adrenalectomía derecha en un mismo tiempo quirúrgico. Discusión: El carcinoma de células renales metastásico tiene un pronóstico malo, la sobrevida al año es de 48% y a los 5 años de 9%. La metástasis única al momento del diagnóstico tiene pronóstico mejor que las múltijples. Conclusiones; El CCR puede metastatizar a sitios raros como el globo ocular entre otros (AU)

Introduction: Renal cell carcinoma accounts for 2-3% of all cancers. About 30% of patients have metastases at the time of diagnosis, other 30% with the patients with localized disease develop recurrence or metastasis. The most common site of metastasis are lungs, bones and liver. Objetive: to present a patient with ocular metastasis as an atypical presentation of renal cell carcinoma. Clinical case: Forty one years old female, three months before, began with burning eye pain, photopsies, hemianopsies and decreased visual acuity of the right eye. The directed physical examination showed subretinal tumor. Enucleation of the afected eye and implant placement was performed, with intracelar tumor finding and histopathological report of clear cell carcinoma. The extension studies showed left renal tumor. Left radical nephrectomy was performed with right adrenalectomy in the same surgical time. Discussion: Metastatic renal cell carcinoma has a poor prognosis, the survival rate is 48% at 5 years and 9% at 5 years. The single metastasis at the time of diagnosis has a better prognosis than multiple ones. Conclusions: RCC can metastasize to rare sites such as the eyeball among others (AU)

The Amazon Ocular Oncology Center: The first three years / Centro de Oncologia Ocular do Amazonas: primeiros três anos

ABSTRACT Purpose: To evaluate the first three years of The Amazon Ocular Oncology Center, the first ocular cancer center in the North of Brazil. Methods: Here, we report patient information including patients' age, gender, diagnosis, treatment, and city of origin. Results: Two hundred and twenty-one patients were included on this study: 160 (72%) patients came from the city of Manaus, 52 (24%) from other cities in Amazonas, and 9 (4%) from other states. Of the 221 patients, 150 (68%) were afflicted with benign lesions and the remaining 71 (32%) had malignant lesions. Benign diagnosis included pterygium, chalazium, conjunctival nevus, and papilloma, cataract, and retinal detachment. Of the malignant cases, squamous cell carcinoma (SCC) of the conjunctiva was the most frequent with 43 cases (60%). Other diagnoses included choroidal melanoma (8 cases, 11%), retinoblastoma (7 cases, 9%), lymphomas (5 cases, 7%), basal cell carcinomas of the eyelid (4 cases, 5%), conjunctival melanoma (2 cases, 2%), and Kaposi sarcomas (1 case, 1%). Of the 43 patients with SCC, the mean age was 62 years old, and 30 (69%) were male; 29 patients (67%) were treated with an excisional biopsy, and 14 (33%) were treated with neoadjuvant topic chemotherapy, followed by surgery.

RESUMO Objetivo: Reportar sobre os primeiros três anos do Centro de Oncologia Ocular do Amazonas, primeiro centro de oncologia ocular na região Norte do Brasil. Métodos: Relatamos informações de diagnóstico, idade, sexo, tratamento e cidade de origem dos pacientes atendidos nos 3 primeiros anos. Resultados: Identificamos 221 pacientes, dos quais 160 (72%) eram da cidade de Manaus, 52 (24%) de outras cidades do Amazonas e 9 (4%) de outros estados. Dos 221 casos, 150 (68%) eram lesões benignas e 71 (32%) malignas. Lesões benignas incluíram pterígio, calázio, nevus e papiloma de conjuntiva, catarata e descolamento de retina. Das lesões malignas a mais comum foi o carcinoma escamoso de conjuntiva com 43 casos (60%). Outros diagnósticos incluíram melanoma de coróide (8 casos, 11%), retinoblastoma (7 casos, 9%), linfomas (5 casos, 7%), carcinoma da pálpebra (4 casos, 5%), melanoma da conjunctiva (2 casos, 2%) e sarcoma de Kaposi (1 caso, 1%). Dentre os CEC de conjuntiva, a idade media foi de 62 anos e 30 pacientes (69%) eram do sexo masculino. Vinte e nove casos (67%) foram tratados com biópsia excisional e 14 (33%) com quimioterapia tópica neoadjuvante seguida de cirurgia.
