ABSTRACT

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.

ABSTRACT

ABSTRACT A 45-year-old man presented with a 3-month history of a mass located in the caruncle of his right eye. An incisional biopsy had been performed one month prior by another specialist, and the histopathology report showed basal cell carcinoma. The mass was completely excised with a 2 mm safety margin, and the large conjunctival defect was reconstructed with one sheet of amniotic membrane allograft. A histological diagnosis of pilomatrix carcinoma was established. To prevent recurrence after surgery, we added bevacizumab (25 mg/mL, 1.25 mg/mL per drop) eye drops four times per day for three months. At the one-year follow-up, the patient showed no evidence of local recurrence or distant metastasis after initial excision and remains under close follow-up. Pilomatrix carcinoma should be considered in the differential diagnosis of a caruncular mass.


RESUMO Um homem de 45 anos apresentou história de massa na carúncula no olho direito durante 3 meses. Uma biópsia incisional foi realizada 1 mês antes por outro especialista e o laudo histopatológico mostrava carcinoma basocelular. A massa foi completamente excisada, com uma margem de segurança de 2 mm, e a grande lesão conjuntival foi reconstruída com uma folha de aloenxerto de membrana amniótica. Foi estabelecido um diagnóstico histológico de carcinoma pilomatricial. Para evitar a recorrência após a cirurgia, adicionamos colírio de bevacizumabe (25 mg/mL, 1,25 mg/mL por gota) quatro vezes ao dia durante três meses. No seguimento de 1 ano, o paciente não apresentou evidência de recidiva local ou metástase distante após a excisão inicial e continua sob acompanhamento próximo. O carcinoma pilomatricial deve ser considerado no diagnóstico diferencial de uma massa caruncular.

ABSTRACT

ABSTRACT Here, we present a case in which extensive bulbar conjunctival Kaposi's sarcoma was the initial presentation of human immunodeficiency virus in a 36-year-old man. The patient had a 3-month history of recurrent self-limited inferior conjunctiva hyperemia in the right eye, and presented with a painless bullous lesion in the right inferior bulbar conjunctiva persisting for 15 days. Surgical incision biopsy was performed at five locations and revealed a pattern compatible with Kaposi's sarcoma. Serologic testing was positive for human immunodeficiency virus; however, the patient had no other symptoms, or knowledge of human immunodeficiency virus infection. This case highlights the need to consider Kaposi's sarcoma as an early presentation of human immunodeficiency virus even if the patient denies infection.


RESUMO Este relato de caso apresenta um sarcoma de Kaposi extenso na conjuntival bulbar como a apresentação inicial do vírus da imunodeficiência humana em um homem de 36 anos de idade. O paciente tinha história de hiperemia na conjuntiva inferior do olho direito há 3 meses, autolimitada e recorrente e de surgimento de uma lesão bolhosa indolor no mesmo local 15 dias antes da sua apresentação. Uma biópsia incisional cirúrgica foi realizada e revelou um padrão compatível com sarcoma de Kaposi. Teste sorológico posterior revelou positividade para o vírus da imunodeficiência humana, no entanto, o paciente não apresentou outros sintomas, sinais ou conhecimento prévio sobre a infecção. Como conclusão deste caso, deve se ressaltar que a suspeita do diagnóstico do sarcoma de Kaposi deve ser levantada ainda que na apresentação inicial do vírus da imunodeficiência humana ou mesmo naqueles ainda sem este diagnóstico.

ABSTRACT

Se presenta el caso clínico de una paciente de 62 años de edad, mestiza, de procedencia rural, quien había sido atendida 3 años atrás en consulta de oftalmología por un tumor de conjuntiva en el ojo izquierdo. Asistió nuevamente a consulta por dicha razón, pero esta vez además existía sangrado profuso y daño grave de las estructuras oculares. Se le realizaron varios exámenes, entre ellos rayos X de órbita, ecografía ocular, tomografías de órbita (con contraste) y cráneo, así como biopsia de la lesión exofítica y estudio inmunohistoquímico. El diagnóstico histológico definitivo fue carcinoma epidermoide de conjuntiva, por lo que se decidió realizar exéresis orbitaria, cirugía plástica reconstructiva y, posteriormente, radioterapia y quimioterapia. La paciente evolucionó favorablemente y fue controlada la diseminación de la neoplasia maligna, lo que además pudo evitarse si la atención médica inicial hubiese sido oportuna.


The case report of a 62 years mestiza patient of rural origin is presented, who had been assisted 3 years ago in the ophthalmology service due to a tumor of conjunctive in the left eye. She went again to the service for this reason, but this time it also existed profuse bleeding and serious damage of the ocular structures. Several exams were carried out, among them orbit X rays, ocular echography, orbit and skull tomographies (with contrast), as well as biopsy of the exofitic lesion and immunohistochemical study. The definitive histologic diagnosis was squamous cell carcinoma of conjunctive, reason why it was decided to carry out orbit exeresis, reconstructive cosmetic surgery and, later on, radiotherapy and chemotherapy. The patient had a favorable clinical course and the dissemination of the malignancies was controlled, what could also be avoided if initial medical care might have been opportune.

ABSTRACT

ABSTRACT Purpose: To evaluate the clinical results of patients treated by amniotic membrane transplantation (AMT) following excision of conjunctival and limbal tumors. Methods: A total of 14 eyes of 14 patients who underwent AMT after total lesion-free tumor excision and perilesional cryotherapy were evaluated. Results: The excised tumors comprised 7 conjunctival intraepithelial neoplasia, 5 conjunctival nevus, 1 primary acquired melanosis, and 1 squamous cell carcinoma. Limbus was involved in 10 cases, whereas cornea was involved in 6 cases. The average measurement of the tumor base was 14.8 mm (range 6-20 mm, SD 16 mm). The mean follow-up time period was 17.5 months (range 6 -60 months, SD 20 months). Complete healing occurred in eight eyes, but limbal cell deficiency developed in two eyes. Four cases had recurrence and were treated with the same surgical and medical procedures; during follow-up after recurrence, superficial peripheral vascularization and corneal scar were noted to have developed. Conclusions: AMT was effective for reconstruction of tissue defect after excision and cryotherapy of limbal and conjunctival tumors. In most of these cases, complete healing was achieved with a smooth, stable, and translucent surface.


RESUMO Objetivo: Avaliar os resultados clínicos de pacientes tratados com transplante de membrana amniótica (TMA) após a excisão de tumores conjuntival e limbar. Métodos: Foram avaliados 14 olhos de 14 pacientes submetidos a transplante de membrana amniótica após excisão total de tumor e crioterapia perilesional. Resultados: Os tumores que foram excisados podem ser classificados como neoplasia intraepitelial conjuntival em 7, nevus conjuntival em 5, melanose adquirida primária e carcinoma espinocelular em 1 caso cada. O limbo foi envolvido em 10 casos e a córnea foi envolvida em 6 casos. A medida média da base do tumor foi de 14,8 mm (6-20, DP 16). O tempo médio de seguimento foi de 17,5 meses (6-60, DP 20). A cicatrização completa ocorreu em 8 olhos e deficiência de células limbares ocorreu em 2 olhos. A recorrência foi diagnosticada em 4 casos e tratada com o mesmo procedimento cirúrgico e médico e, após essa recorrência, a vascularização periférica superficial e a cicatriz corneana desenvolveram-se em 4 casos durante o seguimento. Conclusões: O transplante de membrana amniótica é um método eficaz para a reconstrução do defeito do tecido após a excisão de tumores limbares e conjuntivais com a combinação de crioterapia. Na maioria destes casos, a cicatrização completa pode ser conseguida com uma superfície lisa, estável e transparente.

ABSTRACT

RESUMO Objetivo: Avaliar a segurança e eficácia de três técnicas distintas para o tratamento de neoplasia intraepitelial córneo-conjuntival. Métodos: Vinte e seis pacientes, 11 mulheres e 15 homens, com idade entre 32 e 88 anos (média 64,84 anos), atendidos entre 1999 e 2014, foram incluídos neste estudo. Todos os pacientes foram submetidos à exérese da lesão com margem de segurança de 4mm e crioterapia a 2mm do limbo. Conforme o tratamento complementar, os pacientes foram divididos em três grupos: Grupo 1 (8 olhos): recobrimento conjuntival e 2 ciclos de mitomicina C 0,02% (MMC) 4x/dia por 10 dias, com intervalo de 30 dias entre os ciclos. Grupo 2 (9 olhos): recobrimento com membrana amniótica e 3 ciclos de MMC 3x/dia por 10 dias, com intervalo de 10 dias entre o 1º e o 2º ciclo e 30 dias entre 2º e o 3º ciclo. Grupo 3 (9 olhos): recobrimento com membrana amniótica sem o uso de MMC. O acompanhamento dos pacientes variou de 3 meses a 14 anos (média: 4 anos). Resultados: Vinte e três pacientes apresentaram erradicação da lesão com um único tratamento. Três pacientes do Grupo 3 apresentaram recidiva da lesão após 3 meses, 6 meses e 1 ano do tratamento. Dois deles foram retratados pela técnica 1, sem nova recidiva após seguimento de 3 e 4 anos; o outro paciente foi submetido à enucleação. Não foram observados efeitos colaterais relacionados ao uso da mitomicina C durante o seguimento. Conclusão: Após exérese da lesão e crioterapia, os pacientes tratados com recobrimento conjuntival ou membrana amniótica associado à mitomicina C mostraram tendência a resultados mais eficazes.


ABSTRACT Purpose: To evaluate the safety and efficacy of three different techniques for the treatment of conjunctival-corneal intraepithelial neoplasia. Methods: Twenty-six eyes of 26 patients, 11 women and 15 men were included in a nonrandomized, retrospective, observational case series. Mean patient age was 64 years (range, 32-88 years).All patients were treated from 1999 to 2014. Mean postoperative follow-up was 4 years (range, 3 months to 14 years). All patients underwent excision of the lesion with a 4-mm safety margin and a 2-mm from the limbus cryotherapy. As further treatment the patients were divided into three groups: Group 1 (8 eyes): conjunctival autograft and 2 cycles of mitomycin C 0.02% (MMC) eye drops, four times daily for 10 days with an interval of 30 days between cycles. Group 2 (9 eyes): amniotic membrane (AM) graft and 3 cycles of MMC eye drops, three times daily for 10 days with an interval of 10 days between the 1st and 2nd cycle and 30 days between the 2nd and 3rd cycle. Group 3 (9 eyes): AM graft without MMC eye drops. Results: After a single treatment, the lesions were eradicated in twenty-three patients. Recurrence was noted in three patients from Group 3 at 3 months, 6 months and 1 year after treatment. Two of them were retreated by the technique used in Group 1 without further recurrence; the other patient underwent enucleation. No adverse effects related to the use of mitomycin C were observed during. There were no side effects related to the use of mitomycin C during follow-up. Conclusion: After surgical excision and cryotherapy, patients treated with conjunctival or amniotic membrane graft associated with mitomycin C, showed a tendency to more effective results.

ABSTRACT

ABSTRACT Our patient was a 34 year-old male who presented with a painless conjunctival mass that had developed 3 months before his first visit. On performing slit-lamp biomicroscopy, a lobulated pink-yellowish solid mobile mass was observed on the nasal bulbar conjunctival surface of his left eye. The tumor was excised, and histopathologic examination of the tumor revealed a sebaceous adenoma. Systemic examination was normal. No recurrence was observed during the 24-month follow-up period. Sebaceous adenoma of the bulbar conjunctiva is an extremely rare benign tumor, which may be observed to be isolated in the absence of malignancy.


RESUMO Nosso paciente era um homem de 34 anos que apresentou uma massa conjuntival indolor desde há 3 meses antes da primeira consulta. Na biomicroscopia por lâmpada de fenda, observa-se uma massa rosa-amarelada, sólida, móvel e lobulada na superfície conjuntival bulbar nasal, em seu olho esquerdo. O tumor foi retirado e o exame histopatológico demonstrou um adenoma sebáceo. O exame sistêmico era normal. Nenhuma recidiva foi observada durante os 24 meses de acompanhamento. Adenoma sebáceo da conjuntiva bulbar é um tumor benigno extremamente raro e pode ser visto isolado, sem quaisquer doenças malignas associadas.

ABSTRACT

ABSTRACT Pilomatrixoma is a rare benign tumor, which usually affects young women in the head and neck region. The eyelid is a common site of the disease, though it is very rare in the tarsal conjunctiva.The pilomatrixoma has clinical pleomorphism, which confuses this disease with other similar conditions. The diagnosis is made by pathological examination in most cases. The treatment is surgical, performed by total excision of the lesion with clear margins and recurrence is very uncommon.We present an unusual case of probable recurrent pilomatrixoma in the left upper tarsal conjunctiva.


RESUMO O pilomatricoma é uma neoplasia benigna rara, geralmente acomete mulheres jovens, ocorrendo na região da cabeça e pescoço. A pálpebra é um local comum de aparecimento do pilomatricoma, contudo, seu aparecimento na conjuntiva tarsal é muito raro. O diagnóstico é feito pelo exame anátomo-patológico na maioria dos casos, pois seu pleomorfismo clínico o confunde com outras alterações. O tratamento é cirúrgico, realizado por meio da exérese total da lesão com margens livres. São raros os casos de recidiva. Apresentamos um caso atípico de provável recidiva de pilomatricoma, localizado na conjuntiva tarsal superior à esquerda.

ABSTRACT

O melanoma conjuntival multifocal recidivado originado de nevus preexistente é extremamente raro, ocorrendo em uma pessoa para cinco milhões de habitantes. Seu estudo é de extrema relevância, devido sua potencial letalidade. Este estudo objetiva descrever um caso de melanoma conjuntival multifocal recidivado proveniente de nevus pigmentado preexistente ocorrido em Patos de Minas, MG. Este é um estudo de caso com revisão de literatura. O diagnóstico histopatológico e o estadiamento precoce da lesão conjuntival é de fundamental importância para designar a conduta frente ao paciente. O procedimento terapêutico mais utilizado nos dias atuais é a excisão cirúrgica com crioterapia adjuvante associada à mitomicina C. O prognóstico do melanoma conjuntival multifocal recidivado originado de nevus preexistente é o pior dentre todos os melanomas oculares, apresentando alta taxa de mortalidade, 12% a 20% em 5 anos e 30% em 10 anos de desenvolvimento patológico.


Recurrent multifocal conjunctival melanoma originated from preexisting nevus is extremely rare: it occurs in one out of five million individuals. The investigation of this disease is extremely important due to its potential lethality. Thus, this study aims to describe a case of recurrent multifocal conjunctival melanoma originated from preexisting pigmented nevus, which occurred in the city of Patos de Minas, state of Minas Gerais. This is a case study and literature review. Histopathological diagnosis and early staging of the conjunctival lesion is a key element on how to approach the patient. The treatment procedure most commonly used today is surgical excision with adjuvant cryotherapy and mitomycin C. The prognosis of recurrent multifocal conjunctival melanoma originated from preexisting nevus is the worst of all ocular melanomas, with high mortality rate: 12% to 20% within 5 years and 30% within 10 years of pathological development.

ABSTRACT

O tratamento das neoplasias conjuntivais, tradicionalmente, é a excisão cirúrgica associada à crioterapia. Devido às altas taxas de recidiva, aos riscos de excisões extensas como deficiência límbica e outras complicações na superfície ocular, estudos foram feitos com medicamentos como o Interferon-α2b para o tratamento deste tipo de neoplasia e suas recidivas.


The traditional treatment for conjunctival neoplasias is surgical excision associated with cryotherapy, but due to the high recurrence rates, risks of extensive excisions as limbal deficiency and other ocular surface complications, studies were made to evaluate drugs like Interferon-α2b to treat this kind of neoplasia and its recurrences.

ABSTRACT

Relato de caso de melanose primária adquirida unilateral em paciente do sexo feminino, de 59 anos, com cerca de quatro anos de evolução, associada a episódios de erosões recorrentes do epitélio corneano. A paciente foi submetida à exerese cirúrgica da conjuntiva alterada, ceratectomia superficial e uso de mitomicina-C tópica no pós-operatório. O exame anatomopatológico confirmou o diagnóstico de melanose primária adquirida, com atipias nucleares discretas a moderadas. Um ano após a cirurgia, a paciente não apresentou novos episódios de erosões recorrentes do epitélio corneano, sendo mantida apenas com o uso noturno de pomada lubrificante.


A case report of a 59 years old woman who has had ocular primary melanosis for four years, associated with episodes of corneal epithelial recurrent erosions. The patient underwent resection of the affected conjunctiva, superficial keratectomy and topical mitomicin C after the surgery. The pathologic examination confirmed the diagnosis of primary acquired melanosis, with mild to moderate nuclear atypia. One year after the treatment, she had only a small area of pigmented epithelium located in the lower corneal surface, showing no tendency to progression. She used lubricant ointment at night and did not have other epithelial erosions during the follow-up period.

ABSTRACT

Os autores relatam um caso de nevo de Reed, lesão que apresenta aspecto histológico de malignidade, mas tem evolução benigna. Paciente de 48 anos, masculino, cor parda, apresentava pterígio nasal no olho direito, associado a uma lesão pequena e pouco pigmentada localizada na cabeça do mesmo. Realizou-se exérese de ambos, sem intercorrências, sem sinais de recidiva. O exame histopatológico revelou lesão com bordas definidas, restrita ao epitélio, constituída por células fusiformes perpendiculares à superfície, com pigmentação melânica esparsa. O diagnóstico inicial foi nevo de Spitz, mas, posteriormente, chegou-se à conclusão que se tratava do nevo de células fusiformes de Reed. O presente relato é o segundo na literatura mundial e o primeiro no Brasil.


The authors report one case of nevus of Reed, which has histological aspect of malignancy, but a benign evolution. A 48-years-old brown skin male presented nasal pterygium in right eye, associated with a small and poorly pigmented lesion located on the pterygium head. Both were excised without complications and, currently, there is no recidivation. The histopathological examination revealed one lesion with defined edges, limited to the epithelium, consisted of spindle cells perpendiculars to the surface and with sparse melanin pigmentation. The initial diagnosis was Spitz nevus, but, afterwards, we concluded that was the spindle cell nevus of Reed. This report is the second in the international literature and the first in Brazil.

ABSTRACT

An 81-year-old woman with a raised pigmented nodule over her left cornea for 7 months duration was examined. Dark conjunctival pigmentation was observed in the upper bulbar fornix conjunctiva. She had previously undergone primary surgical excision of a malignant conjunctival melanoma four years earlier. The tumor separated easily from the corneal surface, but remained slightly attached to the corneoscleral surface. A corneoscleral lamellar dissection of 3 mm in width and 2 mm in depth as well as a corneoscleral lamellar keratoplasty for the reconstruction of the corneoscleral defect were performed. The wide upper bulbar and fornix conjunctiva were excised, and an amniotic membrane transplantation was performed. Biopsy revealed an invasive melanoma with a depth of 1 mm. Left, right, and inferior tumor margins of the corneoscleral lesion and the pigmentary lesion in the conjunctiva were free of the tumor. After surgery, 0.04% mitomycin was administered topically 4 times daily for 4 weeks. There was no recurrence 2 years after surgery, and systemic evaluation revealed no metastasis.

ABSTRACT

Purpose: To report the impression cytology features of conjunctival nevireported as more noticeable. Methods: 35 patients who reported that a conjunctival lesion had become more noticeable after color or size changewere enrolled. On slit-lamp xamination, a clinical diagnosis of nevus was made and lesions underwent impression cytology using acetate cellulose strips and a combined staining with PAS, H&E and Papanicolaou. At patient’s or parents’ request, excision of the lesion was performed and the tissue was submitted to histopathological study. Results: Impression cytology examination revealed nests or cluster of nevus cells within the epithelium layer containing or not mucous-secreting goblet cells in 32 cases (91.4%). Ten patients (28.5%) had the tumor removed and histopathological diagnosis was compound nevus in 8 eyes (1 from caruncle, 1 from plica semilunaris and 6 from bulbar conjunctiva) and subepithelial nevus from bulbar conjunctiva (2 eyes). Conclusion: Optical microscopy analysis of the impression cytology specimens confirmed the clinical diagnosis by demonstrating typical histopathological features of the superficial layers from conjunctival nevi in 91.4% of the cases. For amelanotic nevi IC can also allow a differential diagnosis from othernonpigmented lesions. The technique does not replace histopathologicalexamination, but additionally, may assist in evaluating nevus cells in children and adults.


Objetivo: Relatar as características da citologia de impressão de nevos conjuntivais referidos como mais perceptíveis. Métodos: Trinta e cinco pacientes que notaram uma lesão conjuntival que se tornou mais perceptível, por mudança de cor ou de tamanho, foram avaliados. Ao exame biomicroscópico foi feito o diagnóstico clínico de nevo, sendo obtidas amostrasde citologia de impressão das lesões com auxílio do papel filtro de acetato de celulose, coradas com PAS, H&E e Papanicolaou. Para os indivíduos que optaram também pela remoção da lesão, o tecido foi enviado para análise histopatológica. Resultados: O exame de citologia de impressão revelou ninhos ou blocos de células névicas na camada epitelial, acompanhados ou não de células caliciformes em 32 casos (91,4%). Dez pacientes (28,5%) tiveram a lesão removida, sendo o diagnóstico histopatológico de nevo composto (um na carúncula, um na prega semilunar e seis na conjuntiva bulbar) e nevo subepitelial (dois na conjuntiva bulbar). Conclusão: Aanálise pela microscopia óptica das amostras de citologia de impressão confirmou o diagnóstico clínico ao demonstrar características típicas das camadas superficiais do nevo conjuntivalem 91,4% dos pacientes. Nos nevos amelanóticos a citologia pode auxiliar no diagnóstico diferencial de outras lesõesnão pigmentadas. A técnica não substitui o exame histopatológico, mas pode ser útil na avaliação de células névicas emcrianças e adultos.

ABSTRACT

OBJETIVO: Investigar a utilização da membrana amniótica humana na reconstrução da superfície ocular após exérese de carcinoma de células escamosas da conjuntiva. MÉTODOS: A membrana amniótica foi captada a partir de parto cesárea, conservada em meio de preservação de córnea e glicerol 1:1 e armazenada a -80º C. Os critérios de inclusão foram: pacientes portadores de lesão proliferativa conjuntival com características de carcinoma de células escamosas (lesão esbranquiçada plana ou elevada com aspecto em "carne de peixe"), envolvendo conjuntiva, limbo e córnea. Oito olhos de 8 pacientes portadores de "carcinoma de células escamosas" da conjuntiva foram submetidos a cirurgia de exérese do tumor conjuntival, associado a transplante de membrana amniótica. Destes, 3 foram submetidos a epiteliectomia total da córnea e a transplante de limbo do olho contralateral. RESULTADOS: O tempo médio de seguimento foi de 17,8 meses (variação entre 10 e 35 meses). Cinco pacientes (71,4 por cento) obtiveram sucesso com o tratamento cirúrgico, com adequada reconstrução da área conjuntival retirada. Dois pacientes (28,6 por cento) obtiveram sucesso parcial, com presença de alterações cicatriciais leves (simbléfaro pequeno ou pequena fibrose). Um paciente foi excluído porque apresentou recidiva agressiva do tumor, com invasão intraocular, necessitando ser submetido a exenteração. CONCLUSÃO: O uso de membrana amniótica humana pode constituir uma importante opção para a reconstrução da superfície ocular após remoção de carcinoma de células escamosas.


PURPOSE: This study was designed to evaluate the use of human amniotic membrane for ocular surface reconstruction after conjunctival squamous cell carcinoma resection. METHODS: Amniotic membrane was obtained at the time of cesarean section and was preserved at -80ºC in glycerol and cornea culture media at a ratio of 1:1. The inclusion criteria were patients presenting proliferating lesions suggestive of squamous cell carcinoma (flat or elevated white lesions resembling "fish meat") that involve the conjunctiva, limbus and cornea. Eight eyes of 8 patients with conjunctival "squamous cell carcinoma" underwent tumor resection with amniotic membrane transplantation. Three of these cases underwent total corneal epitheliectomy and amniotic membrane transplantation associated with limbal autograft. RESULTS: Mean follow-up time was 17.8 months (range, 10-35 months). In four patients (71.4 percent) surgical treatment was successful, with good ocular surface stability. In two patients (28.6 percent) results were partially successful, with mild cicatricial alterations. One patient was excluded from the study due to aggressive tumor recurrence with intraocular invasion that needed to be removed with exenteration. CONCLUSION: This study suggests that amniotic membrane transplantation is a good alternative for ocular surface reconstruction after conjunctival squamous cell carcinoma resection.

ABSTRACT

To assess the results of brachytherapy in patients with recurrent or incomplete excised conjunctival squamous cell carcinoma [SCC] and malignant melanoma. Three patients underwent brachytherapy of one eye and one patient underwent brachytherapy of both eyes with ruthenium-106 [RU-106] plaques, all of them had a history of incomplete resection or recurrence of the tumor after surgery. All patients were male with an average age at diagnosis of 54 years [range, 34-76 years].The shape and the size of plaques were determined based on location and size of the suspected area. The plaque was inserted to deliver a target dose of 80-100 Gy in the region of conjunctival malignancy. The diagnosis was squamous cell carcinoma in three eyes and conjunctival melanoma in two eyes. All patients had surgical history of one to three previous excisions with or without cryotherapy before brachytherapy. There were microscopic residual tumors after excision in 2 eyes and recurrent lesion was evident in 3 other eyes. A mean dose of 95 Gy was delivered to the tumor bed. Complete tumor regression without any evidence of recurrent lesion was obtained in all five eyes. The patients were followed for 32 months on average [range, 18-42 months]. No radiation related complication was detected, with an exception of a dry eye in the last follow up. Brachytherapy with RU-106 plaque is an alternative method for treatment of selected patients with recurrent or residual conjunctival SCC and melanoma

ABSTRACT

São relatados três casos de neoplasia intra-epitelial córneo-conjuntival nos quais a mitomicina C foi utilizada em abordagens distintas de acordo com a situação clínica encontrada. Os pacientes selecionados foram atendidos no Departamento de Oftalmologia da Casa de Saúde Santo Inácio, com diagnóstico clínico e/ou histopatológico de neoplasia intra-epitelial córneo-conjuntival. Com base na apresentação clínica das lesões, utilizou-se a mitomicina C a 0,04 por cento em três abordagens terapêuticas distintas: 1) quimioablação pós-operatória; 2) quimiorredução pré-operatória; e 3) quimioablação isolada. Obteve-se regressão da lesão tumoral nos três casos, sem recorrência em tempo de seguimento variando de 18-29 meses. Hiperemia conjuntival em um dos casos foi a única complicação observada. A mitomicina C mostrou-se eficaz e segura para tratamento de neoplasia intra-epitelial córneo-conjuntival, possibilitando várias abordagens terapêuticas de acordo com as características das lesões.

ABSTRACT

Objetivo: Relatar caso atípico de mixoma da conjuntiva. Relato de caso: Paciente feminina, 11 anos de idade, com lesão em conjuntiva nasal esquerda notada há um mês. Ao exame a lesão não apresentava mobilidade, sendo feita suspeita de doença linfoproliferativa ou tumor estromal. Submetida à excisão cirurgica teve diagnóstico final de moxoma da conjuntiva. Apresentou recidiva da lesão dois meses após a primeira cirurgia, sendo submetida à nova excisão. Após 18 meses não havia sinal de doença recorrente. Comentários: O caso descrito é peculiar devido à baixa idade de apresentação, localização nasal, aderência ao tecido episcleral e ocorrência de recidiva da lesão.

ABSTRACT

A 65-year-old male patient presented with a rapidly increasing mass in his left eye. It did not show any intra-ocular extension as examined by slit lamp, gonioscopy, indirect ophthalmoscopy and ultrasonography, nor there was any sign of systemic metastasis. The mass was excised completely. Buccal mucous membrane grafting was done to cover up the lower forniceal area and conjunctival autograft taken from right eye and placed over upper fornix and bulbar area. Postoperative radiotherapy was suggested. Histopathological examination of the mass revealed the diagnosis of malignant melanoma of conjunctiva.
