    A young man presented with rapid, predominantly right-sided visual loss with a background of multifocal skin lesions. Visual acuity was right hand movements, left 6/5 Snellen, deteriorating to 6/38. He showed panuveitis with bilateral multifocal retinal infiltrates and retinal vasculitis. Multifocal brain lesions were identified. Biopsy of both skin and vitreous showed atypical lymphocytes, and immunohistochemistry confirmed T-cell lymphoma of gamma-delta subtype. Management with the CODOX-M/IVAC polychemotherapy regimen achieved rapid response including resolution of intraocular changes and substantial improvement of visual acuity to right 6/7.5, left 6/6. However, he relapsed before planned stem cell transplantation. Salvage with the gemcitabine/dexamethasone/cisplatin regimen, although temporarily effective, was followed by further relapse including widespread brain involvement, and he succumbed 10 months after presentation

    BackgroundLymphomas of the lacrimal sac are rare, accounting for less than 10% of lacrimal sac malignant tumours. They may present with symptoms typical of secondary acquired nasolacrimal duct obstruction and are thus often misdiagnosed.MethodsCase series and literature review.ResultsHerein we describe 3 cases of chronic lymphocytic leukaemia (CLL)/small-cell lymphocytic lymphoma (SLL) of the lacrimal sac with immunohistochemical and in 1 case molecular confirmation.ConclusionLymphomas of the lacrimal sac should be suspected in patients with known CLL presenting with epiphora and dacryocystitis. During dacryocystorhinostomy, an incisional biopsy of the lacrimal sac is essential for confirming CLL/SLL involvement and may guide treatment

    BACKGROUND To report a case of metastatic hepatocholangiocarcinoma to the vitreous and retina. CASE PRESENTATION A 70-year-old male, who was recently diagnosed with hepatocholangiocarcinoma, was complaining of floaters in his right eye over the past 5 months and was referred to the Liverpool Ocular Oncology Centre. On presentation, his visual acuity in the right eye was 6/24. Fundus exam revealed a whitish, unilateral, full-thickness retinal lesion at the inferotemporal arcade of his right eye, with vitreous infiltration and subretinal fluid. The patient underwent 25G pars plana vitrectomy with biopsy, resection of the lesion and intravitreal bevacizumab injection. Histopathology testing of the surgical specimens confirmed the diagnosis of metastatic carcinoma to the eye. Two months postoperatively his visual acuity had improved to 6/7.5 and there was no sign of active disease in his right eye, while 9 months postoperatively his visual acuity decreased to 6/9.5 due to developing nuclear sclerotic cataract in his right eye. CONCLUSION The current report presents the first case of a hepatocholangiocarcinoma metastasis to the vitreous and retina

    RESUMO: Objectivo: Realizar a medida da área vascular tumoral e a contagem individual dos microvasos, demonstrados por imuno-histoquímica, em imagens de campos microscópicos de carcinoma de células não pequenas dos pulmões, verificando a correlação dessas medidas com a sobrevida dos pacientes. Tipo do estudo: transversal e observacional. Material e métodos: O material foi proveniente de peças cirúrgicas de 107 pacientes com carcinoma de células não pequenas dos pulmões tratados no Pavilhão Pereira Filho â Santa Casa de Porto Alegre. A partir de cortes de tecido incluídos em parafina, foi realizada imuno-histoquímica com o anticorpo monoclonal anti-CD 34 (clone QB-End10; DAKO Corporation). A área vascular tumoral e a contagem de microvasos foram obtidas com o auxílio do programa de computador Image Pro Plus â 3.0. Resultados: A sobrevida média, em cinco anos, nos casos com alta área vascular (utilizando a média das áreas como ponto de corte) foi 21,7 meses±2,5, sendo significativamente menor (P < 0,0001) do que os de baixa área vascular, com 38,9 meses±3,0. O coeficiente de correlação entre a medida de área de microvasos e a contagem numérica destes foi 0,5 (P = = 0,001). A área vascular tumoral apresentou maior correlação com a sobrevida (coef. correlação â 0,48/P=0,001) do que a contagem numérica dos microvasos tumorais (coef. de correlação â 0,2 / P=0,03). Não foi encontrada correlação significativa entre a medida de área de microvasos e classificação histológica do tumor, sistema TNM, estado linfonodal e estadiamento clínico. Conclusão: A medida de área vascular tumoral, estabelecida com auxílio de computador, pode ser utilizada como um factor prognóstico para o carcinoma de células não pequenas dos pulmões.REV PORT PNEUMOL IX (1): 19-32 ABSTRACT: Objective: To accomplish the tumor vascular area measure and the microvessel count, shown by immunohistochemistry, in non small cell lung cancer (NSCLC) microscopic images, and verify the correlation between these measurements and patients survival. Design: cross-sectional and observational. Material and methods: The material was deriving from 107 NSCLC surgical specimens in Pavilhão Pereira Filho â Santa Casa, Porto Alegre. Immunohistochemistry with anti-CD 34 monoclonal antibody (QB-End10; DAKO Corporation) was performed on paraffin-embedded tissue sections. The tumoral vascular area and the microvessel count were obtained by Image Pro Plus â 3.0 program. Results: The 5-year survival rate of high vascular area group (the cut-off was the mean of areas) was 21.7 months±2.5, significantly lower (P < 0.0001) than the low vascular area cases, 38.9 months±3.0. The correlation coefficient between microvessel area and microvessel count was 0.5 (P=0.001). The tumoral vascular area shown higher correlation to survival (correlation coefficient: â0.48 / P=0.001) than the tumoral microvessel count (correlation coefficient: â0.2 / P=0.03). There was not any significant correlation between the microvessel areas and the histological type, the TNM, the lymph nodes status and the clinical staging. Conclusion: The tumoral vascular area measurement, with computed assistance, can be used as a prognostic marker in NSCLC.REV PORT PNEUMOL IX (1): 19-32 Palavras-chave: Angiogénese, CD 34, Imuno-histoquímica, Carcinoma de células não pequenas dos pulmões, Análise de imagem, Key-words: Angiogenesis, CD 34, Immunohistochemistry, NSCLC, Image analysi

    OBJETIVO: Correlacionar os achados citológicos da biópsia aspirativa com agulha fina (BAAF) de lesões intra-oculares suspeitas de malignidade com a histopatologia obtida quando o tratamento de escolha foi enucleação ou ressecção da lesão tumoral. MÉTODOS: Análise retrospectiva de 51 pacientes submetidos à biópsia aspirativa com agulha fina com fins diagnósticos ou para correlação cito-histológica. Foram excluídos os casos com lesões não sólidas, tratamento conservador e biópsias guiadas por ultra-som. Após exclusões, 20 olhos de pacientes contendo lesões intra-oculares suspeitas de malignidade foram estudados, sendo 12 do sexo feminino, com idades entre 2 e 78 anos. Todas biópsias foram realizadas pela primeira autora sob observação direta (microscópio) ou indireta (oftalmoscopia binocular indireta). A rota escolhida foi transaquosa para os tumores de segmento anterior e transvítrea com acesso escleral para os tumores de segmento posterior, exceto os casos suspeitos de retinoblastoma, biopsiados com acesso pela periferia da córnea. Foram obtidas 2 amostras de áreas diferentes do tumor em todos os casos com agulha calibre 25. As amostras colhidas foram encaminhadas para processamento, fixação e coloração pelo método de Papanicolaou e hematoxilina-eosina. Os espécimens obtidos para histopatologia foram corados pela hematoxilina-eosina. RESULTADOS: Três casos eram tumores de segmento anterior (íris) e 17 de segmento posterior, sendo 3 retinoblastomas. Nove pacientes foram submetidos à biópsia aspirativa com agulha fina com fins diagnósticos e 11 para correlação cito-histológica após enucleação. Somente dois casos apresentaram quantidade insuficiente de material para diagnóstico e posteriormente revelaram ser um granuloma e um melanoma maligno de coróide. CONCLUSÕES: A biópsia aspirativa com agulha fina parece ser um método diagnóstico confiável baseado na correlação cito-histológica neste grupo de pacientes.<br>PURPOSE: To correlate the cytologic findings of fine-needle aspiration biopsy (FNAB) of intraocular tumors with the histopathology specimen when enucleation or tumor resection was the treatment of choice. METHODS: Retrospective analysis of 51 patientssubmitted tofine-needle aspiration biopsy for diagnostic purposes or cyto-histologic correlation. Exclusion criteria were non-solid lesions, conservative treatment and ultrasound guided biopsies. After exclusions, 20 patients with intraocular solid lesions suspected to be malignant were studied, 12 of them were females, with ages between 2 and 78 years. All biopsies were performed by the first author under direct (operating microscope) or indirect (binocular indirect ophthalmoscope) visualization. The chosen route was transaqueous for anterior segment tumors and transvitreous through the sclera for posterior segment tumors except cases with suspicion of retinoblastoma biopsied through the peripheral cornea. Two samples were obtained from different areas of the tumor, in all cases with a 25-gauge needle. After fine-needle aspiration biopsy, samples were sent for processing, fixation, and staining with the Papanicolaou and hematoxylin-eosin (HE) methods. Histology specimens were stained with hematoxylin-eosin. RESULTS: Three cases consisted of anterior segment (iris) tumors and 17 of tumors situated in the posterior segment, 3 of them retinoblastomas. Nine patients were biopsied for diagnostic purposes and 11 for cytological-histological correlation after enucleation. In only two cases, fine-needle aspiration biopsy yielded insufficient material for diagnosis that subsequently proved to be a granuloma and a melanoma. CONCLUSIONS: Fine-needle aspiration biopsy seems to be a reliable procedure based on cytological-histological correlations in the studied group

    OBJETIVO: Relatar o caso de um paciente com carcinoma de pulmão cuja primeira metástase detectada foi em coróide e a abordagem diagnóstica deste caso. MÉTODOS: Um homem de 35 anos, em tratamento devido a uma condensação pulmonar isolada, referiu baixa da acuidade visual súbita, dor, secreção e olho vermelho (olho direito) há 10 dias. Ao exame oftalmológico foi detectada a presença de descolamento não regmatogênico de retina e múltiplos focos tumorais em coróide confirmado pela ultra-sonografia ocular diagnóstica. Foi sugerida biópsia aspirativa com agulha fina (BAAF) para diagnosticar possível doença metastática. A biópsia aspirativa com agulha fina foi realizada sob anestesia peribulbar e sedação. A rota escolhida foi transvítrea através de esclerotomia a 4 mm do limbo. O procedimento foi monitorado via oftalmoscopia binocular indireta. Foram obtidas 2 amostras de focos tumorais diferentes. Após a biópsia aspirativa com agulha fina, as amostras foram encaminhadas para processamento, fixação e coloração pelos métodos Papanicolaou e hematoxilina-eosina. RESULTADOS: A citologia confirmou a suspeita de múltiplos focos metastáticos coroídeos. Os aspirados ocular e pulmonar revelaram ser de mesma origem devido à reação positiva com pan-citoqueratina (AE1/AE3). O paciente evoluiu para óbito 4 meses após diagnóstico citológico de carcinoma metastático ocular. CONCLUSÕES: A biópsia aspirativa com agulha fina foi eficiente em diagnosticar e correlacionar a citologia ocular com o tumor primário por métodos citoquímicos neste caso. A biópsia aspirativa com agulha fina ainda deve ser usada em casos selecionados e pesquisas futuras serão necessárias para que este procedimento diagnóstico seja considerado padrão em oftalmologia.<br>PURPOSE: To report a case of a patient with lung carcinoma in which the first detected metastasis was to the choroid, how it was diagnosed and confirmed. METHODS: A 35 year-old white male, while being treated for a solitary pulmonary condensation, reported sudden loss of vision, pain, discharge and red eye (right eye) for 10 days. During the ophthalmic examination a nonregmatogenous retinal detachment as well as multiple choroidal tumors were confirmed by diagnostic ocular ultrasound. Fine-needle aspiration biopsy (FNAB) was suggested to diagnose a possible metastatic disease. Fine-needle aspiration biopsy was performed under peribulbar anesthesia with sedation. A transvitreous route was chosen through a sclerotomy 4 mm from the limbus. The procedure was monitored via binocular indirect ophthalmoscopy. Two sample aspirates were obtained from different tumour foci. After fine-needle aspiration biopsy, the aspirates were sent for processing, fixation and stained with Papanicolaou and HE. RESULTS: Cytology confirmed the diagnosis of multiple metastatic tumors. Immunocytochemistry of ocular and lung aspirates revealed a common cell origin by a pankeratin (AE1/AE3) positive test. Regardless of systemic treatment with chemotherapy and improvement of the ocular status, the patient died 4 months after cytological diagnosis of metastatic carcinoma of the choroid. CONCLUSIONS: Fine-needle aspiration biopsy was efficient to diagnose and correlate ocular cytology with the primary tumor by imunohistochemical methods in this case. Fine-needle aspiration biopsy should still be used only in selected cases and further research will be necessary for it to become a standard diagnostic procedure in ophthalmology
