Primary basal cell carcinoma of the caruncle: case report and review of the literature

ABSTRACT We present a rare case of primary caruncle basal cell carcinoma (BCC), a condition with limited occurrences. Our patient, an 80-year-old woman without prior ocular pathological history, presented a 2x2mm pedunculated blackish nodular lesion on the caruncle of her left eye, without local conjunctival or cutaneous involvement. Histological analysis following complete excision confirmed the presence of basal cell carcinoma within the caruncle. Over a span of 30 months, no recurrence has been observed. While scant cases are documented in the literature, we conducted a review of these instances. Despite its infrequent manifestation, this condition should be taken into account when evaluating caruncular tumors, given its tendency to invade the orbit. Complete excision with free surgical margins is the treatment of choice, and adjuvant radiotherapy or chemotherapy might be considered.

Quantitative Diffusion-Weighted MR Imaging: Is There a Prognostic Role in Noninvasively Predicting the Histopathologic Type of Uveal Melanomas?

Histopathologically, uveal melanomas (UMs) can be classified as spindle cell, mixed cell and epithelioid cell type, with the latter having a more severe prognosis. The aim of our study was to assess the correlation between the apparent diffusion coefficient (ADC) and the histologic type of UMs in order to verify the role of diffusion-weighted magnetic resonance imaging (DWI) as a noninvasive prognostic marker. A total of 26 patients with UMs who had undergone MRI and subsequent primary enucleation were retrospectively selected. The ADC of the tumor was compared with the histologic type. The data were compared using both one-way analysis of variance (ANOVA) (assessing the three histologic types separately) and the independent t-test (dichotomizing histologic subtypes as epithelioid versus non-epithelioid). Histologic type was present as follows: the epithelioid cell was n = 4, and the spindle cell was n = 11, the mixed cell type was n = 11. The mean ADC was 1.06 ± 0.24 × 10-3 mm2/s in the epithelioid cells, 0.98 ± 0.19 × 10-3 mm2/s in the spindle cells and 0.96 ± 0.26 × 10-3 mm2/s in the mixed cell type. No significant difference in the mean ADC value of the histopathologic subtypes was found, either when assessing the three histologic types separately (p = 0.76) or after dichotomizing the histologic subtypes as epithelioid and non-epithelioid (p = 0.82). DWI-ADC is not accurate enough to distinguish histologic types of UMs.

Comparative analysis of ultrasonic elastosonography and contrast-enhanced ultrasonography in the diagnosis of benign and malignant intraocular tumors.

PURPOSE: To compare the diagnostic value of ultrasonic elastosonography (UE) and contrast-enhanced ultrasonography (CEUS) for benign and malignant intraocular tumors. METHODS: This retrospective study enrolled patients with intraocular tumors at Beijing Tongren Hospital, Capital Medical University (August 2016 to January 2020). The strain rate ratio (strain rate of tumor tissue divided by strain rate of surrounding normal tissue) was measured by UE. CEUS was performed using SonoVue® contrast agent. The performance of each method at differentiating benign from malignant intraocular tumors was evaluated by receiver operating characteristic curve analysis. RESULTS: The analysis included 147 eyes in 145 patients (45.6 ± 13.4 years-old; 66 males): 117 patients (119 eyes) with malignant tumors and 28 patients (28 eyes) with benign tumors. At an optimal cutoff of 22.67 for the strain rate ratio, UE distinguished benign from malignant tumors with a sensitivity of 86.6% and a specificity of 96.4%. CEUS showed that 117 eyes with malignant tumors had a fast-in, fast-out time-intensity curve, and only two eyes with malignant tumors had a fast-in, slow-out curve, while all 28 eyes with benign tumors had a fast-in, slow-out curve. CEUS differentiated benign from malignant tumors with a sensitivity of 98.3% and a specificity of 100%. The diagnostic results differed significantly between the two methods (P = 0.004, McNemar test). The diagnostic performances of the two tests were moderately consistent (κ = 0.657, P < 0.001). CONCLUSION: Both CEUS and UE have good diagnostic value in the differentiation of benign intraocular tumors from malignant intraocular tumors.

Masquerade syndrome in ocular surface squamous neoplasia / Síndrome mascarada em neoplasia escamosa da superfície ocular

ABSTRACT The aim of this study was to alert the ophthalmic community to an atypical manifestation of ocular surface squamous neoplasia, which may delay diagnosis and treatment and result in a guarded visual prognosis and significant sequelae. A 61-year-old immunocompetent man presented with an initial diagnosis of necrotizing scleritis in the right eye for 3 months. He was treated with systemic prednisone but experienced persistent pain and low visual acuity. Conjunctival biopsy of the affected region confirmed the diagnosis of invasive ocular surface squamous neoplasia, which progressed with intraocular and orbital invasion; thus, exenteration was performed. Masquerade syndrome should be suspected in patients with nodulo-ulcerative lesions of the conjunctiva and sclera. This clinical can be more aggressive, with a greater likelihood of intraocular and orbital involvement. The earlier the diagnosis and treatment, the better the patient prognosis.

RESUMO O objetivo é alertar a comunidade oftalmológica sobre uma manifestação atípica de neoplasia escamosa da superfície ocular (OSSN) que pode levar a um atraso no diagnóstico e tratamento, evoluindo com prognóstico reservado e significativas sequelas. Homem, imunocompetente, 61 anos com diagnóstico inicial de esclerite necrosante em olho direito há 3 meses, em tratamento com prednisona sistêmica porém com persistência da dor e baixa acuidade visual. Realizado biópsia conjuntival em região acometida e diagnosticado como neoplasia escamosa da superfície ocular invasiva. Evolui com invasão intraocular e orbital sendo submetido a exenteração. Assim sendo, deve-se suspeitar de síndrome mascarada frente a um paciente com lesões nódulo-ulcerativas da conjuntiva e esclera. Essa forma clínica pode ser mais agressiva, com maior chance de comprometimento intraocular e orbital. Quanto mais precoces o diagnóstico e o tratamento, melhor o prognóstico para o paciente.

Analysis of ocular surface and quality of life in patients with corneal and conjunctival tumors / Análise da superfície ocular e qualidade de vida em pacientes com tumores córneo-conjuntivais

ABSTRACT Purpose: To evaluate the impact of corneal and conjunctival tumors on the ocular surface and quality of life of patients before and after surgical treatment. Methods: This prospective study conducted a preoperative and 30- and 90-day postoperative assessment of patients diagnosed with conjunctival and corneal tumors. Demographic data were collected preoperatively. The 12-Item Short-Form Health Survey (SF-12) and Ocular Surface Disease Index (OSDI) questionnaires were applied to assess patients' quality of life and perception of their vision-related functions. The tear breakup time and Schirmer tests were performed for ocular surface evaluation. The tumor extensions were measured using ImageJ image analysis software. Results: Twenty-three patients were enrolled. The mean age at examination was 52.8 ± 17.3 years (range: 27-9 years). The most common tumor type was squamous cell carcinoma (61.5%). The patients' visual acuity improved significantly at 1 month and 3 months (p=0.018 and p=0.036, respectively). No significant differences were found between tear breakup time and Schirmer tests preoperatively and at 3 months postoperatively (p=0.150 and p=0.490, respectively). The SF-12 scores demonstrated significant differences between the preoperative and 30- and 90-day postoperative mental components (p=0.008 and p=0.026, respectively). Tumor extension was 868.7 ± 344.9 pixels (range, 224.6-1481.6 pixels) and were significantly correlated with the preoperative (p=0.011), 30-day postoperative (p=0.017), and 90-day postoperative (p=0.012) SF-12 mental components, as well as the emotional component at the 30th postoperative day (p=0.016). Conclusion: Patients with corneal and conjunctival tumors improved their ocular symptoms, visual acuity, and the emotional component of their quality of life after surgical excision of the tumor.

RESUMO Objetivo: Avaliar o impacto dos tumores cór­neo-conjuntivais na superfície ocular e na qualidade de vida dos pacientes antes e após o tratamento cirúrgico. Métodos: Este estudo prospectivo conduziu uma avaliação pré-operatória e com 30 e 90 dias de pós-operatório de pacientes com diagnóstico de tumores de córnea e conjuntiva. Os dados demográficos foram coletados no pré-operatório. Os questionários Health Survey Short-Form (SF-12) e Ocular Surface Disease Index (OSDI) foram aplicados para avaliar a qualidade de vida dos pacientes e a percepção de suas funções relacionadas à visão. Os testes tear break-up time (TBUT) e Schirmer foram realizados para avaliação da superfície ocular. A extensão do tumor foi medida usando o programa ImageJ. Resultados: Vinte e três pacientes foram incluídos. A média de idade foi de 52,8 ± 17,3 anos (27-79 anos). O tipo mais comum de tumor foi o carcinoma de células escamosas (61,5%). A acuidade visual dos pacientes melhorou significativamente em 1 mês e 3 meses (p=0,018 e p=0,036, respectivamente). Não houve diferenças significativas entre os testes tear break-up time e Schirmer no pré-operatório e com 3 meses de pós-operatório (p=0,150 e p=0,490, respectivamente). Os escores do SF-12 demonstraram que o componente mental apresentou diferença estatisticamente significante entre o pré-operatório e no 30 e 90 dias de pós-operatório (p=0,008 e p=0,026, respectivamente). A extensão do tumor foi de 868,7 ± 344,9 pixels (intervalo, 224,6-1481,6 pixels) e foram significativamente correlacionados com o componente mental de SF-12 no pré-operatório (p=0,011), 30 (p=0,017) e 90 dias de pós-operatório (p=0,012), e o componente emocional no 30º dia de pós-operatório (p=0,016). Conclusão: Pacientes com tumores córneo-conjuntivais melhoraram os sintomas oculares, a acuidade visual e o componente emocional da qualidade de vida após a excisão cirúrgica do tumor.

Metástase iridociliar presumida de carcinoma mamário: relato de caso / Presumed iridociliary metastasis of breast carcinoma: case report

RESUMO A metástase ocular é uma patologia incomum, principalmente quando se considera a íris como sítio da metástase. Apesar de incomum, a metástase ocular possui o câncer de mama como um de seus principais sítios primários. Ocasionalmente, a manifestação oftalmológica pode ser primária a qualquer outra clínica. Este artigo relata o caso de uma paciente com carcinoma de mama ductal invasivo com presumida metástase em corpo ciliar e íris em olho direito. O diagnóstico precoce interfere de forma significativa na evolução do quadro, sendo necessário o acompanhamento oftalmológico.

ABSTRACT Ocular metastasis is an uncommon pathology, especially when considering the iris as the site of metastasis. Although uncommon, eye metastasis has breast cancer as one of its main primary sites. Occasionally, the ophthalmologic manifestation may be primary to any other clinical manifestation. This article reports the case of a patient with invasive ductal breast carcinoma with presumed metastasis in the ciliary body and iris in the right eye. Early diagnosis significantly affects the evolution of the condition, requiring ophthalmologic follow-up.

Choroidal melanoma tumor profile and treatment pattern for newly diagnosed patients at a reference public hospital in Sao Paulo, Brazil.

BACKGROUND: Choroid, ciliary body, and iris melanomas are often grouped as uveal melanoma, the most common intraocular primary malignancy. The purpose of the current study was to analyze the tumor profile of newly diagnosed cases of choroidal melanoma at a reference center in Sao Paulo, Brazil, and to investigate the frequency of eyes treated by enucleation that could have been treated with brachytherapy if available in the service. METHODS: Medical records of patients referred to our service with initial diagnostic hypothesis of choroidal melanoma from July 2014 to June 2020 were analysed on demographics, diagnosis confirmation, tumor measurement by ultrasonography and established treatment. Data were evaluated on clinical and demographic characteristics as age, sex, affected eye, ultrasound parameters, and treatment management of patients with clinically diagnosed choroidal melanoma. Among the patients submitted to enucleation, we investigated how many could have been selected to receive brachytherapy. RESULTS: From the 102 patients referred with the choroidal melanoma diagnosis hypothesis, 70 (68.62%) were confirmed. Mean measurements from the tumors in millimetres were: 9.19 ± 3.69 at height and 12.97 ± 3.09 by 13.30 ± 3.30 at basal. A total of 48 cases (68.57%) were enucleated, 8 (11.43%) were treated by brachytherapy in a different service, and 14 patients (20.00%) returned for enucleation at their original referral center. Out of the 48 patients enucleated, 26 (54.17%) could have been selected to brachytherapy treatment. CONCLUSIONS: The results indicate a late diagnosis of choroidal melanoma cases referred to our service. Most enucleated cases could have been treated with brachytherapy if it was broadly available at the national public health insurance. Further public health political efforts should focus on early diagnosis and better quality of life post-treatment for oncologic patients.

[Imaging of retinoblastoma : Current state-of-the-art and future prospects]. / Bildgebung des Retinoblastoms : Aktueller Stand der Technik und Ausblick in die Zukunft.

BACKGROUND: Retinoblastoma is the most common malignant eye tumor in children and is associated with tumor predisposition syndrome (RB1 mutation) in up to 40% of cases. Imaging is an important part of the diagnostic workup of children with retinoblastoma both during the initial diagnosis and follow-up. OBJECTIVES: The goal of this review is to present the current state-of-the-art regarding imaging of children with retinoblastoma, including technical background and diagnostic clues with a brief discussion of future prospects. In addition, we summarize the general clinical diagnostic workup and therapeutic options. MATERIALS AND METHODS: Review of the literature and our own experience in the imaging of retinoblastoma. CONCLUSION: High-resolution magnetic resonance imaging (MRI) is the imaging modality of choice in children with retinoblastoma for diagnosis (estimation of diagnosis/differential diagnosis, evaluation of local and intracranial tumor extension) and during follow-up. Despite the characteristic calcifications, computed tomography (CT) examinations are no longer indicated in these patients. Due to the high association with tumor predisposition syndrome, genetic counselling is recommended.

Sociodemographic, clinical, epidemiological and care aspects of children and adolescents treated for retinoblastoma in Brazil: a cross-sectional study / Aspectos sociodemográficos, clínicos, epidemiológicos e assistenciais de crianças e adolescentes atendidos por retinoblastoma no Brasil: estudo transversal

Introduction: Retinoblastoma greatly impacts the affected children and adolescents and their families. Epidemiological approaches to this form of cancer in Brazil are scarce, and this gap motivated this study. Objectives:This study aimed to describe the sociodemographic, clinical, epidemiological, and care characteristics of children and adolescents treated for retinoblastoma in Brazil and analyze whether there is any association between them. Methods: It is a cross-sectional, descriptive-analytical study, carried out with accompanying family members of children and adolescents treated for retinoblastoma in Brazil, sampled by snowball sampling, via a web survey, based on a semi-structured questionnaire elaborated by the authors, shared on social media. Results: The children and adolescents were represented by 129 accompanying family members from the five largest regions of Brazil. Low education level, housewifery, and low family income were associated with exclusive care provided by the Unified Health System, while low family income was associated with the use of ocular prosthesis post retinoblastoma. Conclusion: The identified odds ratio indicated the importance of family members' sociodemographic aspects for the clinical, epidemiological and care outcomes of the children and adolescents treated. Public healthcare services were the most used for oncology care, which endorses the relevance of the Unified Health System for children, adolescents, and their family members who have been impacted by retinoblastoma in the country (AU)

Introdução: O retinoblastoma impacta sobremaneira as crianças, adolescentes e familiares acometidos. Abordagens epidemiológicas sobre tal câncer no Brasil são escassas, lacuna esta que motivou este trabalho. Objetivos: Os objetivos desse estudo foram descrever as características sociodemográficas, clínicas, epidemiológicas e assistenciais de crianças e adolescentes atendidos por retinoblastoma no Brasil e analisar se existe associação entre tais características. Métodos: Tratou-se de um estudo transversal, descritivo-analítico, realizado com acompanhantes familiares de crianças e adolescentes atendidos por retinoblastoma no Brasil, amostrados por snowball sampling, via web survey, a partir de um roteiro autoral semiestruturado, compartilhado em mídias sociais. Os dados foram analisados por meio de estatística descritiva e inferencial, com o auxílio do software Statistical Package for the Social Sciences. Resultados: As crianças e os adolescentes foram retratados por 129 acompanhantes familiares das cinco grandes regiões brasileiras. A escolaridade baixa, a ocupação do lar e a baixa renda familiar dos respondentes associaram-se ao atendimento exclusivo pelo Sistema Único de Saúde, sendo que a baixa renda familiar também associou-se ao uso de prótese ocular pós retinoblastoma. Conclusões: As razões de chances identificadas sinalizaram para a importância dos aspectos sociodemográficos dos familiares para os desfechos clínicos-epidemiológicos-assistenciais das crianças e dos adolescentes atendidos. Os serviços públicos foram os mais utilizados para a assistência oncológica, o que endossa a relevância do Sistema Único de Saúde para as crianças, adolescentes e familiares impactados pelo retinoblastoma no país (AU)

Hidden in the Eyes-Recurrence of Systemic Hemopathies Reportedly "In Remission": Six Cases and Review of Literature.

Background and Objectives: Secondary ocular localizations of hematological malignancies are blinding conditions with a poor prognosis, and often result in a delay in the diagnosis. Materials and Methods: We describe a series of rare cases of ocular involvement in six patients with hematological malignancies, reportedly in remission, who presented secondary ocular localizations, challenging to diagnose. Two patients had an acute lymphoblastic leukemia (ALL) and developed either a posterior scleritis or a pseudo-panuveitis with ciliary process infiltration. One patient had iris plasmacytoma and developed an anterior uveitis as a secondary presentation. Two patients had a current systemic diffuse large B-cell lymphoma (DLBCL) and were referred either for intermediate uveitis or for papilledema and vitritis with secondary retinitis. Finally, one patient with an acute myeloid leukemia (AML) presented a conjunctival localization of a myeloid sarcoma. We herein summarize the current knowledge of ophthalmologic manifestations of extramedullary hematopathies. Results: Inflammatory signs were associated with symptomatic infiltrative lesions well displayed in either the iris, the retina, the choroid, or the cavernous sinus, from the admission of the patients in the ophthalmological department. These findings suggest that patients with ALL, AML, systemic DLBCL, and myeloma can present with ophthalmic involvement, even after having been reported as in remission following an effective systemic treatment and/or allograft. Conclusions: Early detection of hidden recurrence in the eyes may permit effective treatment. Furthermore, oncologists and ophthalmologists should be aware of those rare ocular malignant locations when monitoring patient's progression after initial treatment, and close ophthalmologic examinations should be recommended when detecting patient's ocular symptoms after treatment.

Histopathologic and MR Imaging Appearance of Spontaneous and Radiation-Induced Necrosis in Uveal Melanomas: Initial Results.

Necrosis in uveal melanomas can be spontaneous or induced by radiotherapy. The purpose of our study was to compare the histopathologic and MRI findings of radiation-induced necrosis of a group of proton beam-irradiated uveal melanomas with those of spontaneous necrosis of a control group of patients undergoing primary enucleation. 11 uveal melanomas who had undergone proton beam radiotherapy, MRI and secondary enucleation, and a control group of 15 untreated uveal melanomas who had undergone MRI and primary enucleation were retrospectively identified. Within the irradiated and nonirradiated group, 7 and 6 eyes with histological evidence of necrosis respectively, were furtherly selected for the final analysis; the appearance of necrosis was assessed at histopathologic examination and MRI. Irradiated melanomas showed a higher degree of necrosis as compared with nonirradiated tumors. Irradiated and nonirradiated lesions differed based on the appearance and distribution of necrosis. Irradiated tumors showed large necrotic foci, sharply demarcated from the viable neoplastic tissue; nonirradiated tumors demonstrated small, distinct foci of necrosis. Radiation-induced necrosis, more pigmented than surrounding viable tumor, displayed high signal intensity on T1-weighted and low signal intensity on T2-weighted images. The hemorrhagic/coagulative necrosis, more prevalent in nonirradiated tumors (4 out of 6 vs. 1 out of 7 cases), appeared hyperintense on T2-weighted and hypointense on T1-weighted images. Our study boosts the capability to recognize radiation-induced alterations in uveal melanomas at MRI and may improve the accuracy of radiologists in the evaluation of follow-up MR examination after radiotherapy.

Differentiation of lacrimal gland tumors using the multi-model MRI: classification and regression tree (CART)-based analysis.

BACKGROUND: Little is known about the value of dynamic contrast-enhanced (DCE) in combination with diffusion-weighted imaging (DWI) for the differentiation of lacrimal gland tumors. PURPOSE: To evaluate the ability of DCE and DWI in differentiating lacrimal gland tumors. MATERIAL AND METHODS: DCE and DWI were performed in 72 patients with lacrimal gland tumors. Time-intensity curve (TIC) patterns were categorized as type A, type B, type C, and type D. Apparent diffusion coefficient (ADC) was measured on DWI. Then, the diagnostic effectiveness of TIC in conjunction with ADC was assessed using classification and regression tree (CART) analysis. RESULTS: Type A tumors were all epithelial; they could be further separated into pleomorphic adenoma sand carcinomas. Type B tumors were all non-epithelial tumors, which could be further separated into benign inflammatory infiltrates (BIIs) and lymphomas. Type C tumors contained both carcinomas and non-epithelial tumors, which could be diagnosed into carcinomas, BIIs and lymphomas. Type D tumors were all PAs. The mean ADC of epithelial tumors was significantly higher than that of non-epithelial tumors, and the mean ADC values were significantly different between PAs and carcinomas. Besides, the mean ADC value of BIIs was higher than that of lymphomas. Therefore, the CART decision tree made by ADC and TIC had a predictive accuracy of 86.1%, differentiating lacrimal gland tumors effectively. CONCLUSION: Combined DCE and DWI-MRI can efficiently differentiate lacrimal gland tumors which can be of help to ophthalmologists in the diagnosis and treatment of these tumors.

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.

Chronic unilateral tearing as a sign of lacrimal sac squamous cell carcinoma / Lacrimejamento unilateral crônico como sinal de Carcinoma espinocelular de saco lacrimal

ABSTRACT Tearing is a very common symptom in ophthalmic practice; however, this issue is commonly overlooked. The authors describe the case of a patient with chronic unilateral epiphora that had been neglected for 8 y; lacrimal system workup was performed for this patient only because of dacryocystitis evolvement. Following the diagnosis of nasolacrimal duct blockage, dacryocystorhinostomy was indicated. Intraoperative abnormal mucosa was subjected to biopsy, and a diagnosis of squamous cell carcinoma in the lacrimal sac was established. Extended tumor excision was performed for the patient and adjuvant radiotherapy was administered, without any recurrence till the 2-year follow-up. The present report highlights the relevance of a detailed evaluation for determining the underlying causes of tearing, especially in chronic unilateral presentation. The consideration of potential malignancy in such cases could prevent delayed diagnosis of uncommon but potentially life-threatening malignancies of the lacrimal drainage system.

RESUMO O lacrimejamento é um sinal comum na prática oftalmológica, porém frequentemente negligenciado. Os autores descrevem um caso de um paciente com epífora unilateral direita com 8 anos de história que só após evoluir com dacriocistite foi submetido a semiologia de vias lacrimais. Após o diagnóstico de obstrução baixa da via lacrimal foi submetido a cirurgia de dacriocistorrinostomia, onde o saco lacrimal de aparência atípica foi biopsiado e identificado como carcinoma espinocelular. O paciente foi submetido a ressecção oncológica do tumor seguido de radioterapia adjuvante, permanecendo livre de recidiva por 2 anos. Este caso ressalta a importância de investigar causas da epífora, especialmente quando unilateral, dada sua maior associação com a obstrução de via lacrimal. Uma semiologia oportuna das vias lacrimais podem evitar atrasos no diagnóstico de obstrução secundárias a neoplasia, que apesar de incomuns, são potencialmente fatais.

Lack of Association between Chlamydophila psittaci and Ocular Adnexal MALT Lymphoma in Korean Patients-Is the Geographic or Genetic Difference Significant?

Clamydophila psittaci (C. psittaci) has been proposed to be an etiologic factor in extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) in the ocular adnexa. However, the pathogenetical significance of the infection has not been fully elucidated. Many previous studies have shown controversial results regarding C. psittaci detection rates in said patients, ranging from 0 to 87%. We investigated the presence of C. psittaci in a single institutional cohort (n = 150) of ocular adnexal MALT lymphoma (OAML) patients in Korea. We tried to exclude the methodological biases derived from the different primer sets in polymerase chain reaction-based studies. For that reason, we applied five sets of primers, including four previously reported and one newly designed primer set. There was no case of C. psittaci-positive OAML in repeated trials validated with appropriate positive and negative controls. All 150 cases showed negative results with five primer sets. These results suggest that the pathogenetic role of C. psittaci in ocular adnexal MALT lymphoma might have been overestimated to date, at least in the Korean population. Therefore, the molecular diagnosis of C. psittaci is considered a very low priority.

Reconstrução após ressecção bipalpebral com preservação do globo ocular: desafio estético e funcional / Reconstruction after bipalpebral resection with preservation of the eyeball: aesthetic and functional challenge

Introdução: A reconstrução palpebral pode ser realizada por fechamento primário, enxerto de diferentes lamelas e retalhos locais e/ou regionais, únicos ou combinados. Essa reconstrução se torna mais complexa quando a pálpebra superior e a inferior são ressecadas em espessura total e o globo ocular é preservado. O objetivo é relatar as técnicas utilizadas para reconstrução periorbital em casos de ressecção bipalpebral (superior e inferior) com preservação do globo ocular pelo Grupo de Cirurgia Órbitopalpebral da Divisão de Cirurgia Plástica e Queimaduras do HCFMUSP. Métodos: Foram revistos todos os casos que se encaixaram nos critérios de inclusão no período de 2000 a 2019, sendo descritos dados epidemiológicos, cirúrgicos e de seguimento pós-operatório. Resultados: Apenas dois casos foram submetidos à exérese total do tecido periorbital e permaneceram passíveis de preservação do globo ocular. Ambos foram reconstruídos com retalhos frontais com oclusão total do globo ocular no primeiro momento, seguido pela liberação em etapas, mantendo o globo viável após a finalização da reconstrução. Discussão: São escassos os relatos semelhantes na literatura e, nestes casos, os resultados cirúrgicos se mostraram funcionalmente aceitáveis, mas com limitações estéticas importantes. Conclusão: Sugerimos uma nova opção para a reconstrução total da pálpebra superior e inferior (com um único retalho pedicular, desprovido de enxerto conjuntivo e em múltiplos estágios) que fornece proteção e conservação do globo ocular durante as diferentes etapas da cirurgia. Os resultados foram funcionalmente favoráveis, considerando a gravidade dos casos.

Introduction: Eyelid reconstruction can be performed by primary closure, a graft of different lamellae, and local and/or regional flaps, single or combined. This reconstruction becomes more complex when the upper and lower eyelids are resected to total thickness, and the eyeball is preserved. The objective is to report the techniques used for periorbital reconstruction in bipalpebral resection cases (upper and lower) with preservation of the eyeball by the Group of Orthopalpebral Surgery of the Division of Plastic Surgery and Burns of HCFMUSP. Methods: All cases that met the inclusion criteria from 2000 to 2019 were reviewed, and epidemiological, surgical, and postoperative follow-up data were described. Results: Only two cases were submitted to total exeresis of the periorbital tissue and remained susceptible to eyeball preservation. Both were reconstructed with frontal flaps with complete occlusion of the eyeball at the first moment, followed by the release in stages, keeping the globe viable after reconstruction completion. Discussion: Similar reports are scarce in the literature, and, in these cases, surgical results were functionally acceptable but with significant aesthetic limitations. Conclusion: We suggest a new option for total reconstruction of the upper and lower eyelid (with a single pedicular flap, devoid of connective graft and in multiple stages) that protects and conserves the eyeball during the various stages of surgery. The results were functionally favorable, considering the severity of the cases.
