目的：探讨眼部转移性透明细胞肾细胞癌(clear-cell renal cell carcinoma，CC-RCC)的临床病理特点。方法：选取复旦大学附属眼耳鼻喉科医院2010年1月至2020年12月收治的5例并经病理学检查证实的眼部转移性CC-RCC患者的临床病理资料，包括病史、临床表现、影像学检查、病理形态学特点、免疫表型及随访结果等，并进行回顾分析。结果：5例患者中3例为脉络膜转移性CC-RCC，均为男性，年龄51~62岁，均表现为右眼前黑影伴视力下降，病程为1~6个月，术前检查视力均为眼前手动，眼底见视网膜下隆起肿块伴视网膜脱离。B超显示球内隆起肿物，中等回声，考虑脉络膜黑色素瘤。其中例2在2年前有左侧肾CC-RCC切除病史，术后1年转移至肺。3例患者均行眼球摘除加义眼座植入术。病理学形态及免疫组织化学染色结果提示为球内恶性肿瘤，考虑转移性CC-RCC，建议在肾等处寻找原发灶。术后例1腹部CT检查发现左肾占位，考虑肾癌。胸部CT检查示两下肺多个转移瘤。例3术后PET-CT发现左肾占位，手术切除后证实为左肾CC-RCC。2例为眼眶转移性CC-RCC，例4为女性，56岁，右眼红肿伴眼球突出2个月，2个月前行右肾CC-RCC切除术，PEC-CT提示右侧眼眶转移伴骨质破坏。例5为男性，65岁，左眼眉弓处肿物3年，7年前行左肾癌摘除术，后肺部转移。所有5例患者手术切除标本病理学检查均示肿瘤细胞细胞质透明或颗粒状，呈实性片状和腺样分布，间质血管丰富，免疫组织化学表达CK、VIM、CD10和PAX-8等标记提示CC-RCC转移。结论：CC-RCC可以转移至脉络膜或眼眶，病理学上需要和其他眼部具有透明细胞特征的原发和转移性肿瘤相鉴别。
Objective: To evaluate the clinicopathological features of ocular metastatic clear-cell renal cell carcinoma.Methods: Data of 5 patients (5 eyes) with ocular metastatic clear-cell renal cell carcinoma treated and diagnosed at Eye & ENT Hospital of Fudan University from January 2010 to December 2020 were retrospectively analyzed for medical history, clinical features, imaging examinations, pathomorphological features, immunophenotypes and survival outcomes. Results: There were 3 males of choroidal metastatic clear-cell renal cell carcinoma with age from 51 to 62 years old. They all presented with shadow before the eye and reduced visual acuity of the right eye for 1 to 6 months. On examination the visual acuity was hand movement in front of the affected eye. Fundus examination showed a subretinal elevated mass with retinal detachment. B-scan ultrasound demonstrated an intraocular mass with medium internal reflectivity suspected of choroidal melanoma. Case 2 reported a history of clear-cell renal cell carcinoma treated with a left nephrectomy 2 years ago and developed lung metastasis 1 year ago. Three patients all underwent enucleation and prosthesis implantation. Histopathological and immunohistochemical examinations showed intraocular malignant tumor suggestive of clear-cell renal cell carcinoma which needed further examinations to confirm the primary tumor. Postoperative computed tomography scan of the abdomen for case 1 revealed a mass of the left kidney highly suggestive of a renal cell carcinoma. The computed tomography scan of the chest revealed multiple lesions suggestive of lung metastasis. Postoperative PET-CT scan of case 3 revealed a mass of the left kidney which was confirmed to be clear-cell renal cell carcinoma histopathologically. There were 2 patients of orbital metastatic clear-cell renal cell carcinoma. One 56-year-old female patient (Case 4) presented with swelling, redness and proptosis of the right eye for 2 months. Two months ago, her right kidney was resected for the diagnosis of clear-cell renal cell carcinoma. PEC-CT revealed metastasis to the right orbit with bone destruction. Another 65-year-old male patient (Case 5) presented with palpable mass of the left eyebrow for 3 years. He had left nephrectomy for renal cell carcinoma 7 years earlier and metastasis to the lung later. Histopathology of all 5 cases demonstrated uniform cells with clear or granular cytoplasm in solid and glandular arrangement surrounded by a rich vascular network. Immunohistochemical positivity for the biomarkers CK, Vimentin, CD10 and PAX-8 confirmed the diagnosis of metastatic clear-cell renal cell carcinoma.Conclusion: Clear-cell renal cell carcinoma can metastasize to the choroid or orbit. It should be differentiated from the other ocular primary and metastatic tumors with clear-cell appearance histopathologically.

Objective: To analyze the clinical characteristics and therapeutic effect of 46 patients with bilateral retinoblastoma(RB). Methods: The clinical data of 46 patients with bilateral retinoblastoma who received intravenous chemotherapy combined with transpupillary thermotherapy (TTT) or enucleation from December 2008 to December 2019 in our department were analyzed retrospectively. The eye salvage rate, enucleation rate, visual acuity, and chemotherapy side effects were evaluated. Results: The 46 enrolled patients were 27 males and 19 females, at an average age of (13.21±11.13) months at the first visit. Among them, 10 received chemotherapy, 11 received chemotherapy combined with TTT, 17 received chemotherapy combined with TTT and enucleation,and 2 received chemotherapy combined with freezing, 6 received chemotherapy combined with freezing and enucleation. After treatment, 58 eyes were salvaged, with a total salvage rate of 73.1% (57/78), and the eyes that preserved vision account for 64.1% (50/78). The eye salvage rate in each stage were 100.0% for stage A and B, 86.7% for stage C, and 94.1% for stage D, 35.7% for stage E. Twenty-four eyes were enucleated, with a total enucleation rate of 26.1% (24/92), and among 35 eyes at stage E, 21 eyes were enucleated, accounting for 60.0%(21/35). The average time of chemotherapy was 4.1±1.9 and the myelosuppressive effects of chemotherapy include leucopenia, thrombocytopenia and hemoglobinopenia. During the mean follow-up time of (35.4±23.8) months, 7 (15.2%) patients died, and 39 (84.8%) cases survived. The 5-year cumulative survival rate was 80.2%. Conclusion: Intravenous chemotherapy combined with local treatment has a good overall effect and plays an important role in the treatment of bilateral retinoblastoma. Intravenous chemotherapy leads to myelosuppression, and the myelosuppression gradually recovered after stopping intravenous chemotherapy.

Objective: To investigate the clinical, imaging and pathological features of orbital extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT), so as to reduce misdiagnosis and improve survival rate.Methods: The clinical, imaging and histopathological data of 71 patients with orbital extranodal marginal zone B cell lymphoma of MALT who were treated in Zhongshan Ophthalmic Center, Sun Yat-sen University from Jan.2020 to Dec. 2020 were retrospectively analyzed. Results: There were 38 males and 33 females in the 71 patients.There were 31 cases located on the left orbit, 34 cases on the right orbit, and 6 cases were bilateral; there were 67 primary cases and 4 relapsed cases. The age ranged from 23 to 84 years old. The disease course ranged from 3 months to 15 years. The main clinical manifestations included ocular masses and limited eyeball movement.Magnetic resonance imaging showed a “cast-like” soft tissue shadow of uniform density, and no intraocular invasion is observed. Histopathological examination showed that the tumor was composed of small to medium sized lymphocyte-like cells. Tumor cells exhibited diffuse or lamellar growth, with small to medium-sized irregular nuclei, and the nucleoli were inconspicuous. Some of the lymphocyte-like cells showed mononuclear lymphoma cells changes, and plasmacytoid differentiation was observed in 9 cases, in which kappa and lambda expressions were asymmetric.Conclusion: The clinical manifestations of orbital extranodal marginal zone B cell lymphoma of MALT are various, and imaging examination has certain characteristics, which can assist preoperative diagnosis.Pathological examination can be used for accurate diagnosis and classification after operation, based on which appropriate treatment plan can be made and curative effect can be improved.
黏膜相关淋巴组织(mucosa-associated lymphoid tissue lymphomas，MALT)淋巴瘤是原发性眼附属器淋巴瘤(primary ocular adnexal lymphoma，POAL)中最常见的病理类型。目前，原发性眼附属器黏膜相关淋巴组织淋巴瘤(primary ocular adnexal mucosa-associated lymphoid tissue lymphoma，POAML)的临床类型和临床表现尚未被眼科医师熟练掌握，临床治疗亦无共识和指南。本文根据POAML起源位置，重点介绍各临床类型的早中期临床表现，以及针对各临床类型和病变范围的个体化治疗方法。
Mucosa-associated lymphoid tissue lymphomas (MALT) lymphoma is the most common pathologic type in primary ocular adnexal lymphoma (POAL). Currently, the clinical types and manifestations of primary ocular adnexal mucosa-associated lymphoid tissue lymphoma (POAML) have not been well understood by ophthalmologists, and there is no consensus or guideline for clinical treatment. According to the original location, this paper focuses on the clinical manifestations of early and intermediate-stage POAML, as well as the individualized treatment for each clinical type and lesion range.
近年来日益强大的眼内液分子/细胞生物学检测技术因其简便、快捷和高效的特点，使得眼科医生在诊断眼内淋巴瘤时倾向于单纯只依据此类方法而淡化病理诊断的重要性。眼内液分子/细胞生物学技术因其本身只能“间接提示肿瘤细胞存在”的局限性而不能作为眼内淋巴瘤的确诊依据。眼内组织/细胞病理仍然是眼内淋巴瘤诊断的金标准，其价值和地位不能被其他任何分子/细胞生物学检测手段所替代。理解并掌握各种诊断、检测技术的优势和局限性，规范和优化眼内组织/细胞病理标本的采集、保存和送检流程有助于提高眼科临床医生对眼内淋巴瘤的诊断效率和医疗质量。
In recent years, more and more powerful molecular/cellular biological techniques of intraocular fluid have made ophthalmologists tend to only rely on these methods in the diagnosis of intraocular lymphoma because of their features of simplicity, fastness and efficiency. The molecular/cellular biological techniques of intraocular fluid cannot be used as the basis for the diagnosis of intraocular lymphoma because it can only indicate the existence of tumor cells indirectly. Intraocular tissue/cell pathology remains the gold standard for the diagnosis of intraocular lymphoma, and its importance cannot be replaced by any other molecular/cell biological methods. Understanding and mastering the advantages and limitations of various diagnostic techniques, standardizing and optimizing the collection, preservation and submission process of intraocular tissue/cell specimens will help ophthalmologists improve the diagnostic efficiency and medical quality of intraocular lymphoma.
眼附属器淋巴组织增生性疾病作为一类疾病的总称，包括了良性淋巴组织增生、非典型性淋巴组织增生、IgG4相关眼病以及多种恶性淋巴瘤在内的数十种疾病类型。临床诊断此类疾病应将患者眼部体征、影像学检查与病理学检查紧密结合。随着免疫表型及分子病理等检测技术的进步，此类疾病之间的鉴别诊断正逐渐清晰。本文就眼附属器淋巴组织增生性疾病进行系统性描述，并重点探讨该类疾病的病理鉴别诊断。
Ocular adnexal lymphoproliferative disease, as a general term, contains reactive lymphoid hyperplasia, atypical lymphoid hyperplasia, IgG4 related ocular disease and malignant lymphoma. The clinical diagnosis of this kind of disease should integrate patient’s symptoms, imaging features and pathology characteristics. Development of immunophenotyping, molecular pathology and other detection technology will help with the differential diagnosis of ocular adnexal lymphoproliferative disease. This article is going to discuss the etiology, epidemiology,diagnosis and treatment of ocular adnexal lymphoproliferative disease, with a focus on the clinicopathological differential diagnosis of such disease.
眼内淋巴瘤(intraocular lymphoma，IOL)比较罕见。按起源位置分为两种类型，主要类型为原发性眼内淋巴瘤(primary intraocular lymphoma，PIOL)，也称为原发性中枢神经系统淋巴瘤(primary central nervous system lymphoma，PCNSL)；另外一种类型为继发性眼内淋巴瘤(secondary intraocular lymphoma，SIOL)，为中枢神经系统以外的淋巴瘤转移至眼内。按肿瘤类型主要分为三类，主要类型为眼内弥漫大B细胞淋巴瘤，属于高级别淋巴瘤，预后较差；其次为少见的主要侵犯脉络膜的黏膜相关淋巴组织结外边缘区B细胞淋巴瘤，属于低级别淋巴瘤，预后较好；第三种类型为极少见的眼内NK/T细胞淋巴瘤，属于高级别淋巴瘤，预后极差。该病的诊断对眼科医生和病理医生都极具挑战性。实验室检测方法主要包括病理学、免疫细胞化学、流式细胞术、细胞因子及基因重排等，但眼内病理活检仍然是该病诊断的金标准。该病的治疗主要为眼内局部化疗、放射治疗及系统性化疗。IOL早期常因误诊而耽误治疗，目前该病明确诊断时多在患者出现症状后4~40个月，多数病例早期被误诊为葡萄膜炎而失去治疗的最佳时机，导致预后较差。因此应充分认识IOL的早期表现，早期诊断、早期治疗，从而大大提高疗效。
Intraocular lymphomas (IOL) are rare malignant neoplasms including primary intraocular lymphoma (PIOL) and secondary intraocular lymphoma (SIOL). The former is also known as primary central nervous system lymphoma(PCNSL). The latter is a kind of lymphoma metastasizing to the eye from outside the central nervous system. IOL can further be divided into three different types. The most common type is vitreoretinal high-grade diffuse large B-cell lymphoma with poor prognosis. The less common type is primary choroidal extranodal marginal zone B-cell lymphoma of mucosa associated lymphoid tissue, which is low-grade B-cell lymphoma with better prognosis.The rare type is NK/T cell lymphomas with very poor prognosis. The diagnosis of this disease is challenging for both ophthalmologists and pathologists. Laboratory testing methods mainly include cytology/pathology,immunocytochemistry, flow cytometry, cytokine analysis and gene rearrangement detection. The detection of malignant lymphoid cells cytologically/pathologically is still the gold standard for diagnosing IOL. The treatment involves local chemotherapy, radiotherapy and systemic chemotherapy. Most intraocular lymphomas at early stage are misdiagnosed as uveitis and proper treatment is often delayed with poor diagnosis due to the lost of best time for treatment. So far, the delay between the diagnosis and the onset of ocular symptoms ranges from 4 to 40 months. Therefore, we should fully understand the early manifestations of intraocular lymphoma and early diagnose and timely treat the disease in order to improve prognosis.
白内障是世界范围内失明的主要原因。正常晶状体是富有弹性的形似双凸透镜的透明体，是机体内蛋白质含量最高的组织，由晶状体囊膜、晶状体上皮细胞、晶状体纤维和悬韧带构成。白内障为晶状体透明度下降，表现为晶状体混浊。近年来随着分子生物学、表观遗传学、免疫学、有机化学等学科快速发展，国内外学者对白内障也进行了大量分子水平的研究，探讨了白内障发生发展相关分子机制，为未来基因治疗和靶向药物等治疗白内障提供了理论基础。对白内障分子病理改变的了解，是白内障精准诊治的基础。
Cataract is the main cause of blindness worldwide. The normal crystalline lens is a transparent biconvex disc,with highest protein content in all human tissues. The lens is composed of capsule, lens epithelial cells, lens fiber and zonular ligment. Cataract is a decrease in the transparency of the lens, which is characterized by opacity. In recent years, with the rapid development of molecular biology, epigenetics, immunology and organic chemistry,researchers have conducted a large number of studies on the molecular basis of genetic or targeted therapy of cataract. It is important to know the molecular pathology of cataract, which is the basis of precise diagnosis and treatment of cataract.
线状皮脂腺痣综合征(linear nevus sebaceous syndrome，LNSS)是一种以皮脂腺痣(nevus sebaceous，NS)为特征性改变，同时合并癫痫、智力迟钝、神经缺陷或骨骼畸形等病变的疾病。本文报道1例经病理组织学检查确诊的LNSS患者，同时伴有双眼脉络膜骨瘤和脑部先天发育异常。由于线状皮脂腺综合征伴双眼多发异常较为少见，本文将总结该例患者的临床和病理表现，旨在为临床诊疗提供一定参考资料。
Linear nevus sebaceous syndrome (LNSS) is a disease characterized by nevus sebaceous (NS) and accompanied by epilepsy, mental retardation, nerve defect or skeletal deformity. We report a case of linear sebaceous nevus syndrome diagnosed by histopathological examination with bilateral choroidal osteoma and congenital developmental abnormalities of the brain. Since linear sebaceous gland syndrome with binocular abnormalities is relatively rare, this paper will summarize the clinical and pathological manifestations of this patient, aiming to provide certain reference for clinical diagnosis and treatment.
眼眶部副神经节瘤极为罕见，多属非功能性肿瘤。本病例为1位中年女性，以右眼眼睑抬举无力为主诉就诊，眼眶计算机断层扫描(computed tomography，CT)和磁共振成像(magnetic resonance imaging，MRI)检查发现右眼眼眶内肿物，手术完整切除，结合HE染色和免疫组织化学检查，病理组织学诊断为眼眶副神经节瘤，随访3年，肿瘤无复发。
Orbital paraganglioma is a rare disease and mostly belongs to non-functional tumors. In this report, we described a middle-aged female admitted to our hospital with the chief complaint of weak lifting of her right eyelid. Orbital computed tomography (CT) and magnetic resonance imaging (MRI) examination detected an intra-orbital mass in the right eye. Complete excision was conducted, and post-operative histopathological and immunohistochemical examination revealed the mass to be orbital paraganglioma. Within the 3-year follow-up,the patient showed no recurrence.
