     The mean age at diagnosis was 38 years, ranged from 5-64 years. According to the histopathological examination, melanoma was the most common tumor in the iris and ciliary body (15 cases, 40.5%),followed by metastatic tumors (8 cases, 21.6%),teratoid medulloepitheliomas (3 cases, 8.1%) and iris nevus (2 cases, 5.4%).

Objective To investigate the character of anterior segment tumor by ultrasound biomicroscopy(UBM).Methods UBM was used to diagnose 55 patients of anterior segment tumors,such as iris cyst,iris nevi and ciliary body tumors.Results UBM showed iris cyst was circular or ellipse with smooth surface and thin wall,but no reflectivify.iris nevus was of anteriorly convex shape in fusifarm or semicircles,its superficial layer can reflects as same as iris.Ciliary body tumors was of anteriorly convex shape...

目的 了解眼前节常见肿瘤的超声生物显微镜表现特点。方法 应用超声生物显微镜对55例常见眼前节肿瘤~虹膜囊肿、虹膜色素痣、睫状体肿瘤进行观察。结果 超声生物显微镜表现:虹膜囊肿为边界清晰的圆形或椭圆形囊样病变,内部为无回声区;虹膜色素痣为边界清晰的局限隆起,可为梭形、半球形等,内部回声均匀且与虹膜组织基本相同;睫状体肿瘤表现为睫状体局限隆起,可为半球形或蘑菇形,内部回声不均匀,前界回声强,后界回声弱,可伴有虹膜囊肿,继发脉络膜上腔渗漏。结论 超声生物显微镜对虹膜肿瘤可明确鉴别实性或囊性,睫状体肿瘤的基底部亦可详尽观察,超声生物显微镜是一种新的无创评估眼前节肿瘤的诊断方法。

ObjectiveTo evaluate the clinical features, different diagnosis, pathological features, management, and prognosis of tumors of the iris and ciliary body. MethodsMedical records, photographs, pathological findings and the results of follow-up of 37 cases with tumors of the iris and ciliary body were reviewed as a retrospective study. ResultsOf the 37 cases with tumors of the iris and ciliary body, 26 were male and 11 were female. The mean age at diagnosis was 38 years, ranged from 5-64 years. According to the histopathological examination, melanoma was the most common tumor in the iris and ciliary body (15 cases, 40.5%),followed by metastatic tumors (8 cases, 21.6%),teratoid medulloepitheliomas (3 cases, 8.1%) and iris nevus (2 cases, 5.4%). Management: The tumors were excised in 14 cases. Enucleation was performed in 21 cases. Two cases were observed without any surgical treatment. Thirty-four cases were followed-up for 2 months to 15 years, averaged 31 months. Most melanomas of the iris and ciliary body are round or semi-spherical dark brown vascularized mass, with engorged episcleral sentinel vessels in some cases. The tumor showed a shadow during transillumination. Ultrasound biomicroscopy revealed a low to medium echoic solid lesion,with echoic changes in adjacent infiltrated tissues. Melanoma showed positive immunoreactivity for melanoma-specific antigen, and had a good prognosis. Metastatic tumors of the iris and ciliary body were flat or near round, dirty, single or multiple neoplasms, growth rapidly, with abundant neovascularization, and had a poor prognosis. Primary carcinomas could be found in other parts of the body. ConclusionsMelanoma of the iris and ciliary body has typical features that may help to distinguish them from other tumors. Metastatic tumor has characteristic features, but the diagnosis can be made only with supplementary examination and immunocytochemical studies. Medulloepitheliomas should be differentiated from retinoblastoma.

目的 分析虹膜睫状体肿瘤患者的临床表现、鉴别诊断要点、病理组织学特征、处理及预后。方法 对 196 6年 1月至 2 0 0 0年 12月经病理检查证实的 37例虹膜睫状体肿瘤的临床和病理资料进行回顾性分析。结果 按病理组织学分类 ,第一位为虹膜睫状体黑色素瘤 15例 ( 40 5 % ) ,其他依次为虹膜睫状体转移癌 8例 ( 2 1 6 % )、睫状体髓上皮瘤 3例 ( 8 1% )、虹膜色素痣 2例 ( 5 4% )及其他 9例 ( 2 4 3% )。处理方法 :局部切除 14例 ( 37 8% ) ,眼球摘除 2 1例 ( 5 6 8% ) ,活检后观察 2例( 5 4% )。对其中的 34例随访 2个月至 15年 ,平均 31个月。虹膜睫状体黑色素瘤多呈半球形或球形的棕黑色实性肿物 ,肿瘤内有丰富的新生血管 ,部分睫状体黑色素瘤邻近的表层巩膜有“哨兵”样血管 ,巩膜透照试验瘤体不透光 ;超声生物显微镜检查示低至中等回声图像 ,邻近受累组织回声及形态异常 ,对黑色素瘤特异性抗原呈阳性反应 ,预后较好。虹膜睫状体转移癌可为单发或多发 ,肿瘤扁平隆起或近似球形 ,色泽污秽 ,有丰富的新生血管 ,生...
