肺癌脉络膜转移的临床病理分析

目的 观察肺癌脉络膜转移的临床及病理组织学特征。 方法 回顾性分析6例经病理组织学检查确诊为源自肺癌脉络膜转移患者的临床特征、影像学表现、病理组织学改变、分型。 结果 6例患者均表现为严重视力障碍，3例患者有剧烈眼痛。6例患者可见后极部扁平实质性占位病灶,5例患者伴视网膜脱离；1例患者行荧光素眼底血管造影（fundus flourescein angiography，FFA）检查，发现有遮蔽荧光和透见荧光相间的病灶，其边缘有针尖大小的荧光渗漏环；3例患者行眼部CT扫描检查，均表现为扁平状均质中高密度肿块影；1例行MRI扫描检查， T1W呈高于玻璃体的高信号, T2W瘤体呈低信号；5例患者肺部原发病变病理组织学检查诊断为肺腺癌，1例诊断为小细胞肺癌。脉络膜转移癌5例病理诊断为肺腺癌脉络膜转移 ，1例为小细胞癌肺癌脉络膜转移。 结论 源自肺癌的脉络膜转移癌以视力骤降、眼痛、眼底扁平实质性占位病灶及继发视网膜脱离为主要的临床表现。转移癌的病理组织学表现多与原发病灶相似，组织学分型以腺癌常见。 （中华眼底病杂志，2003，19：333-404）

The clinico-pathological analysis of choroidal metastatic carcinoma arising from lung carcinoma

Objective To observe the clinical and pathological characteristics of choroidal metastatic carcinoma from lung carcinoma. Methods The clinical and pathological data of 6 patients with choroidal metastatic carcinoma from lung carcinima were analysed retrospectively. Results All the 6 patients had severe visual impairment, including 3 with severe ophthalmalgia. Flat neoplasm were seen in the posterior pole of the eyes in all the 6 patients and retinal detachment were found in 5 patients. Fundus fluorescein angiography (FFA) examination had been performed on 1 patient and blocked fluorescence and hyperfluorescence were seen in the lesion with pinpoint fluorescein leakage loop around it. CT examination had been performed on 3 patients and the shadow of flat homogenous tumor was seen. MRI examination had been performed on 1 patient and high signal intensities on T1W and low signal intensities on T2W were found. In all the 6 patients with primary lung carcinoma, 5 were diagnosed with adenocarcinoma and 1 with cellule carcinoma through pathological examination, and 5 patients were diagnosed with choroidal metastatic carcinoma from adenocarcinoma and 1 with choroidal metastatic carcinoma from cellule carcinoma through pathological examination. Conclusion Rapid visual acuity decrease, severe ophthalmalgia, flat neoplasm in ocular fundus and secondary retinal detachment are the main clinical characteristics of the choroidal metastatic carcinoma from lung carcinoma. Most histopathological manifestations of the metastatic carcinoma like that of the primary focus, and adenocarninoma is the most common histoclassification.
