The clinico-pathological analysis of choroidal metastatic carcinoma arising from lung carcinoma / 中华眼底病杂志

ABSTRACT

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.
