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.
