A 50-year-old male patient was referred for an assessment of a choroidal lesion in the right eye. He also noticed a rapidly growing caruncle lesion about 2 weeks prior to his visit. His medical history was remarkable for metastatic diseases from clear cell renal carcinoma 1 year before.
On ophthalmic evaluation, his visual acuity was 20/20 in both eyes. Anterior segment examination of the right eye showed a red protruding mass at the caruncle [Figure 1]. Dilated fundus examination demonstrated an amelanotic choroidal lesion at the inferior temporal arcade [Figure 2]. Ultrasound examination identified a dome-shaped choroidal tumor, with medium internal reflectivity [Figure 3]. The left eye examination was normal. The caruncle tumor was excised totally. Histopathological examination revealed nests of clear cells with abundant cytoplasm, which confirmed a metastatic renal cell carcinoma (RCC) [Figure 4]. The right eye was treated with radiotherapy in addition to the second line of systemic targeted therapy. There is no recurrence of conjunctival tumor or choroidal tumors 18 months after treatment [Figure 5].

| Discussion|| |
Choroidal metastasis from RCC accounts for only 3% of all choroidal metastases.,, There were only three cases of conjunctival metastasis from RCC reported in the literature., Two cases presented with a unilateral conjunctival mass as the first presentation of RCC. The third case presented with bilateral choroidal metastases from RCC and developed bilateral conjunctival metastases 6 months later.
This is a patient who has an advanced stage of RCC, which is refractory to first-line targeted therapy and immunotherapy. The biopsy of the tumor at caruncle confirmed the nature of the intraocular tumor. To the best of our knowledge, this is the first case to describe concurrent conjunctival and choroidal metastases from RCC, which may represent a more aggressive phenotype of RCC, and requires close monitoring of advanced disease.
