Simultaneous choroidal melanoma and renal cell carcinoma in middle-aged patient

BACKGROUND: Although rare, choroid melanoma is the most common intraocular malignancy amongst adults. Similarly, renal cell carcinoma (RCC) is another rare malignancy that counts for 2–3 percent of all adult malignancies. Second primary cancers are not uncommon, even though they occur less frequently than primary cancers. CASE PRESENTATION: We present a rare choroidal melanoma case in a 55-year-old adult who presented with a one -month history of the painless gradual decrease of vision. His investigations revealed a clinical diagnosis of large choroid melanoma, and upon metastatic workup, he was incidentally found to have synchronous RCC. Both malignancies were treated surgically (and the pathology confirmed the clinical diagnosis of choroidal melanoma and RCC). The patient was free of metastatic or recurrent disease at 12 months follow-up.
