Bilateral choroidal metastases of kidney carcinoma

Metastatic tumors are among the most common intraocular malignancies, and are exclusively localized in the uvea, 88% in the choroids. A 54-year-old male patient was admitted to Urology Department for macrohematuria. A tumor of the left kidney was found. Upon nephrectomy, histopathology indicated papillary carcinoma of the kidney with some focal sarcomatous differentiation. The left suprarenal gland was normal, but one of the regional lymph nodes was invaded. Three years later, the patient was hospitalized again for tumor of the right suprarenal gland and para-aortic tumor. At the same time, the patient complained of visual acuity worsening on the left eye. Fundus examination and fundus photography revealed yellowish subretinal lesions with serous retinal detachment. Metastatic eye lesions may anticipate or follow the diagnosis of kidney carcinoma. All tumors with a tendency of hematogenous metastasizing have a high affinity of metastasizing into the uvea because of its abundant blood flow. Posterior pole is the most common localization ; over 40% of lesions are found in macular region, which is attributed to the higher posterior choroidal blood flow and easy macular symptom detection. That is why kidney carcinoma has to be ruled out in all patients with such yellowish subretinal lesions.
