Choroidal Metastasis as an Unusual Initial Presentation of Transitional Cell Carcinoma of the Kidney.

Metastases of transitional cell carcinoma (TCC) of the renal pelvis to the eye is a very rare event, as only one previous case has been described in the literature. We present a patient with choroidal metastasis secondary to TCC of the renal pelvis, with a review of the relevant literature. A 61-year-old male presented with sudden-onset loss of vision of the left eye. Upon evaluation and assessment, the patient was found to have unilateral choroidal metastasis secondary to TCC of the renal pelvis. He is currently on palliative chemotherapy with carboplatin and gemcitabine. External beam radiation therapy is a common mode of treatment and will be considered accordingly.
