Renal cell carcinoma presenting with gross hematuria from a solitary bladder metastasis.

Renal cell carcinoma commonly presents with gross hematuria. We report the first case in which the diagnosis of renal cell carcinoma was made following biopsy of an actively bleeding solitary bladder metastasis of a clear cell carcinoma of the kidney. The possible routes of metastasis of this uncommon lesion are discussed and a review of the literature is presented.
