Somika Sethi et al. Urol Ann. 2012 Sep.

Abstract

Hemangioma of kidney is a rare benign tumor. Although it may be clinically silent, their main symptom is hematuria, sometimes profuse and relapsing. We report two such cases which presented with episodes of hematuria and were clinically and radiologically diagnosed as transitional cell carcinoma. Nephrectomy was performed in both cases and the histopathological appearance were those of a cavernous hemangioma. A literature review of renal hemangioma is also presented.

Keywords: Hematuria; hemangioma; kidney.
