Hemangiomas of the kidney are rare benign tumors. The tumors are usually single, seldom multiple or bilateral, and there is no evident predominance according to race, sex, or side of the kidney. Although they can be clinically silent, their main symptom is hematuria, sometimes profuse or relapsing. A case of hemangioma in the middle portion of the right kidney is reported. The 56-years-old male patient was found to have a right renal mass incidentally by abdominal ultrasonography, owing to a gastrointestinal complaint. The roentgenological manifestations closely resembled renal cell carcinoma. Nephrectomy was performed. The histopathological appearance was cavernous hemangioma with numerous small and large vascular channels. A literature review of renal hemangioma is also presented.
