Introduction:
Lobular capillary hemangioma is a benign tumor that commonly occurs in the skin and mucous membranes. A lobular capillary hemangioma that occurs within blood vessels is called intravenous lobular capillary hemangioma. In this report, we report the fifth case of intravenous lobular capillary hemangioma originating from a renal vessel.
Case Presentation:
A 68-year-old man was diagnosed with right renal cell carcinoma with right renal vein tumor thrombus on computed tomography examination for asymptomatic aortic valve stenosis. The patient underwent a robot-assisted laparoscopic radical right nephrectomy and was diagnosed with intravenous lobular capillary hemangioma.
Conclusion:
It is thought that surgical treatment is necessary to differentiate intravenous lobular capillary hemangioma from renal cell carcinoma in preoperative examinations.
