Anastomosing hemangioma of the renal pelvis: The first case report from Vietnam.

Anastomosing hemangioma is a rare, histopathologically distinct, benign vascular tumor that preferentially involves the genitourinary tract and the paraspinal region. AH can be misdiagnosed as a malignancy such as renal cell carcinoma or angiosarcoma. We present the case of a 71-year-old female patient who was initially diagnosed with cystic renal cell carcinoma based on computed tomography findings. The patient underwent robotic radical nephrectomy, but the pathologic result was AH of the kidney. There was no evidence of recurrence or metastasis 6 months after the surgery.
