Anastomosing hemangioma of the kidney: a case report

1

Anastomosing hemangioma (AH) is a rare benign vascular neoplasm primarily found in the testes and genitourinary system.
2

AH is challenging to diagnose preoperatively due to a lack of specific imaging features, often leading to misdiagnosis.
3

A 77-year-old woman was diagnosed with AH after undergoing laparoscopic radical nephrectomy for a suspected cystic renal carcinoma.
4

Postoperative pathology confirmed AH, characterized by proliferating small blood vessels with a reticular anastomosing pattern.
5

AH is recognized as a distinct benign vascular tumor in the 2020 WHO Classification of Soft Tissue Tumours.
