Anastomosing hemangioma (AH) is a rare subtype of primary vascular tumor that can, clinically and radiologically, mimic malignant renal tumors such as renal cell carcinoma (RCC) and angiosarcoma. It poses a diagnostic dilemma for the clinicians because of its rarity and the overlapping features it shares with other renal vascular tumors. Here we report a case of AH that occurred in a 25 year male patient presented initially as a renal mass that was provisionally diagnosed as RCC based upon imaging . The patient was treated with Laparoscopic Right radical nephrectomy. The histopathology showed tumor tissue composed of tightly packed capillary channels with a focal anastomosing sinusoidal like pattern. As a clinician we should be aware of this rare entity as one of the possible histopathological diagnoses.
