Anastomosing Haemangioma of the Kidney Involving a Segmental Branch of the Renal Vein

Abstract: Anastomosing variant of capillary haemangioma is a rare and recently described vascular tumour with a proclivity for the genitourinary tract. Here we present the case of a 64-year-old man with incidental finding of 3.4 cm renal mass on CT who had laparoscopic nephrectomy with a good postoperative recovery. Histopathological diagnosis of anastomosing haemangioma of the kidney was made and the patient was followed up for 10 months without evidence of tumour recurrence.

“…7,16,21 In the kidney, it usually involves the renal parenchyma, most frequently the medulla, but the cortex, the renal sinus, the perirenal fat tissue, and the renal vein and its branches may all be involved. 19,21 In the liver, any lobe may be involved, usually in a non-subcapsular location. 11,24 In the bowel, it may have polypoid appearance or involve the muscularis propria, mimicking a gastrointestinal stromal tumor.…”

“…Intravascular extension of the lesion is not rare. 19,21 In cases where AH is identified after investigating another benign or malignant tumor, there is usually no physical association between the 2 lesions. However, a case of collision tumor between an AH and a metastatic clear cell renal carcinoma in the liver has been reported.…”

“…Anastomosing renal haemangioma shows considerable clinical and morphologic overlap with renal angiosarcomas. They share similar clinical features including flank pain, hematuria and abdominal mass; exhibit similar anastomosing pattern on morphology; and are positive for markers of endothelial differentiation on immunohistochemistry [4,34,35]. It is however important to distinguish between both tumours because of the implications on management and prognosis.…”

“…They lack atypical features such as hyperchromatic nuclei, irregular nuclear outline, multilayering, atypical mitotic figures and necrosis. Although cases with tumour infiltration of segmental branches of the renal vein and perinephric fat have been reported, renal haemangiomas are considered benign [34,35]. In contrast to renal angiosarcoma, anastomosing renal haemangioma runs a benign course without evidence of disease recurrence during follow up [34,35].…”

“…Vascular tumors of the kidney are rarely diagnosed entities, despite the fact that the kidney is a highly vascular organ that receives 25% of the cardiac output [ 1 , 2 ]. In the early literature, Virchow was the first to describe benign hemangioma in 1867 [ 3 ].…”
