Haemangioma of the Urinary Tract: Review of the Literature

Abstract

General features. Haemangiomas are benign vascular tumours. They can regress spontaneously as a result of fibrosclerosis, suggesting a conservative approach wherever possible. Asymptomatic haemangiomas do not require treatment. Renal haemangioma. In all, 198 cases have been reported. The lesion is usually solitary and unilateral and occurs most often in the pyramid, and in the mucosa or subepithelial tissue of the pelvis. In some cases a tentative diagnosis of haemangioma has been made by means of selective renal angiography and pre- or per-operative renoscopy. Partial nephrectomy is recommended in cases of minor haemangioma. Ureteric haemangioma. Six cases have been described. When haemangioma is suspected a conservative operation is recommended. Bladder haemangioma. A total of 106 cases have been reported. Many of the tumours had the characteristics of an iceberg, with considerable extravesical extension making endoscopic management less suitable because of the possibility of massive haemorrhage or recurrence. Consequently, many authors prefer local excision. In the case of endoscopic treatment the patient should be prepared for open surgery. Urethral haemangioma. Twenty cases have been described. The lesions often extend further than is immediately apparent. Endoscopic management is recommended for small lesions and, in the case of more extensive lesions, open exploration is advised followed by appropriate urethral reconstruction.

A case of perirenal hemangioma mimicking renal cell carcinoma

“…They commonly occur in the mucosa or submucosa of the pelvis (48.7%), in the pyramid of the kidney (42.1%) and, occasionally, in the cortex (9.2%). 1 Hemangiomas of the renal capsule or perirenal area are extremely rare. Wang et al described the first case of hemangioma arising from the renal capsule.…”

Misdiagnosis of pathological femoral fracture in a patient with intramuscular hemangioma: A case report

“…Hemangiomas account for 7-10% of all soft-tissue tumors (6,7). IH is the most common type of deep soft-tissue hemangioma, one of the most common types of deep-seated soft tissue tumors, as well as the most common type of benign tumors of muscle (5).…”

Cavernous Hemangioma of the Ureter

“…According to previous reports, renal hemangiomas are the most common and the next frequent urinary hemangioma is hemangioma of the bladder. 1 Hemangiomas of the renal pelvis, adrenal gland, scrotum, penis, prepuce, spermatic cord, kidney, and bladder have been reported in Korea. [4][5][6][7] Ureteral hemangiomas are a very rare benign ureteral tumor, and only 8 cases have been reported in the world; the ureteral hemangioma reported here is the first case reported in Korea.…”

“…[4][5][6][7] Ureteral hemangiomas are a very rare benign ureteral tumor, and only 8 cases have been reported in the world; the ureteral hemangioma reported here is the first case reported in Korea. [1][2][3] Clinically, patients usually presented with hematuria due to thrombus, infarction, and angiogenesis by erosion of the urothelium. Flank pain due to ureteral obstruction was reported, although some patients may be asymptomatic.…”

“…[1][2][3] Most ureteral hemangiomas are diagnosed by pathologic examination after surgery. Here we describe a case of a ureteral hemangioma diagnosed by pathologic examination after endoscopic removal.…”
