Hemangioma is a benign vascular tumor.
Hemangioma of the urogenital tract is rare and reports consist mainly of single cases or small series. However, hemangiomas were detected in 8.8% of kidneys removed for end-stage renal disease.
It occurs at all ages, including infants. The median is in the sixth decade.
Hemangiomas of the kidney and the bladder occur more frequently in males.
Urogenital hemangiomas arise more frequently in the kidney and the bladder.
Surgery is the primary treatment. Embolization of the lesion may be considered to reduce the bleeding.
Hemangioma is a benign tumor that does not recur after complete excision.
Grossly, hemangiomas appear as hemorrhagic lesions ranging in size from 0.5 to 9 cm.
