title: Long-term follow up of renal anastomosing hemangioma mimicking renal angiosarcoma.
abstract: Anastomosing hemangioma of the kidney is a very rare neoplasm, currently 19 cases have been reported in the literature. First described in 2009, histopathologically anastomosing hemangioma is similar to aggressive angiosarcoma. No long-term follow-up data of anastomosing hemangioma have been described yet. Here, we present the case of a healthy 56-year-old man diagnosed in 2002 with a 7 × 5-cm anastomosing hemangioma mimicking an aggressive renal angiosarcoma. The patient underwent nephrectomy and has been followed up disease free for 13 years.
