title: Retroperitoneal lobular capillary hemangioma with synchronous ipsilateral renal cell carcinoma.
abstract: Lobular capillary hemangiomas (LCH) are acquired benign vascular tumors of skin and mucosal spaces of head and neck. Very few cases of LCH have been reported in the abdomen, predominantly occurring as mucosal polyps in the bowel. We present CT imaging features of solitary retroperitoneal LCH in a patient with synchronous ipsilateral renal cell carcinoma and review the available literature and imaging features in abdominal and extra-abdominal LCH. To our knowledge, there is no other case of retroperitoneal LCH available in the English literature.
