Case Report

Multiple Renal Capillary Hemangiomas in a Patient with End-Stage Renal Disease

Roozbeh Houshyar

Renal capillary hemangiomas are rare, often underrecognized, benign vascular tumors [1]. In small case series, these lesions have been associated with other diseases including end-stage renal disease, acquired cystic kidney disease, polycythemia, and Renal Cell Carcinoma (RCC) [2-6]. Patients may present with abdominal pain and hematuria, but are more commonly asymptomatic. Therefore, these tumors are often initially discovered incidentally on imaging. Renal hemangiomas pose diagnostic and clinical dilemmas because of similar radiologic characteristics to other lesions including RCC and angiosarcoma. Surgical excision is often indicated due to the similar appearance to malignant lesions or in cases of significant symptoms such as hemorrhage [7-9]. Definitive diagnosis is based on pathology demonstrating aggregates of capillary-sized vascular channels with CD31+ endothelial cells [1,6]. We present a rare case of multiple renal capillary hemangiomas in a patient with end-stage renal disease
