Spontaneous rupture of the kidney in the patients with synchronous renal hemangioma and nephrogenic hypertension

Abstract

Most renal neoplasms in adults are epithelial in origin and mesenchymal tumors are rarely encountered. Vascular tumors and tumor-like lesions account for a very small subset. Hemangioma of the kidney is a rarely seen benign vascular neoplasm that probably arises from angioblastic cells. Its general sign is macroscopic hematuria with or without pain. Preoperative diagnosis is difficult or impossible. Previously, spontaneous rupture of the kidney caused by renal hemangioma was not reported in the English literature. In this study, two cases with a history of nephrogenic hypertension who presented with spontaneous renal rupture are presented. There wasn't any trauma history in the background of our patients. A long-standing nephrogenic hypertension was present in both patients. Patients underwent radical nephrectomy due to rupture of the renal tumor. In histopathological examination, capillary hemangioma was detected in the renal medulla in both cases. Patients didn't need antihypertensive therapy during the postoperative period.

Case report: Capillary hemangioma in the renal hilum mimicking paraganglioma

“…Most of these tumors occur in the skin, subcutaneous tissue, and oral mucosa, such as the tongue, lips, bottom of the mouth and other tissues. They may also occur in internal viscera, such as the liver, spleen, gastrointestinal tract ( 10 ), omentum ( 11 ), and kidney ( 4 ).…”

“…It is a congenital tumor or vascular malformation commonly found in the skin and soft tissues and is caused by the proliferation of vasculogenic cells during the embryonic period ( 1 , 2 ). Its presence in the kidney is rare, and there have been only case reports in the English literature ( 3 , 4 ). Renal hemangiomas are usually solitary and unilateral.…”

Spontaneous Kidney Rupture: Two Case Reports With Unusual Presentations

“…In addition, he had untreated hypertension. We have encountered the only case reports in the literature regarding the development of SKR in patients with nephrogenic hypertension [ 10 ]. In this report, it is seen that SKR is caused by renal hemangiomas accompanied by hypertension.…”

Renal Capillary Hemangioma Mimicking Urothelial Carcinoma, A Case Report and Review of the Literature

“…There are very rare case reports of renal capillary hemangioma (5). To the best of our knowledge, there have been less than 30 cases of renal capillary hemangioma reported in the English literature since 2000 (6-14).…”
