Sporadic hemangioblastoma of the kidney; a rare entity and a potential diagnostic challenge

Key Points

This research aims to illustrate the diagnostic challenges of sporadic renal hemangioblastoma, particularly in distinguishing it from similar tumors.
Presented two cases of renal hemangioblastoma misdiagnosed as renal cell carcinoma.
Utilized immunohistochemical studies to confirm the diagnosis.
Both cases showed similarities to renal cell carcinoma, complicating initial diagnoses.
Immunohistochemical confirmation established both tumors as renal hemangioblastoma.

Abstract

Hemangioblastoma is a benign tumor of central nervous system (CNS) which may rarely occur in extraneural tissues. Renal hemangioblastoma (RH) occurs sporadic or in the setting of Von-hipple-lindau syndrome. It is usually misdiagnosed as other renal masses including renal cell carcinoma (RCC) due to their similar clinical and histologic features. In this paper, we present two cases of RH which resembled RCC, however immunohistochemical studies confirmed diagnosis of RH.
