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.
