Renal oncocytoma is a type of tumor that originates in the kidney. It is a benign neoplasm, meaning it does not spread to other parts of the body. Renal oncocytomas are often discovered incidentally during imaging tests for other conditions.
Symptoms[edit]
Renal oncocytomas are usually asymptomatic, meaning they do not cause any symptoms. However, in some cases, they may cause hematuria (blood in the urine), abdominal pain, or a palpable abdominal mass.
Diagnosis[edit]
The diagnosis of renal oncocytoma is often challenging because it can look similar to other types of kidney tumors on imaging tests. The definitive diagnosis is usually made after a biopsy or surgical removal of the tumor, when a pathologist can examine the cells under a microscope.
Treatment[edit]
The treatment for renal oncocytoma is usually surgical removal of the tumor. This can often be done with a nephron-sparing surgery, which preserves as much of the healthy kidney tissue as possible. In some cases, the entire kidney may need to be removed (nephrectomy).
Prognosis[edit]
The prognosis for renal oncocytoma is generally excellent, as these tumors are benign and do not spread to other parts of the body. However, regular follow-up with imaging tests is often recommended to monitor for any changes in the tumor.
