Renal oncocytoma
Renal Oncocytoma
Renal Oncocytoma (pronounced: ree-nal on-ko-sigh-toe-ma) is a benign tumor that occurs in the kidney. It is often discovered incidentally during imaging studies for other conditions.
Etymology
The term "Renal Oncocytoma" is derived from the Greek words "onkos" meaning mass, and "cytoma" meaning cell. The prefix "Renal" refers to the kidney, the organ in which this tumor is found.
Definition
Renal Oncocytoma is a type of benign neoplasm that originates from the intercalated cells of the collecting ducts in the kidney. Despite its benign nature, it can sometimes be difficult to distinguish from malignant renal cell carcinoma, particularly on imaging studies.
Symptoms
Most Renal Oncocytomas are asymptomatic and are discovered incidentally. However, if symptoms do occur, they may include hematuria (blood in the urine), flank pain, or a palpable mass in the abdomen.
Diagnosis
Diagnosis of Renal Oncocytoma is typically made through imaging studies such as ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI). However, definitive diagnosis often requires a biopsy of the tumor.
Treatment
Treatment for Renal Oncocytoma typically involves surgical removal of the tumor. This can often be accomplished through minimally invasive techniques such as laparoscopic surgery or robotic surgery. In some cases, active surveillance may be an option if the tumor is small and not causing symptoms.
Prognosis
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 is necessary to monitor for potential recurrence.
