Oncocytoma

Oncocytoma is a type of tumor that is typically benign and occurs in the kidney, salivary glands, and other organs. It is characterized by the presence of large cells, known as oncocytic cells, which have an abundance of mitochondria.

Overview

Oncocytomas are rare and account for approximately 5% of all benign renal tumors. They are usually discovered incidentally during imaging studies for unrelated conditions. Oncocytomas are typically asymptomatic, but they can sometimes cause symptoms such as hematuria (blood in the urine), abdominal pain, and a palpable mass.

Diagnosis

The diagnosis of oncocytoma is usually made based on the results of imaging studies, such as ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI). However, the definitive diagnosis can only be made by examining the tumor under a microscope after it has been removed during surgery.

Treatment

The treatment for oncocytoma depends on the size and location of the tumor, as well as the patient's overall health. In many cases, the tumor can be removed surgically. If the tumor is small and not causing any symptoms, it may be monitored with regular imaging studies to ensure that it is not growing or causing problems.

Prognosis

The prognosis for patients with oncocytoma is generally good, as these tumors are usually benign and do not spread to other parts of the body. However, in rare cases, oncocytomas can become malignant and spread to other organs.
