Oncocytoma
Oncocytoma
Oncocytoma (pronounced: on-koh-sigh-toh-muh) is a type of benign tumor that typically arises in the salivary glands, kidneys, or thyroid gland. The term "oncocytoma" is derived from the Greek words "onkos" (mass or bulk) and "cytoma" (tumor), indicating a tumor composed of large, eosinophilic cells, known as oncocytes.
Etymology
The term "oncocytoma" is derived from the Greek words "onkos" meaning mass or bulk, and "cytoma" meaning tumor. The suffix "-oma" is used in medical terminology to denote a benign tumor. The term "oncocyte" refers to the large, eosinophilic cells that make up these tumors, and is derived from the Greek words "onkos" and "kytos" meaning cell.
Description
Oncocytomas are benign tumors that are typically slow-growing and non-invasive. They are composed of oncocytes, which are large, eosinophilic cells with abundant, granular cytoplasm. Oncocytomas can occur in various organs, but are most commonly found in the salivary glands, kidneys, and thyroid gland.
Diagnosis
Diagnosis of oncocytoma typically involves imaging studies such as CT scans or MRI, and may be confirmed with a biopsy. The appearance of the tumor on imaging and its histological features can help distinguish it from other types of tumors.
Treatment
Treatment for oncocytoma depends on the location and size of the tumor. In many cases, surgical removal of the tumor is the preferred treatment. However, in cases where the tumor is small and not causing any symptoms, a watchful waiting approach may be taken.
