Oncocyte
Oncocyte
Oncocyte (pronounced: on-co-site) is a term used in medicine and pathology to describe a large cell with abundant cytoplasm and small, often eccentrically located nucleus. These cells are typically found in certain types of tumors and are characterized by their excessive number of mitochondria. The term "oncocyte" is derived from the Greek words "onkos" meaning mass or bulk, and "kytos" meaning cell.
