Oncocyte

Oncocytes are tumor cells that are characterized by morphological and functional features that distinguish them from normal cells. The cells are distinguished by their large size, primitive structure and high proliferative activity. This term was first proposed by the German histologist Rudolf Kafka in 1968.

***Tumor cells*** are cellular formations that are in biological equilibrium with the body due to the production of an unlimited amount of abnormal waste products, growth and decay. This biochemical activity leads to a restructuring of the body due to disorders of tissue nutrition and connections between tissues. As a result, tissue potential changes and morphological atypia occurs. Conventionally, tumor elements are divided into three groups: ***normal oncocytes, benign and malignant***. *A tumor cell is a special participant in the complex process of metamorphosis of a normal cell.* Various features of a tumor cell determine its behavior and overall effect on the body. Understanding the morphology and biology of tumor cells is a key component in developing strategies to combat cancer. That is why oncocytological analysis plays an important role in clinical oncology. This method allows
