Neuroepithelioma

Neuroepithelioma is a malignant tumor that develops from neuroepithelial cells. These cells form nerve tissue and are found in the brain and spinal cord, as well as in other organs and tissues of the body.

Neuroepitheliomas can occur at any age, but they are most common in people over 50 years of age. They can be either benign or malignant. Benign neuroepitheliomas usually do not cause symptoms, but can grow and press on nearby tissue, causing pain and discomfort. Malignant neuroepitheliomas, in turn, can metastasize to other organs and tissues, which can lead to serious complications and even death.

Treatment of neuroepitheliomas depends on their type and stage of the disease. In some cases, surgical removal of the tumor may be performed, but in other cases, radiation therapy or chemotherapy may be required. The prognosis for neuroepitheliomas can vary, but with early detection and proper treatment, good results can be achieved.

Neuroendocrine tumor in medical practice

In 1923, **Alfred Hoffmann**, a famous German doctor, proposed the name **neuroendocrine tumors**. Alfred acknowledged that these tumors cannot be grouped with the better-known group called _neuroglioma_. They represented a group of benign neoplasms and intermediate tumors that arose from the ranks of neuroblasts. He argued that **they represented a tumor imitating neurohydropus, originating from the neurons of cells**, but not in the same sense as biochemists believed **could be subject to the hormonal processes inherent in neurons**. It was believed that in endocrinological neoplasms there was a disorder that mimicked the hormones produced by the glands **produced by neurons**. Soon, almost all opinions regarding the existence of newly formed neuroendocrinal formations were recognized as erroneous, and the groups identified by Alfred Hoffman - “atrophic” and “extreme”, later renamed neurocarcinomas I and
