The neuroendocrine system is fascinating. It is an intriguing, complex system. For centuries, it has sustained the interest of scientists, who have provided the community with a wealth of information on neuroendocrine tumors types鈥攈istory, genetics, clinical presentation, surgical pathology, differential diagnoses鈥n everything except cytopathology鈥ntil now. This one-of-a-kind color atlas fills a long-standing void in neuroendocrine resources. This atlas provides clear, descriptive information on the cytopathology of neuroendocrine tumor types and differential diagnoses in one cutting-edge, comprehensive resource. This unique atlas is dedicated exclusively to providing expert, illustrated coverage of the cytopathology of neuroendocrine tumors. Inside, the content addresses the wide distribution of the neuroendocrine cells in the body and the ubiquitous nature of their neoplasms. Readers will also explore detailed descriptions of the morphologic spectrum of the neoplasms (including different terminologies), as well as their immunocytohistochemical properties, associated ultrastructural findings, secretory products, and their association with many hereditary syndrome
