The majority of neuroendocrine tumeurs in the gastrointestinal tractor and bronchopulmonary system may mature in the human body. The tumours of neuroendocrine are categorised according to the degree of biological aggression (G1–G3) and the degree of differentiation. Typical (G1) and atypical (G2) carcinoids are the well differentiated neoplasms. Largely distinguished neuroendocrine carcinomas in large cells and small cell carcinomas (G3). Identification and distinction of atypical carcinoids or large-cell neuroendocrine carcinomas and small-cell carcinomas in care choices and pronostics is important. The neuroendocrinal pulmonary tumours are distinguished by proportion of necrosis and mitotic activity, palisading, rosetary, trabecular pattern and organic nesting. The information provided on the histopathological evaluation, characterization, prognoses, genetic aberration and treatment options of neuroendocrine pulmonary tumours is based on their own experiences and on an examination of the present literature. In the identity of typical versus atypical carcinoids atypical versus regular, cell neuropheneous, and big neuroendocrine, large cell carcinomas versus small cell carcinomas, there is a majority of differences between classification of neuroendenocrine tumour entities. Of addition, the classification in small biopsies that can be packed into cytological specimens is constrained by the specimen specificity of the immunohistochemical markers and potential objects. To this day, the prevalence of neuroendocrine pulmonary tumours has increased. As compared to NSCLCs, only little research has been done with respect to new molecular targets as well as improving the classification and differential diagnosis of neuroendocrine tumors of the lung.
