title: [Thoracic neuroendocrine tumors].
abstract: Neuroendocrine pulmonary and thymic tumors constitute a distinct category of tumors collectively disclosing morphologic and biologic neuroendocrine features. They are classified in 4 histopathological types and 3 malignancy grades. The typical carcinoids are of low grade, the atypical carcinoids of intermediate grade and the large cell neuroendocrine carcinoma with the small cell carcinoma are high grade neuroendocrine tumors. Their distinction relies on objective morphologic and phenotypic criteria of strong clinical significance and predictive prognostic value.
