Figure 1 Morphologic criteria for distinguishing lung NETs. Tumors with neuroendocrine morphology are divided into the four subtypes primarily according to the number of mitoses and presence or absence of necrosis. NET, neuroendocrine tumor; NE, neuroendocrine. Adapted from Travis8 with permission.

Figure 3 Diagnostic evaluation/work-up recommendations according to the European Neuroendocrine Tumor Society guidelines for typical carcinoids (TCs) and atypical carcinoids (ACs). aAccurate echocardiographic evaluation should always be carried out before surgical procedures and at both diagnosis and follow-up to evaluate the presence and evolution of carcinoid heart disease. NET, neuroendocrine tumor; MEN-1, multiple endocrine neoplasia type 1; PTH, parathyroid hormone; CT, computed tomography; 5-HIAA, 5-hydroxyindoleacetic acid; ACTH, adrenocorticotropic hormone; GHRH, growth hormone–releasing hormone; IGF-1, insulin growth factor 1; MRI, magnetic resonance imaging; EBUS, endobronchial ultrasonography; PET, positron emission tomography; FDG-PET, fludeoxyglucose F 18 positron emission tomography.
