In this issue 1-5 Bronchial carcinoid Tumors: diagnosis and managemenT 5 conTinuing medical educaTion evenTs 6-8 selecTions from The Peer-reviewed liTeraTure 9 lung cancer meeTings and symPosia Carcinoid tumors are rare neuroendocrine tumors that arise from enterochromaffin cells found throughout the gastrointestinal and bronchopulmonary systems. Carcinoids are predominantly found in the gastrointestinal tract, most commonly in the small intestine, but the lung is the second most common site of disease. Bronchopulmonary carcinoid tumors comprise 0.5 to 2% of all lung cancers. The diagnosis is made histologically, based on positive immunohistochemical staining with neuroendocrine markers, such as chromogranin A or CD56 (neural cell adhesion molecule).
