Abstract
Pulmonary carcinoid tumors are uncommon neuroendocrine tumors of the lung that lack invasive characteristics. They are histologically characterized as typical (low grade) or atypical (high grade) carcinoids based on mitotic activity and presence of necrosis. Pulmonary carcinoid tumors most commonly present as asymptomatic, incidental findings on chest radiographs. Diagnosis is confirmed via tissue sampling, although advanced imaging modalities such as somatostatin-based imaging may prove useful. Surgical resection is the primary treatment for these tumors; however, systemic therapies or radiation treatments may be considered in more advanced or medically inoperable setting. Medical therapies may be appropriate for patients with paraneoplastic syndromes, including carcinoid syndrome. Prognosis for patients with typical carcinoids is relatively favorable, although worse in patients with atypical carcinoids.
