摘　　要：BACKGROUND Pulmonary carcinoids are rare,low-grade malignant tumors characterized by neuroendocrine differentiation and relatively indolent clinical behavior.Most cases present as a slow-growing polypoidal mass in the major bronchi leading to hemoptysis and pulmonary infection due to blockage of the distal bronchi.Carcinoid syndrome is a paraneoplastic syndrome caused by the systemic release of vasoactive substances that presents in 5%of patients with neuroendocrine tumors.Due to such nonspecific presentation,most patients are misdiagnosed or diagnosed late and may receive several courses of antibiotics to treat recurrent pneumonia before the tumor is diagnosed.CASE SUMMARY We report the case of a 48-year-old male who presented with cough,dyspnea,a history of recurrent pneumonitis,and therapy-refractory ulcerative colitis that completely subsided after the resection of a pulmonary carcinoid.CONCLUSION We report and emphasize pulmonary carcinoid as a differential diagnosis in patients with nonresponding inflammatory bowel diseases and recurrent pneumonia.
