Introduction: Carcinoid tumors are malignant neoplasms of low-malignant neuroendocrine cells. This study tended to evaluate the demographic and rare clinical characteristics of patients with thoracic carcinoid tumor during 2006-2016 at Razi and Aria Hospitals in Rasht. Materials and Methods: The present study was performed on records of 43 patients with lung carcinoid tumors referred to Razi and Aria Hospitals of Rasht during 2006-2019.

Right lower lobe was the most common site of tumor involvement and lobectomy was the most frequent surgical procedure performed. Conclusion: based upon our study the most common clinical sign of thoracic carcinoid was cough and the tumor was pulmonary in 95.3% of cases. Right lower lobe was the most common site of involvement and the most frequent surgical procedure performed was lobectomy. The outcome was good.
