Background. Thymic carcinoids are rare disease to account for ２-４％ of anterior mediastinal tumors. So, the clinicopathologic characters are not known enough. Case. A ６７ years old man was followed up old myocardial infarction, and he was taken chest CT scan for evaluate coronary artery. It revealed three anterior mediastinal tumors and we diagnosed thymoma by needle biopsy. We treated by neoadjuvant chemotherapy（CAMP therapy）, but it was ineffective. We performed thoracoscopic thymothymomectomy, and the pathological diagnosis was thymic atypical carcinoid. He is free of clinically event recurrence one year and a half after treatment. Conclusions. When we found an anterior mediastinal tumor, and if the clinical course is usually different, we should consider the possibility of a thymic carcinoid.
