Background. We report a rare case of typical pulmonary carcinoid with mediastinal lymph node metastasis. Case. A 62-year-old man was admitted to our hospital for further examination of an abnormal shadow on a chest roentgenogram. Chest CT scan showed a 18× 18 mm tumor in the middle lobe. With a diagnosis of primary pulmonary small cell carcinoma, a middle lobectomy with mediastinal lymph node dissection was done. The pathological diagnosis of the resected specimen was typical carcinoid. All areas of the tumor was immunohistochemically positive for chromogranin A, NSE, and N-CAM. Subcarinal lymph nodes were metastatic from the carcinoid tumor. Conclusion. A limited operation is thought to be acceptable only in patients with typical carcinoid in a peripheral lesion without lymph node metastasis. Lobectomy with mediastinal lymph node dissection is necessary for possibly metastatic case.
