Carcinoid tumors arising in the thymus are rare. Since Rosai and Higa in 1972 distinguished these neoplasms from thymomas, fewer than 100 cases have been reported in the world literature. The pathologic diagnosis of thymic carcinoids is been on findings from light microscopy, histochemical studies, and electron microscopy. About 50% of thymic carcinoids are seen with endocrinopathies. Recurrence and extrathoracic metastasis are characteristic of thymic carcinoids. Surgical extirpation of the tumor initially and of the subseguent recurrences in the most effective treatment today The role of adjuvant radiotherapy and chemotherapy is still uncertain. Herein we report a case of thymic carcinoid tumor in a 36-year old male with brief review of literatures.
