Abstract
Until 1972, many carcinoid tumors of the thymus were not recognized as distinct lesions and were mistakenly labeled as variants of thymomas. Thymic carcinoid tumors are unusual neoplasms that show different morphological, functional, and behavioral characteristics than those of thymomas. We report a case of a 65-year-old woman with thymic carcinoid tumor. The cinicopathological findings are discussed with a review of the literature.
