Abstract:
We present a very rare case of simultaneous thymic carcinoids with similar size, one of which showed spontaneous regression. A 68-year-old man was admitted to the hospital because of two similar abnormal masses at his anterior mediastinum on chest computed tomography, one of which had decreased from 25 to 16 mm in diameter. A total thymectomy was performed and the pathologic examinations revealed that both tumors were atypical carcinoids. There have been seldom reports of multiple thymic carcinoids, and this case might suggest that total thymectomy is the best way to treat thymic carcinoid because of the possibility of multicentric origins.
