Abstract
Concomitant occurrence of two different carcinomas in the same organ is rare. Also, it is quite uncommon in thyroid. In this case, three histological types were diagnosed in the same specimen. A 57-year-old patient with a thyroid nodule history, diagnosed 2 years ago. After a suspicious fine needle aspiration cytological result, total thyroidectomy was performed and the histopathological analysis presented three divergent thyroid tumors. There are few thyroid collision tumors cases described, no one with three different histologic types. The lack of clinical information about it, compelled a judicious management, that guided to a satisfatory outcome.
