Purpose: Neoplasms of the thyroid gland are classified according to the cells they originate from and commonly develop from cells of follicular origin. The most common differentiated thyroid cancers (DTC) are papillary and follicular carcinomas. Coexistence of two different histological types of primary follicular thyroid neoplasm is a rare condition. There are previous reports of concomitant medullary and papillary thyroid cancers. However, there is scarce data about the simultaneous occurrence of the two different histological types of primary follicular thyroid tumors and this is the first study on that subject.
