follicular carcinoma

fol·lic·u·lar car·ci·no·ma

carcinoma of the thyroid composed of well-differentiated or poorly differentiated epithelial follicles without papillary formation, which is difficult to distinguish from adenoma; the criteria include blood vessel invasion and the finding of metastases of follicular thyroid tissue in other structures such as cervical lymph nodes and bone; follicular carcinoma may take up radioactive iodine.
