follicular adenocarcinoma /fōlik′yələr/ , a neoplasm characterized by a follicular arrangement of cells often seen in the thyroid gland, occurring most often in older individuals. The follicular thyroid carcinoma has a tendency to metastasize distantly to the lungs and bones. Surgery is the preferred treatment. If complete excision of the primary tumor is not feasible, radioiodine therapy is indicated. See also medullary carcinoma, papillary adenocarcinoma.
