  • We report an unusual case of esophageal metastasis protruding through the submucosa from a poorly differentiated thyroid carcinoma (PDTC). (koreamed.org)
  • The term fibroma is inappropriate because the neoplasm exhibits defined histologic features that differ from those of fibromas and may express malignant behavior. (medscape.com)
  • Prior literature reports that this neoplasm takes on an aggressive course and has a strong tendency to recur locally and to metastasize. (bvsalud.org)
  • BACKGROUND: Postoperative routine radioiodine (RAI) treatment is currently debated for patients with low-risk differentiated thyroid carcinoma (DTC) patients. (koreamed.org)
  • PURPOSE: We aimed to develop and validate a simplified, novel quantification method for radioiodine whole-body scans (WBSs) as a predictor for the treatment response in differentiated thyroid carcinoma (DTC) patients. (koreamed.org)
  • Radioiodine activity required for remnant thyroid ablation is of great concern, to avoid unnecessary exposure to radiation and minimize adverse effects. (koreamed.org)
  • Human Thyroid stained with Thyroglobulin Ab (2H11 + 6E1). (novusbio.com)
  • Nearly all thyroid follicular carcinomas stain for thyroglobulin and sometimes produce a focal staining pattern. (genomeme.ca)
  • Conversely, poorly differentiated carcinomas and non-thyroid adenocarcinomas do not stain for thyroglobulin, therefore Anti-Thyroglobulin is a useful diagnostic tool for recognizing papillary and follicular thyroid carcinomas. (genomeme.ca)
  • CREB3L1 knockdown dramatically attenuated invasion of ATC cells, whereas overexpression of CREB3L1 facilitated the invasion of papillary thyroid carcinoma (PTC) cells. (biomedcentral.com)
