To examine the immunohistochemical alterations associated with the histological dedifferentiation of thyroid carcinomas, we performed staining for HBME-1, high molecular excess weight cytokeratin (HCK), CK 19, thyroid transcription element-1 (TTF-1) and E-cadherin (E-CD) about 125 various types of thyroid carcinomas. These results suggest that HBME-1 may be a marker for well-differentiated carcinomas while CK19 and… Continue reading To examine the immunohistochemical alterations associated with the histological dedifferentiation of
