Abstract
PDF This study reports a case of anaplastic transformation from a well-differentiated thyroid carcinoma in a young patient. The first recurrent tissue contained poorly differentiated foci that revealed lower thyroglobulin, thyroid transcription factor 1 (TTF-1), and galectin-3 expression than the well-differentiated area. However there was no increased p53 or Ki-67 expression in the poorly differentiated foci, nor in the well-differentiated area. The tissue subsequently relapsed and revealed only anaplastic features, complete loss of thyroglobulin, TTF-1, and galectin-3 expression and revealed an increase in p53 and Ki-67 expression. The
BRAF V600E andBRAF V600V mutation were found in the initially diagnosed papillary thyroid carcinoma and the poorly differentiated foci of the recurring papillary thyroid carcinoma; however, only theBRAF V600V mutation was found in the anaplastic carcinoma. These results suggest that overexpression of p53 and Ki-67 contributed to the anaplastic transformation. We also found that theBRAF type changed during the tumor relapse.-

Abstract
PDF
- BACKGROUND
The macrofollicular variant of papillary thyroid carcinoma (MVPC) is characterized by macrofollicles occupying more than half of the tumor and demonstrating nuclear features of classic papillary carcinoma. It is difficult to recognize on fine needle aspiration (FNA) cytology due to the paucity of aspirated neoplastic cell clusters, especially when the tumor is associated with extensive areas of hemorrhage.
CASE
A 34-year-old female presented with a well-demarcated nodule in the thyroid gland, diagnosed as a benign nodule on ultrasonography and computed tomography. FNA cytology smear revealed a few small aggregates of follicular cells with morphological features suspicious for papillary carcinoma, set in a background of hemorrhage, inflammatory cells, and hemosiderin-laden macrophages. Intraoperative frozen section revealed macrofollicular nests filled with hemorrhage and composed of follicular cells demonstrating nuclear clearing and grooves.
CONCLUSION
MVPC is a rare but distinctive variant of papillary carcinoma, which is easily mistaken for adenomatous goiter or benign macrofollicular neoplasm on radiologic findings. The cytopathologist should alert oneself on encountering benign radiologic findings and any smear composed of scant numbers of follicular cells with nuclear features suspicious for papillary carcinoma despite the bland-looking background of hemorrhage and hemosiderin-laden macrophages, and recommend intraoperative frozen sections for a definite diagnosis.
