Thyroid Hyalinizing Trabecular Tumor: A Case Series

Aim: Hyalinizing Trabecular Tumor (HTT) of the thyroid gland is an unusual and rare follicular derived neoplasm, which was first described from Carney and colleagues in 1987. We aim to present two cases of HTT diagnosed as papillary thyroid carcinomas in preoperative FNA cytological findings, although the postoperative histological examinations revealed the presence of Hyalinizing Trabecular tumors. Moreover, a short review regarding the diagnostic and clinical aspects of this rare thyroid tumor is also presented.
