Hyalinizing trabecular tumor (HTT) is a rare thyroid tumor of follicular cell origin with a trabecular pattern of growth and marked intertrabecular hyalinization. We herein report a case of HTT in a 26-year-old man with a thyroid goiter. Since the clinical and ultrasonographic features were nonspecific, fine-needle aspiration was performed, which resulted in an indeterminate cytologic diagnosis (category 3). After partial thyroidectomy was performed, an operative rapid pathologic diagnosis revealed that the goiter was a hyalinizing trabecular tumor. The patient therefore did not undergo paratracheal lymph node dissection. There is no unified treatment policy for HTT. If we treat cases of HTT using the protocol for a benign tumor, an operative rapid pathologic diagnosis can provide effective information on whether or not to perform paratracheal lymph node dissection. If we cannot determine the malignancy before the operation, we may still be able to prevent unnecessary paratracheal lymph node dissection by an operative rapid pathologic diagnosis.
