Differential diagnosis of follicular adenoma (FA) and follicular carcinoma (FC) of the thyroid can be difficult in the routine practice of surgical pathology because the diagnosis of FC is strictly defined and determined by the presence of capsular and/or vascular invasion by the tumor. These features may be equivocal in the histologic sections. On the other hand, telomerase is expressed in many human cancers and is thought to contribute to their immortality. Human telomerase reverse transcriptase (hTERT) is the major determinant of human telomerase activity, and its expression is suggestive of capacity for unlimited replication. This case-control study examined the expression of hTERT using immunohistochemistry in 36 thyroid FC and 36 FA from patients who were matched by age and sex. The aim was to investigate the value of immunohistochemical staining for hTERT in the differential diagnosis of follicular neoplasms. The results revealed 23 cases of FC and 14 cases of FA that showed high expression of hTERT, with moderate to strong immunoreactivity. The remaining cases showed weak or negative staining. The difference between FA and FC was statistically significant (p < 0.05). In conclusion, immunohistochemical staining for hTERT can be considered an ancillary marker for differential diagnosis of FA and FC.
