Abstract

The hyalinizing trabecular adenoma (HTA) of the thyroid gland is a rare benign tumor, which is characterized by a trabecular growth pattern with hyaline stroma. This tumor is occasionally misdiagnosed as papillary carcinoma and medullary carcinoma. Distinguishing pathologic findings and immunochemical studies are needed to make a definite diagnosis. Recently, we experienced a case of HTA of the thyroid gland. A 54-year-old woman presented with both thyroid nodules (mainly the left thyroid). Fine needle aspiration cytology showed atypical follicular cells. We performed left hemithyroidectomy and finally diagnosed the specimen as HTA. We present this rare case with a brief review of the disease entity.
