چکیده
Hyalinizing trabecular adenoma (HTA) is a follicle-derived tumor of the thyroid gland that has been described recently. The differential diagnosis includes medullar carcinoma, papillary carcinoma, and paraganglioma of the thyroid. We report a case of thyroid HTA in a 25-year-old woman. The tumor appeared as a <> of the left thyroid in radionuclide scans. Histologically, the tumor showed tumor cells arranged in trabeculae and a prominent hyaline stroma. The neoplastic cells were focally immunoreactive for thyroglobulin and negative for calcitonin, chromogranin, and S-100 protein. Three years after hemithyroidectomy, the patient is alive and free of disease.

Subsequent reports concerning hyalinizing trabecular carcinoma further complicated its c...
