[Thyroid paraganglioma: report of a case].

A case of thyroid gland paraganglioma is reported in a 48-year-old woman with cold thyroid nodule. Review of the literature reveals only 4 cases of intrathyroidal paraganglioma but none of them have complete immunohistochemical study. The main differential diagnosis in this localization, namely medullary carcinoma and trabecular hyalinizing adenoma, are discussed.
