title: Leiomyoma of the thyroid gland with psammoma bodies.
abstract: We report a rare case of leiomyoma of the thyroid gland associated with psammoma bodies. The patient was a 9-year-old black African boy. Prior to this, only five cases of primary thyroid leiomyoma have been reported. Histologically, thyroid leiomyoma was characterised by bundles of spindle smooth muscle cells with blunt-ended nuclei. Psammoma bodies were widely distributed within the tumour. Immunohistochemistry showed positive immunoreactivity for smooth muscle actin, vimentin and desmin, but was negative for a cytokeratin cocktail. Further reports of similar cases is required to ascertain the clinical significance of this lesion.
