[Tyrosine-rich crystalloids in a myoepithelioma of the minor salivary glands in the smooth palate].
Tyrosine-rich crystalloids in tumors of the salivary glands are rare and have been reported mainly in specimens from Black African patients. The pathogenesis of these structures is still unclear, but pathological secretion by neoplastic myoepithelial cells is supposed. Millon's staining and ultrastructural examinations are used for confirming the diagnosis. We present the case report of a 59-year-old woman with a myoepithelioma of the minor salivary glands in the smooth palate containing tyrosine-rich crystalloids as an example of this rare phenomenon.
