Abstract

Oncocytoma or oncocytic change in salivary glands normally occurs in old patients and mostly in the parotid gland, but those arising from the grossopalatine gland in young patients are extremely rare. The present case shows that oncocytic ductal structures were observed in myoepithelioma, consisting of spindle, plasmacytoid or epithelioid cells. The oncocytic tumor contained large amounts of eosinophilic granular cytoplasm and small nuclei.
