Mucoepidermoid carcinoma, one type of malignant tumor of the salivary glands, is composed ofmucous, squamous and intermediate cells, and mainly occurs as a submucosal lesion in the major salivaryglands, especially the parotid gland. We report a rare tumor arising in the parotid papillary region of aneldery person that was associated with exophytic proliferation. Tumor malignancy is histologically evaluatedon the basis of the relative proportions of mucous cells and squamous cells. Our case had a high proportionof mucous cells, indicating low malignancy and mature type. The tumor apparently arose in the excretingducts of the parotid gland or buccal gland near the parotid papilla and showed polypoid growth tothe oral cavity through the parotid duct.
