Abstract

Abstract: Mucinous cystadenoma (MCA) usually occurs in the appendix, ovary, kidney, and pancreas. MCA is sometimes considered a borderline tumor. In the oral and maxillofacial region, MCA most commonly occurs in the parotid glands and the minor salivary glands; however, the frequency is low.<BR>We describe a 65-year-old woman who had a slowly enlarging tumor, 10mm in diameter, in the hard palate. Magnetic resonance images of the lesion revealed hyperintensity on both Ti-weighted and T2-weighted images. The tumor was successfully excised.<BR>Histologically, the tumor was surrounded by a fibrous capsule, and cystic spaces werelined by mucus-producing cells or goblet cells. There was no cellular atypia or invasive growth. The histological diagnosis was MCA.
