Abstract

Salivary gland tumors are uncommon and constitute 2–65  of all head and neck neoplasms Tumors of minor salivary gland origin account for less than 25  of all salivary gland neoplasms Papillary cystadenoma of salivary glands is a rare benign epithelial neoplasm characterized by multicystic growth in which the epithelium exhibits adenomatous proliferation Papillary cystadenoma of minor salivary glands most frequently involves the lip buccal mucosa and palate This tumor typically presents as a slowgrowing painless mass usually with diameter of less than 1 cm and clinical resemblance to a mucocele Although most papillary cystadenomas are predominantly of one cell type a regional variability may be presentThis type of minor salivary gland tumor epithelium in the lower lip may be the result of a metaplastic process or simply another neoplastic manifestation of papillary cystadenoma As far as the differential diagnosis of this entity is concerned it is important to distinguish it from papillary cystadenoma lymphomatosum Warthins tumor lowgrade mucoepidermoid carcinoma the papillarycystic variant of acinic cell carcinoma and cystadenocarcinoma Recognition of this lesion is important for the clinician since the differential diagnosis includes lesions with similar clinical appearance and infiltrative behavior
