Sialadenoma papilliferum is a rare tumor of salivary gland origin and has been reported in the parotid and minor salivary glands of the oral cavity. This tumor is morphologically similar to the papillary syringoadenoma of the sweat gland. We report the clinical and morphologic features of five cases and review the literature. Ultrastructural examination of case 1 revealed the predominant cell type to be an oncocytic cell. These cells contained numerous mitochondria, exhibited parallel filaments within the cell cytoplasm, and were attached by desmosomes. The neoplastic cells appear to exhibit characteristic features of various cell types of the salivary gland duct apparatus.
乳头状唾液腺瘤是一种罕见的起源于唾液腺的肿瘤，已在腮腺和口腔小唾液腺中被报道。该肿瘤在形态学上与汗腺的乳头状汗腺腺瘤相似。我们报告5例的临床和形态学特征并复习相关文献。病例1的超微结构检查显示主要细胞类型为嗜酸性细胞。这些细胞含有大量线粒体，在细胞质内呈现平行细丝，并通过桥粒相连。肿瘤细胞似乎表现出唾液腺导管结构各种细胞类型的特征。
