Undifferentiated carcinomas of salivary glands are those epithelial malignancies whose light-optic histopathologic features are not sufficient to place them in other defined classes of carcinoma. They are ultrastructurally heterogeneous and can manifest neuroendocrine differentiation. With or without the latter, the carcinomas are biologically high-grade and rank with salivary duct and high-grade mucoepidermoid carcinomas in terms of morbidity and mortality.
唾液腺未分化癌是指那些上皮性恶性肿瘤，其光学显微镜下的组织病理学特征不足以将它们归入其他已定义的癌类别。它们在超微结构上具有异质性，并且可表现出神经内分泌分化。无论有无后者，这些癌在生物学上均为高级别，在发病率和死亡率方面与涎腺导管癌和高级别黏液表皮样癌相当。
