The presence of heterotopic salivary gland tissue (HSGT) in rather uncommon in the neck. Usually it has been located in its lower third. HSGT in the upper neck is believed to be a rare entity. Two cases of HSGT in the upper neck are presented, with a review of their clinical and histopathological characteristics. The embryologic derivation of salivary tissue and close association with the branchial apparatus are discussed. The possibility of neoplastic transformation must always be considered in these uncommon lesions.
异位唾液腺组织（HSGT）在颈部相当少见。通常它位于颈部下三分之一处。上颈部的HSGT被认为是一种罕见的情况。本文报告了两例上颈部的HSGT病例，并对其临床和组织病理学特征进行了回顾。讨论了唾液组织的胚胎学起源及其与鳃器的密切关系。对于这些罕见病变，必须始终考虑发生肿瘤转化的可能性。
