[Branchial cysts with heterotopic salivary tissue in the upper third of the neck].
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.
