Heterotopic salivary gland tissue at the base of the neck: A case report

A case report of ectopic salivary gland tissue at the base of the neck is presented. Heterotopic salivary gland tissue (HSGT) is found infrequently in the neck. This lesion, present since birth, typically presents as a discharging sinus in the base of the neck. Benign and malignant neoplasms may arise in such HSGT. The origin of HSGT is thought to be heteroplasia of the epithelium of the precervical sinus of His.
