Heterotopic salivary tissue can occur in the upper part of the neck and may be confused with other causes of neck masses. The embryologic basis of the heterotopic salivary tissue is considered to be heteroplasia of the epithelium of the cervical sinus of His. Heterotopic salivary tissue should be surgically excised. The diagnosis is easy if there is a draining sinus, but if there is not a sinus, the diagnosis is usually made coincidental to the removal of the mass as part of the evaluation of a neck mass. Benign and malignant neoplasms can arise in such heterotopic salivary tissue.
异位涎腺组织可出现在颈部上部，可能与颈部肿块的其他病因相混淆。异位涎腺组织的胚胎学基础被认为是希氏颈窦上皮的发育异常。异位涎腺组织应手术切除。如果有引流窦，诊断很容易，但如果没有窦，诊断通常是在作为颈部肿块评估的一部分切除肿块时偶然做出的。良性和恶性肿瘤可在这种异位涎腺组织中发生。
