Salivary tissue can be present in the head and neck outside the usual locations of the major and minor salivary glands. This can be in the form of accessory salivary glands, in association with branchial cleft anomalies, or, less commonly, as heterotopic salivary gland tissue (HSGT). Heterotopic salivary gland tissue is defined as salivary tissue outside of the expected locations of major, minor, and accessory salivary glands with absence of clinical or histologic features of branchial cleft anomalies. Here we present the case of a 13-year-old girl who presented with a draining sinus of the lower neck, which was excised and, on histologic analysis, was consistent with HSGT. We include photographs and histologic images. A review of the literature on heterotopic salivary tissue in the neck is then presented including discussion of the presentation, clinical features, important considerations, and recommendations for management.
唾液腺组织可存在于头颈部，位于大、小唾液腺的通常位置之外。其可为副唾液腺，与鳃裂异常相关，或较少见的为异位唾液腺组织（HSGT）。异位唾液腺组织是指位于大唾液腺、小唾液腺和副唾液腺之外的唾液腺组织，无鳃裂异常的临床或组织学特征。本文报告了 1 例 13 岁女孩，其表现为下颈部有窦道溢液，行切除术，组织学分析符合 HSGT。我们提供了图片和组织学图像。然后对颈部异位唾液腺组织的文献进行了复习，包括其表现、临床特征、重要注意事项以及治疗建议的讨论。
