Heterotopic salivary tissue.

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.
