title: [Pleomorphic adenoma on heterotopic salivary inclusion: case report and literature review].
abstract: Heterotopic salivary gland tissue is the presence of salivary tissue outside of the salivary glands. It is an uncommon condition but it can be the source of the full spectrum of salivary gland diseases. We present a rare case of pleomorphic adenoma developing from heterotopic salivary gland tissue in an upper neck lymph node not related to the major salivary glands. This article reviews the difficulty of the differential diagnosis with other cervical masses, embryogenesis, clinical manifestations and treatment of this condition.
