title: [Embryologic origin of salivary inclusions in the parotid lymph nodes].
abstract: Epithelial salivary ducts included in the lymphoïd tissue are sometimes recognized in the lymph nodes of an adult parotid region. These salivary inclusions into the nodes are in fact constant features of the foetal parotid gland. They arise by progressive development of a lymph node in a salivary lobula: lymphoid cells progressively stuff the lobula and choke the epithelial ducts. So, these salivary inclusions must not be qualified as ectopic.
