RESUMEN
On the occasion of the coverage of a cervical tumefaction in a child, which led to the diagnosis of acinic cell carcinoma of ectopic salivary gland, the authors conducted a literature review of this tumour. If it is well known to pathologists when it is developed in the major or accessories salivary glands, its location within heterotopy of salivary tissue is much rarer. From a histological point of view it is difficult to distinguish, if primitive location, the occurrence of the tumour in an ectopic salivary gland, its occurrence in intra-node heterotopic salivary tissue. This distinction between glandular ectopia and intra-node heterotopia remains purely theoretical, and does not affect the therapeutic decision. This one remains empirical and discussed on a case-by-case basis for a malignant tumour that is exceptional in this location and at that age.
