Abstract:
This paper presents a case, infrequent and clinically unsuspected, of pleomorphic adenoma in the upper region of the neck in front of the sternocleidomastoid, independent of the salivary glands. The tumor developed within an heterotopic salivary gland of seromucose type, the histopathologic study of the surgical piece being decisive in the diagnosis. The characteristics of salivary heterotopias of the neck, and their diagnostic difficulties and histogenetic problems are reviewed.
