AN ADEQUATE number of salivary gland tumors in adults have been observed to allow a relatively accurate prediction of the course of the disease once the knowlege has been pooled from the clinical appearance and histologic studies. The behavior of these tumors in the pediatric population, because of the infrequent occurrence in this group, is less well understood.
