title: Parotolymphatic backflow: a new sign of malignancy.
abstract: The embryology and anatomy of the parotid lymphatics are reviewed. Instances where intraparotid adenopathy can be confused with a parotid tumor are cited. Added to the roentgen signs of parotid malignancy, a new finding, parotolymphatic backflow, is described for what we believe is the first time. Its pathogenesis is discussed.
