Lateral retropharyngeal node metastasis from carcinoma of the upper gingiva and maxillary sinus.
Clinically unsuspected metastases to the lateral retropharyngeal nodes from carcinomas of the upper gingiva or maxillary sinus were found in five patients on follow-up CT examinations. Such uncommon metastases may follow the afferent lymphatic channels from the palate or pharyngeal region or arrive by retrograde lymphatics from positive neck nodes. Careful examination of lateral retropharyngeal nodes may be required in cancers of these primary sites.
