Description

The lateral retropharyngeal node (LRPN) is located in the posterior pharynx space which surrounds the internal carotid artery and prevertebral muscle. LRPN is commonly referred to as the Rouviere lymph nodes. LRPN metastasis often occurs from pharyngeal cancer, but seldom occurs from oral cancer. Oral cancers invading the pharynx sometimes metastasize to LRPN, but the prognosis of those with LRPN metastasis is extremely poor because there is no appropriate treatment for LRPN metastasis. We experienced two patients with oral squamous cell carcinoma which had metastasized to LRPN in spite of no remarkable posterior invasion. One of the two patients underwent parapharyngeal dissection, and one has remained disease-free for 7 years. The mechanism of LRPN metastasis of oral cancer without posterior invasion and the usefulness of parapharyngeal dissection are evaluated.
