Posterior pharyngeal wall schwannoma (case report).
A rare case of a schwannoma localized on the posterior pharyngeal wall is presented. It concerns a young man with an inflammatory ulcerated mass in the posterior wall of the pharynx causing severe difficulty in swallowing. Although schwannomas of the lateral pharyngeal wall are common, only one case located on the posterior wall has been described. The origin of these tumours at this particular site is thought to be the sympathetic nervous plexus of the posterior pharyngeal wall. In presenting our case, we comment on the origin of posterior pharyngeal wall schwannomas.
