Unusual parapharyngeal lesions.

Six cases of unusual parapharyngeal lesions are presented in detail along with discussions of the anatomy, pathology, clinical aspects, and treatment methods of lesions in the parapharyngeal space. Newer techniques of CT scanning and selective embolization are discussed as they apply to management of such lesions. A plasmalymphocytic tumor with amyloidosis is described. The authors believe that such a lesion has not been reported previously in the parapharyngeal space.
