title: Localized amyloidosis masquerading as nasopharyngeal tumor: a review.
abstract: Amyloidosis comprises a diverse collection of disease characterized by the presence of amorphous extracellular eosinophilic deposits of unique protein fibrils that gives apple green birefringence under polarized light after staining with Congo red. Head and neck region is the commonest site for localized form of amyloidosis. We report a case of a 43-year-old man with localized amyloidosis of nasopharynx with oropharyngeal extension and its management, along with a review of relevant literatures.
