후두와 비인강에 동시에 발생한 아밀로이드증 1예

Amyloidosis is a rare but devasting condition caused by deposition of misfolded proteins as aggregates in the extracellular tissues in various tissues mainly derived from the mesoderm. Amyloidosis in the head and neck is a rare and benign condition that usually takes the form of localized amyloidosis. We experienced a case of a 63-years old women with a localized unilateral mass at the left vestibular fold and bilateral mass on both side of lateral nasopharynx, which were surgically removed and were diagnosed as amyloidosis pathologically. Concurrent amyloidosis of the larynx and the nasopharynx is rare and there are only about one case that have been reported in the literature worldwide until today. We report this case with a review of literature. (J Clinical Otolaryngol 2014;25:261-264)
