Abstract

A case of amyloidosis localized in the nasopharynx was reported. The patient was a 62-year-old female who complained of persistent nasal obstruction. The gross appearance of this tumor showed a thumb-sized red-yellowish mass, in part covered with white coating. The systemic amyloidosis was excluded by several clinical examinations including rectal biopsy. Histopathological examination revealed diffuse deposits of homogeneous eosinophilic substances. A polarized microscopic examination by congo-red stain showed that deposit's substances were amyloid. A typical amyloid fibril was observed under electron microscope. The mass was removed with Beckmann adenotome. Bleeding was minimal.
