Localized Nasopharyngeal Amyloidosis

A mass in the nasopharynx often implies a malignancy in adults, particularly in the endemic areas of Epstein-Barr virus-associated undifferentiated carcinoma. We report an 86-year-old male patient who presented to our rhinologic outpatient department with postnasal drip for several years, with no other associated nasal symptoms. Physical examination with nasal endoscopy found a prominent bulge in the nasopharynx. Pathological examination of the biopsied specimens identified features consistent with amyloidosis. Magnetic resonance imaging demonstrated an enhanced soft-tissue mass localized to the nasopharyngeal region. We excluded the possibility of a partial representation of a potential systemic amyloidosis. Regular follow-up including nasal endoscopy was undertaken. Over 3 years of observation, the disease process remained silent. Here, the clinical presentation, diagnosis and treatment options of this rare entity are discussed.
